Fig. 3C and 3D are top and bottom views, respectively, of the case main body 202 shown in fig. 2. Fig. 3E is a vertically downward cross-sectional view of the housing body 202 shown in fig. 2, taken along section line B-B in fig. 3A, to illustrate further structural details of the interior of the housing body 202. To better describe the structure of the housing main body 202, the extending direction of the first axis X, the second axis Y and the third axis Z is taken as a first direction, the horizontal line direction of the first axis X and the third axis Z is taken as a second direction, and the direction perpendicular to the first direction and the second direction is taken as a third direction.

As shown in fig. 3A-3E, the housing body 202 has a top plate. The top panel includes a first lateral separation panel 120, a second lateral separation panel 323, and a vertical separation panel 324. The first and second lateral partition plates 120 and 323 are disposed to have a step in the first direction to form the step portion 301. First receiving compartment 112 is disposed below first and second transverse partition plates 120 and 323, and second receiving compartment 114 is disposed above first transverse partition plate 120 such that the top of second receiving compartment 114 is partially higher than the top of first receiving compartment 112 in the first direction.

The first transverse partition plate 120 is provided with a perforation 391 therein. The lower portion of the third valve body 136 is capable of passing through the perforations 391 such that the lower portion of the third valve body 136 extends into the first volume 112 and such that the third valve body 136 is capable of rotating about the second axis Y.

The first bottom plate 395 of the first receiving chamber 112 has a concavity 396 for receiving a lower portion of the fourth valve body 138. Since the upper portion of the fourth valve body 138 is connected with the lower portion of the third valve body 136 and the lower portion of the fourth valve body 138 is received in the concavity 396 of the first bottom plate 395, the fourth valve body 138 can be disposed in the first housing 112 and can rotate about the second axis Y.

The second lateral partition plate 323 has a concave portion 393 for receiving an upper portion of the first valve body 132. The second floor 397 of the first housing 112 has a concavity 398 for receiving a lower portion of the second valve body 134. Since the lower portion of the first valve body 132 and the upper portion of the second valve body 134 are sleeved together, the first valve body 132 and the second valve body 134 can be disposed together in the first receiving cavity 112 and can rotate around the first axis X.

Second transverse divider plate 323 also has a recess 394 for receiving an upper portion of drive shaft 118 to enable drive shaft 118 to rotate about third axis Z when actuator drives drive shaft 118 to rotate.

Fig. 3F is a cross-sectional view of the housing body 202 shown in fig. 2 taken parallel to section line C-C in fig. 3A to more clearly illustrate the shape of the first cavity 112. As shown in fig. 3F, first receptacle 112 is generally shaped as three intersecting cylinders, thereby forming a first cut cylinder receptacle 311, a second cut cylinder receptacle 312, and a third cut cylinder receptacle 313. First valve body 132 and second valve body 134 are disposed in first cut cylinder receptacle 311, drive shaft 118 is disposed in second cut cylinder receptacle 312, and fourth valve body 138 is disposed in third cut cylinder receptacle 313. The central axis M of the first cut cylinder receiving cavity 311 coincides with the first axis X, the central axis N of the second cut cylinder receiving cavity 312 coincides with the third axis Z, and the central axis O of the third cut cylinder receiving cavity 313 coincides with the second axis Y.

As can be seen in fig. 3A-3E, a first set of flow ports is provided on the wall of the first volume 112, and the first set of flow ports includes a first flow port 361 arranged along the third direction and a second flow port 362 arranged in the opposite direction along the third direction. The first communication port 361 and the second communication port 362 are provided at the same height in the first direction, and the first communication port 361 and the second communication port 362 are provided at heights such that the first communication port 361 and the second communication port 362 can be fitted to the first valve body 132. In other words, when the first valve body 132 rotates, the first communication port 361 and/or the second communication port 362 can be selectively communicated or cut off.

The first set of ports further includes a third port 363, and the third port 363 is disposed in a range of an angle between a reverse direction of the second direction and the third direction, and is disposed at a lower height in the first direction than the first port 361 and the second port 362. The third port 363 is elevationally configured to enable the third port 363 to mate with the second valve body 134. In other words, the third communication port 363 can be selectively connected or disconnected when the second valve body 134 is rotated.

The first set of ports further comprises a fourth port 364, the fourth port 364 being arranged in a range of angles between a reverse direction of the second direction and a reverse direction of the third direction and being arranged slightly lower in the first direction than the third port 363. The fourth communication port 364 is provided at a lower height than the second valve body 134. In other words, the fourth fluid port 364 remains in fluid communication with the first volume 112 regardless of the angle to which the second valve body 134 is rotated.

Wherein each of first port 361, second port 362, third port 363, and fourth port 364 are disposed around first cut cylindrical cavity 311 in a third direction about central axis M of first cut cylindrical cavity 311.

The first set of ports further includes a fifth port 365 disposed within a range opposite the third direction and at an angle to the second direction and disposed at a height slightly lower than the second port 362 in the first direction. The height of the fifth communication port 365 is set such that the fifth communication port 365 is fitted to the fourth valve body 138. In other words, when the fourth valve body 138 rotates, the fifth communication port 365 can be selectively communicated or cut off. Further, fifth communication port 365 is disposed in third tangential cylindrical cavity 313 in a third direction around central axis O of third tangential cylindrical cavity 313.

Each of the first, second, third, fourth, and fifth communication ports 361, 362, 363, 364, and 365 has a pipe provided therearound and extending outward from the case main body 202, so that each communication port can be connected to other devices or pipes through the pipe.

Fig. 3G is a sectional view of the case main body 202 shown in fig. 2 along a section line D-D in fig. 3D to show a specific arrangement of the sixth communication port 366 and its conduits. As shown in fig. 3G, the first set of flow ports further comprises a sixth communication port 366, the sixth communication port 366 being arranged at the intersection of the cavity wall of first cut cylindrical receptacle 311 and the cavity wall of second cut cylindrical receptacle 312. The sixth communication port 366 is arranged within an angle between the reverse of the third direction and the second direction, and its set height in the first direction is slightly lower than the second communication port 362. The height of the sixth communication port 366 is set such that the sixth communication port 366 mates with the second valve body 134. In other words, when the second valve body 134 rotates, the sixth communication port 366 can be selectively communicated or disconnected.

As seen in fig. 2, the conduit 370 is disposed around the sixth communication port 366 and extends outwardly from the housing main body 202. The nozzle 375 of the duct 370 is blocked by the cover 203 so that fluid cannot flow into or out of the housing body 202 from the nozzle 375. The housing body 202 also includes a conduit 371 disposed perpendicular to the conduit 370. Tubing 371 is in fluid communication with tubing 370. Thus, the fluid flowing out of or into the housing main body 202 from the sixth communication port 366 can flow through the orifices 373,374 of the conduit 371.

With continued reference to figures 3A-3E, a second set of flow ports is provided in the wall of second volume 114, the second set of flow ports including a seventh communication port 367 and an eighth communication port 368. The seventh communication port 367 is arranged within a range of an angle between the second direction and the third direction, and is disposed higher in the first direction than the fourth communication port 364. The eighth communication port 368 is arranged within a range of an angle between the reverse of the third direction and the second direction, and its set height in the first direction is slightly lower than the seventh communication port 367. The seventh communication port 367 and the eighth communication port 368 are provided at heights such that the seventh communication port 367 and the eighth communication port 368 can be fitted to the third valve body 136. In other words, when the third valve body 136 rotates, the seventh communication port 367 and/or the eighth communication port 368 can be selectively communicated or disconnected.

Each of the seventh and eighth communication ports 367 and 368 has a conduit provided therearound and extending outwardly from the housing main body 202, thereby enabling the respective flow-through ports to be connected with other devices or conduits through the conduits.

The second set of flow ports also includes a pump outlet communication port 369. A pump outlet communication port 369 is provided in the vertical partition plate 324 for connection to a pump outlet (not shown). Specifically, the pump outlet communication port 369 is disposed within an included angle between a reversal of the second direction and a reversal of the third direction, and the pump outlet communication port 369 is set at a height such that the pump outlet communication port 369 mates with the third valve body 136. In other words, the pump outlet communication port 369 can be selectively communicated or interrupted as the third valve body 136 rotates.

As one example, the regulator valve 100 of the present application uses a pump (not shown) as a source of fluid flow. As shown in fig. 3A, the second transverse partition plate 323 at the top of the first receiving chamber 112 has a plurality of through holes 342 for connecting with the inlet of the pump. An opening 399 in the top of second plenum 114 can be capped by a pump. Thus, fluid in the first chamber 112 can exit the housing 101 through the plurality of holes 242 and enter the pump, and subsequently fluid exiting through the pump outlet can enter the second chamber 114 through the pump outlet communication port 369.

As one example, an actuator (not shown) is used herein as a power source for driving rotation of shaft 118. As shown in fig. 3B, the bottom of the first cavity 112 has a circular hole 303 for positioning an actuator. Through the hole 303, the actuator can be coupled to the drive shaft 118, thereby driving the drive shaft 118 to rotate.

FIG. 4A is a perspective view of the drive shaft 118 shown in FIG. 1B from an angle from top to bottom; fig. 4B is a perspective view of the drive shaft shown in fig. 1B from another angle, looking down and up. As shown in fig. 4A and 4B, the drive shaft 118 includes a shaft 401. The upper end 410 of the shaft 401 is designed to mate with a recess 394 in the housing body 202 so that the shaft 401 can be rotatably connected with the housing 101. The lower end 412 of the shaft 401 is designed to mate with the output end of the actuator so that the drive shaft 118 can be driven to rotate when the actuator is operated.

The regulator valve 100 further comprises a first clutchable drive structure 402, a second clutchable drive structure 403 and a third clutchable drive structure 404 disposed on the shaft 401. In particular, a first clutchable drive structure 402 is provided on the upper portion of the shaft 401. The first clutchable drive structure 402 includes a first transverse plate 422 and a plurality of first bars 424,426,428. The first transverse plate 422 is substantially in the shape of a sector, which is transversely provided on the upper portion of the shaft 401 such that the circumferential direction of the sector coincides with the circumferential direction of the shaft 401. The center of the sector coincides with the axis of the shaft 401 so that when the drive shaft 118 rotates about the first axis X, the plurality of first bars 424,426,428 on the first cross plate 422 also rotate about the first axis X. The plurality of first bars 424,426,428 are disposed uniformly in the vicinity of the outer edge of the first transverse plate 422 in the circumferential direction of the first transverse plate 422 and extend downward from the bottom surface of the first transverse plate 422. The first plurality of levers 424,426,428 are configured to cooperate with the first disengagable drive structure 555 on the first valve body 132 such that the first disengagable drive structure 402 on the drive shaft 118 (i.e., at least one of the first plurality of levers 424,426,428) is configured to rotate the first valve body 132 together when the drive shaft 118 is rotated through a first angular range.

The second clutchable drive structure 403 includes a second transverse arm 432 and a second lever 433. The second transverse arm 432 is generally elongate and extends perpendicularly from the shaft 401 in a radial direction of the shaft 401, such that when the shaft 401 is rotated, the distal end 436 of the second transverse arm 432 is also capable of circular movement. A second rod 433 is disposed at a distal end 436 of the second transverse arm 432 and extends upwardly from an upper surface of the second transverse arm 432. The second rod 433 is configured to cooperate with a second disengagable drive structure 755 of the second valve body 134 such that, when the drive shaft 118 is rotated within a second angular range, the second disengagable drive structure 403 of the drive shaft 118 (i.e., the second rod 433) rotates the second valve body 134 together.

The third clutchable drive structure 404 includes a third transverse arm 442 and a third rod 443. The third transverse arm 442 is substantially elongated and extends perpendicularly from the upper portion of the shaft 401 in a radial direction of the shaft 401, so that when the shaft 401 rotates, the distal end 446 of the third transverse arm 442 is also able to move circumferentially. A third rod 443 is disposed at the distal end 446 of the third transverse arm 442 and extends downwardly from the lower surface of the third transverse arm 442. The third rod 443 is configured to cooperate with the third disengagable driven structure 955 on the third valve body 136 and the fourth disengagable driven structure 1155 on the fourth valve body 138 such that the third disengagable driving structure 404 on the drive shaft 118 (i.e., the third rod 443) rotates the third valve body 136 when the drive shaft 118 rotates within the third angular range; and when the drive shaft 118 rotates within the fourth angular range, the third disengagable drive structure 404 (i.e., the third rod 443) on the drive shaft 118 can rotate the fourth valve body 138.

Fig. 5A is a perspective view of the first valve body 132 shown in fig. 1B, as viewed from above; fig. 5B is a perspective view of the first valve body 132 shown in fig. 1B, viewed from below. As shown in fig. 5A and 5B, the first valve body 132 is a substantially spherical body cut up and down, and has a rotation shaft 162. The lower portion of the rotation shaft 162 is provided with a recess 552, thereby forming the sleeve 155. The sleeve 155 is adapted to receive the upper end of the rotary shaft 164 of the second valve body 134, thereby enabling the first valve body 132 and the second valve body 134 to rotate about the same first axis X. The upper portion 402 of the first valve body 132 is designed to mate with the recessed portion 393 of the second lateral divider plate 323 such that the upper portion 402 of the first valve body 132 can be received by the recessed portion 393.

The first valve body 132 is provided with a first clutchable driven structure 555 on a ball thereof, the first clutchable driven structure 555 includes a plurality of first grooves 512,513,514,515,516,517, a plurality of first grooves 512,513,514,515,516,517 are provided on an upper surface of the ball of the first valve body 132 and are arranged along a circumferential direction of the first valve body 132, specifically, the plurality of first grooves 512,513,514,515,516,517 are formed by being slotted from an edge of the ball of the first valve body 132 to an inside of the ball, and a central angle formed by a distribution of the plurality of first grooves 512,513,514,515,516,517 on the ball of the first valve body 132 is β.

Two openings 562,564 are provided in the first valve body 132, and the two openings 562,564 are configured such that when the first valve body 132 is rotated, at least one of the two openings 562,564 can be selectively aligned with the first and/or second flow opening 361, 362 on the cavity wall of the first volume 112, thereby respectively opening and closing off the first and second flow openings 361, 362.

Fig. 6 is a schematic view of the mating relationship of the first valve body 132 and the drive shaft 118 to illustratively show one of the states of engagement of the first clutched drive structure 402 and the first clutched driven structure 555. As shown in fig. 6, at least one of the first plurality of bars 424,426,428 on the drive shaft 118 is engageable with at least one of the first plurality of slots 512,513,514,515,516,517 when the drive shaft 118 is rotated within a first angular range. Thereby, the driving shaft 118 can rotate the first valve body 132.

It should be noted that although the first valve body 132 is sleeved on the second valve body 134, the second valve body 134 does not rotate along with the first valve body 132 when the first valve body 132 rotates because there is a friction force between the first valve body 132 and the second valve body 134.

FIG. 7A is a perspective view from above of the second valve body 134 shown in FIG. 1B; fig. 7B is a perspective view of the second valve body 134 shown in fig. 1B, viewed from below. As shown in fig. 7A and 7B, the second valve body 134 includes a second valve body 733 and a rotation shaft 164. The top of the shaft 164 is stepped and is received by a sleeve 155 at the lower portion of the first valve body 132, so that the first valve body 132 and the second valve body 134 can rotate about the same first axis X.

The second valve body 733 is substantially a spherical shell cut at the top and bottom, and the second valve body 733 is provided around the rotary shaft 164. The lower portion of the second valve body 733 is fixedly connected to the rotary shaft 164 via a plurality of connecting posts 704,706, 708. An opening 762 is provided in the second valve body 733, the opening 762 being configured such that, upon rotation of the second valve body 134, the opening 762 can selectively align with the third communication port 363 and/or the sixth communication port 366 in the wall of the first volume 112, thereby enabling communication and disconnection of the third communication port 363 and the sixth communication port 366.

The lower portion of the shaft 164 is provided with a second clutchable driven structure 755. The second clutched driven structure 755 includes a second valve body plate 712. One end of the second valve body plate 712 is connected to a lower portion of the rotation shaft 164, and the other end of the second valve body plate 712 is provided with a second groove 722, the second groove 722 being arranged in a radial direction of the second valve body 134. When the drive shaft 118 is rotated within the second angular range, the second stem 433 on the drive shaft 118 is able to engage the second slot 722 on the second valve body 134.

Fig. 8 is a schematic diagram of the mating relationship of the second valve body 134 and the drive shaft 118 to exemplarily illustrate one of the states in which the second clutched drive structure 403 is engaged with the second clutched driven structure 755. As shown in fig. 8, when the drive shaft 118 rotates within a second angular range, the second rod 433 on the drive shaft 118 engages the second slot 722. Thereby, the driving shaft 118 can drive the second valve body 134 to rotate in the second angle range.

It should be noted that although the first valve body 132 is sleeved on the second valve body 134, the first valve body 132 does not rotate along with the rotation of the second valve body 134 when the second valve body 134 rotates because the first valve body 132 and the second valve body 134 have friction therebetween.

FIG. 9A is a perspective view of the third valve body 136 shown in FIG. 1B from an angle from top to bottom; fig. 9B is a perspective view of the third valve body 136 shown in fig. 1B from another angle, looking down and up. As shown in fig. 9A and 9B, the third valve body 136 includes a third valve body 933 and a rotary shaft 166. The top of the shaft 166 is received by a coupling on the pump and the lower portion of the shaft 166 is provided with a recess 902 to form the sleeve 156. The sleeve 156 is adapted to receive the upper end of the shaft 168 of the fourth valve body 138, thereby enabling the third valve body 136 and the fourth valve body 138 to rotate about the same second axis Y.

The third valve body 933 is substantially spherical shell-shaped and is disposed around the rotating shaft 166. The lower portion of the third valve body 933 is fixedly connected to the rotary shaft 166 by a connection plate 904. Two openings 962,964 are provided in the third valve body 933, and the two openings 962,964 are configured such that when the third valve body 136 is rotated, at least one of the two openings 962,964 can be selectively aligned with the pump outlet communication port 369, the seventh communication port 367 and/or the eighth communication port 368 on the chamber wall of the second volume chamber 114, thereby achieving communication and disconnection of the pump outlet communication port 369, the seventh communication port 367 and the eighth communication port 368.

The lower portion of the shaft 166 is provided with a third disengagable driven structure 955. The third disengagable driven structure 955 includes a third valve plate 912. One end of the third valve plate 912 is connected to the lower portion of the rotating shaft 166, and the other end of the third valve plate 912 is provided with a third groove 922, and the third groove 922 is arranged along the radial direction of the third valve body 136. When the drive shaft 118 is rotated within the third angular range, the third rod 443 on the drive shaft 118 is able to engage the third slot 922 on the third valve body 136.

Fig. 10 is a schematic diagram of the third valve body 136 in mating relationship with the drive shaft 118 to exemplarily illustrate one of the states in which the third clutched driving structure 404 is engaged with the third clutched driven structure 955. As shown in FIG. 10, when the drive shaft 118 rotates within the third angular range, the third rod 443 on the drive shaft 118 engages the third slot 922 on the third valve body 136. Thereby, the driving shaft 118 can drive the third valve body 136 to rotate within the third angular range.

It should be noted that although the third valve body 136 is sleeved on the fourth valve body 138, the third valve body 136 and the fourth valve body 138 have friction therebetween, so that when the third valve body 136 rotates, the fourth valve body 138 does not rotate along with the rotation of the second valve body 134.

FIG. 11A is a perspective view of the fourth valve body 138 shown in FIG. 1B from an angle from top to bottom; fig. 11B is a perspective view of the fourth valve body 138 shown in fig. 1B from another angle, from below to above. As shown in fig. 11A and 11B, the fourth valve body 138 includes a fourth valve body 1133 and a shaft 168. The top of the shaft 166 is stepped and is received by the sleeve 156 at the lower part of the third valve body 136, so that the third valve body 136 and the fourth valve body 138 can rotate about the same second axis Y.

The fourth valve body 1133 is generally spherical shell shaped and is disposed about the shaft 168. The upper part and the lower part of the fourth valve body 1133 are respectively provided with a connecting plate 1104,1105 fixedly connected with the rotating shaft 168. The fourth valve body 1133 is provided with three openings 1162,1164,1166, and the three openings 1162,1164,1166 are configured such that when the fourth valve body 138 is rotated, at least one of the three openings 1162,1164,1166 can be selectively aligned with the fourth communication port 364 on the chamber wall of the first chamber 112, thereby enabling communication and disconnection of the fourth communication port 364.

The upper portion of the shaft 168 is provided with a fourth clutched driven structure 1155. The fourth clutched driven structure 1155 includes a fourth valve body plate 1112. One end of the fourth valve body plate 1112 is connected to the upper portion of the rotation shaft 168, and a fourth groove 1122 is formed in the other end of the fourth valve body plate 1112, and the fourth groove 1122 is arranged in the radial direction of the fourth valve body 138. When the drive shaft 118 is rotated through a fourth angular range, the third rod 443 on the drive shaft 118 can engage the fourth slot 1122 on the fourth valve body 138.

Fig. 12 is a schematic illustration of the mating relationship of the fourth valve body 138 and the drive shaft 118 to schematically illustrate one of the states of engagement of the third disengagable drive structure 404 and the fourth disengagable driven structure 1155. As shown in fig. 12, when the drive shaft 118 rotates within a fourth angular range, the third rod 443 on the drive shaft 118 engages the fourth slot 1122. Thus, the driving shaft 118 can drive the fourth valve body 138 to rotate within the fourth angular range.

It should be noted that although the fourth valve body 138 is sleeved on the fourth valve body 138, the third valve body 136 does not rotate along with the rotation of the fourth valve body 138 when the fourth valve body 138 rotates because the third valve body 136 and the fourth valve body 138 have friction therebetween.

It should also be noted that in the embodiments of the present application, the third disengagable driven structure 955 and the fourth disengagable driven structure 1155 cooperate with the third disengagable driving structure 404, respectively, to form a third clutching structure and a fourth clutching structure. However, since the groove walls of the third groove 922 on both sides and the groove walls of the fourth groove 1122 on both ends have different lengths, the engagement and disengagement times of the third clutch structure and the fourth clutch structure are different. In an embodiment of the present application, the third clutch structure can be engaged when the drive shaft 118 is rotated within a third angular range, and the fourth clutch structure can be engaged when the drive shaft 118 is rotated within a fourth angular range.

Since the first clutch structure, the second clutch structure, the third clutch structure and the fourth clutch structure in the present application are generally all engaged and disengaged in a way of using a groove and a rod, in order to clearly illustrate the specific matching relationship among the clutch structures, the third clutch structure is taken as an example in the present application and is explained in detail.

13A-13H are schematic diagrams of the third clutching structure during operation to illustrate how the third clutching structure achieves engagement and disengagement. Specifically, the third clutched structure includes a third clutched drive structure 404 and a third clutched driven structure 955, and when the drive shaft 118 rotates within a third angular range, the third clutched drive structure 404 is able to engage with the third clutched driven structure 955, thereby causing the third clutched driven structure 955 to rotate together; when the driving shaft 118 rotates outside the third angular range, the third disengagable driving structure 404 is disengaged from the third disengagable driven structure 955, and thus the third disengagable driven structure 955 is not rotated. The relative positional relationship of the shaft 401 of the drive shaft 118, the third transverse arm 442 and the third rod 443 is schematically illustrated in fig. 13A-13H. When the drive shaft 118 rotates, the shaft 401, the third transverse arm 442 and the third rod 443 rotate together about the third axis Z. Fig. 13A to 13H also schematically show the relative positional relationship of the rotary shaft 166 of the third valve body 136, the third valve plate 912 and the third groove 922. When the third valve body 136 rotates, the rotating shaft 166, the third valve plate 912, and the third groove 922 rotate together about the second axis Y.

Fig. 13A shows the relative positional relationship of the third clutched driving structure 404 and the third clutched driven structure 955 when the drive shaft 118 has not yet rotated to the initial angle of the third angular range. Specifically, the actuator rotates the drive shaft 118 in a counterclockwise direction (e.g., in the direction of arrow T in fig. 13A), and thus the third clutchable drive structure 404 also rotates in a counterclockwise direction. While the third disengagable driven structure 955 remains in the first position because it is not being driven by the actuator.

Fig. 13B illustrates the relative positional relationship of the third clutched driving structure 404 and the third clutched driven structure 955 as the drive shaft 118 rotates to the first boundary angle of the third angular range. Specifically, when the drive shaft 118 rotates counterclockwise to the initial angle of the third angular range, the third rod 443 of the drive shaft 118 contacts the first sidewall 1302 of the third slot 922, and thus the third rod 443 is received in the third slot 922.

Fig. 13C illustrates the relative positional relationship of the third clutched driving structure 404 and the third clutched driven structure 955 as the drive shaft 118 rotates counterclockwise through a third angular range. Specifically, as the drive shaft 118 continues to rotate in the counterclockwise direction, the third rod 443 pushes against the first side wall 1302 of the third slot 922, thereby rotating the third valve plate 912. As a result, the third disengagable driving structure 404 drives the third disengagable driven structure 955 to rotate in a clockwise direction (e.g., as shown by arrow U in fig. 13C).

Fig. 13D shows that the third clutched driving structure 404 is disengaged from the third clutched driven structure 955 when the drive shaft 118 is rotated to a second boundary angle of the third angular range. Fig. 13E shows that the third clutched driving structure 404 is disengaged from the third clutched driven structure 955 when the drive shaft 118 rotates outside of the third angular range. Specifically, as the drive shaft 118 continues to rotate in the counterclockwise direction, the third rod 443 disengages from the third slot 922, thereby allowing the drive shaft 118 to continue to rotate in the counterclockwise direction while the third clutched driven structure 955 remains in the second position. That is, at this time, the third disengagable driving structure 404 cannot drive the third disengagable driven structure 955 to rotate.

Fig. 13F illustrates the relative positional relationship of the third clutched driving structure 404 and the third clutched driven structure 955 as the drive shaft 118 rotates to a second boundary angle of the third angular range. Specifically, when the drive shaft 118 rotates in a clockwise direction (e.g., as indicated by arrow P in fig. 13F), the third clutchable drive structure 404 also rotates in a clockwise direction. The third rod 443 of the drive shaft 118 contacts the second sidewall 1304 of the third slot 922, and thus the third rod 443 is received in the third slot 922.

Fig. 13G shows the relative positional relationship of the third clutched driving structure 404 and the third clutched driven structure 955 as the drive shaft 118 rotates clockwise through a third angular range. Specifically, as the drive shaft 118 continues to rotate in the clockwise direction, the third rod 443 pushes the second side wall 1304 of the third slot 922, thereby rotating the third valve plate 912. As a result, the third disengagable driving structure 404 drives the third disengagable driven structure 955 to rotate in a counter-clockwise direction (e.g., as shown by arrow V in fig. 13G).

Fig. 13H shows that the third clutched driving structure 404 is disengaged from the third clutched driven structure 955 when the drive shaft 118 is rotated to the first boundary angle of the third angular range. Specifically, as the drive shaft 118 continues to rotate in the clockwise direction, the third rod 443 disengages from the third slot 922, thereby allowing the drive shaft 118 to continue to rotate in the clockwise and counterclockwise directions while the third disengagable driven structure 955 remains in the first position. That is, at this time, the third disengagable driving structure 404 cannot drive the third disengagable driven structure 955 to rotate.

It should be noted that the angle at which the rotation of the third disengagable driving structure 404 can engage with the third disengagable driven structure 955 to rotate the third disengagable driven structure 955 is referred to as a third angular range.

With continued reference to fig. 4A-4B, it can be seen that the first clutchable drive structure 402, the second clutchable drive structure 403 and the third clutchable drive structure 404 disposed on the shaft 401 are disposed along different angular directions of the shaft 401. Such an arrangement may enable the clutched drive structure on the shaft 401 to selectively engage the clutched driven structure on the valve body when the shaft 401 is rotated through different angles, thereby driving rotation of different valve bodies.

In the present application, the specific structures and positional relationships of the first valve body 132, the second valve body 134, the third valve body 136, and the fourth valve body 138 and the first clutch structure, the second clutch structure, the third clutch structure, and the fourth clutch structure are configured to enable: the opening of the first valve body 132 is capable of being fitted with the first communication port 361 and the second communication port 362, so that the opening of the first valve body 132 is capable of selectively opening at least one of the first communication port 361 and the second communication port 362; the opening in the second valve body 134 is configured to mate with the third port 363 and the sixth port 366 such that the opening in the second valve body 134 is configured to selectively open at least one of the third port 363 and the sixth port 366; the openings in the third valve body 136 are capable of cooperating with the seventh communication port 367 and the eighth communication port 368 such that the openings in the third valve body 136 are capable of selectively opening at least one of the seventh communication port 367 and the eighth communication port 368; the opening in the fourth valve body 138 is capable of mating with the fifth port 365 such that the opening in the fourth valve body 138 is capable of selectively opening the fifth port 365.

As the drive shaft 118 rotates, one or more of the first, second, third and fourth valve bodies 132, 134, 136, 138 are selectively rotated to create different flow passages within the regulator valve 100. As one example, the regulator valve 100 is capable of achieving a variety of communication relationships as shown in Table 1.

TABLE 1

The left hand indices 1-10 in Table 1 indicate different degrees of rotation of the drive shaft 118, e.g., index 1 indicates that the drive shaft 118 is rotated at a first angle. It should be noted that, as an example, reference numerals 1 to 10 indicate angles at which the drive shaft 118 is rotated in the same direction from an initial angle. It is further noted that the drive shaft 118 is configured to be capable of bi-directional rotation (i.e., clockwise rotation and counterclockwise rotation).

The symbol "O" in Table 1 indicates that the communication port is in a fully communicated state, i.e., the communication port on the housing is aligned with the opening on the valve body, thereby enabling fluid to flow through the full area of the communication port on the housing, the symbol "R" in Table 1 indicates that the communication port is in a partially communicated state, i.e., the communication port on the housing is partially aligned with the opening on the valve body, thereby enabling fluid to flow only partially through the communication port aligned with the opening on the valve body, the symbol "×" in Table 1 indicates that the communication port is in a blocked state, i.e., the communication port is blocked by the body of the valve body, thereby disabling fluid flow through the communication port.

By controlling the opening and closing states of the circulation ports on the respective housings and the mutual fitting between the respective valve bodies, a plurality of circulation passages, each of which is used to communicate the corresponding two circulation ports, can be formed in the valve 100, so that the external pipelines connected to the two corresponding circulation ports can be communicated through the circulation passages. The several flow passages in the valve 100 can be switched on or off by controlling the rotation of the respective valve bodies. For example, if the fourth communication port 364 listed in table 1 is used as the fluid inlet of the valve 100 and the remaining seven communication ports are used as the fluid outlets of the valve 100, there are seven communication channels in the valve 100, including communication channel 1, communication channel 2, communication channel 3, communication channel 5, communication channel 6, communication channel 7, and communication channel 8. The flow channel 1 communicates with the fourth port 364 and the first port 361, the flow channel 2 communicates with the fourth port 364 and the second port 362, the flow channel 3 communicates with the fourth port 364 and the third port 363, the flow channel 5 communicates with the fourth port 364 and the fifth port 365, the flow channel 6 communicates with the fourth port 364 and the sixth port 366, the flow channel 7 communicates with the fourth port 364 and the seventh port 367, and the flow channel 8 communicates with the fourth port 364 and the eighth port 368.

When the valve 100 is at the first angle, the opening in the first valve body 132 is aligned with the fourth communication port 364 such that the first communication port 151 is opened; the opening on the first valve body 132 is aligned with the second communication port 362 so that the second communication port 362 is opened; the opening on the second valve body 134 is aligned with the third port 363 such that the third port 363 is open; the opening in the fourth valve body 138 is aligned with the fifth communication port 365 such that the fifth communication port 365 is opened; the opening on the third valve body 136 is aligned with the seventh communication port 367, so that the seventh communication port 367 is opened; the opening in the third valve body 136 is aligned with the eighth port 368 such that the eighth port 368 is opened; and the opening in the second valve body 134 is not aligned with the sixth communication port 366 such that the sixth communication port 366 is closed or blocked. At this time, the flow channel 1 that communicates the fourth port 364 with the first port 361 is connected, the flow channel 2 that communicates the fourth port 364 with the second port 362 is connected, the flow channel 3 that communicates the fourth port 364 with the third port 363 is connected, the flow channel 5 that communicates the fourth port 364 with the fifth port 365 is connected, the flow channel 7 that communicates the fourth port 364 with the seventh port 367 is connected, the flow channel 8 that communicates the fourth port 364 with the eighth port 368 is connected, and the flow channel 6 that communicates the fourth port 364 with the sixth port 366 is disconnected.

When the valve 100 is at the second angle, the opening in the first valve body 132 is aligned with the fourth fluid port 364 such that the first fluid port 151 is opened; the opening on the first valve body 132 is aligned with the second communication port 362 so that the second communication port 362 is opened; the opening on the second valve body 134 is aligned with the third port 363 such that the third port 363 is open; the opening in the fourth valve body 138 is aligned with the fifth communication port 365 such that the fifth communication port 365 is opened; the opening in the second valve body 134 is aligned with the sixth communication port 366 such that the sixth communication port 366 is opened; the opening on the third valve body 136 is aligned with the seventh communication port 367, so that the seventh communication port 367 is opened; the opening in the third valve body 136 is aligned with the eighth communication port 368 such that the eighth communication port 368 is opened. At this time, the flow channel 1 that communicates the fourth port 364 with the first port 361 is communicated, the flow channel 2 that communicates the fourth port 364 with the second port 362 is communicated, the flow channel 3 that communicates the fourth port 364 with the third port 363 is communicated, the flow channel 5 that communicates the fourth port 364 with the fifth port 365 is communicated, the flow channel 6 that communicates the fourth port 364 with the sixth port 366 is communicated, the flow channel 7 that communicates the fourth port 364 with the seventh port 367 is communicated, and the flow channel 8 that communicates the fourth port 364 with the eighth port 368 is communicated.

Similarly, the on and off states of the respective flow passages in the valve 100 when the valve 100 is at the third to tenth angles can be found from table 1.

It should be noted that the valve 100 of the embodiment shown in fig. 1A-14 is not limited to the above-described application. The purpose of switching the cooling path is achieved by arranging a power unit such as a pump and forming various different flow passages in the valve 100 according to the need of the cooling path of the cooling system, and using the valve 100 as a switching device for the cooling path.

Although the clutch structure is described herein with a slot and a rod as an example, those skilled in the art will appreciate that other engagement means (e.g., clasping means, gear engagement) for achieving such clutching and declutching are within the scope of the present application. The regulating valve 100 of the present application can realize the switching of channels different in fluid by the arrangement of the opening on the valve body and the flow port on the housing, and also can control the flow rate of each channel. The arrangement can enable the control assembly in the system to control fewer elements to realize the switching of channels with different fluids, and can enhance the stability of system control while integrating control.

To ensure sealing between the flow ports and the valve body when each of the flow ports in the regulator valve 100 is not aligned with an opening in the valve body (i.e., the flow ports are closed), the regulator valve 100 further includes a first set of seals and a second set of seals. Each of the first set of seals is disposed between the first, second, and fourth valve bodies 132, 134, 138 and each of the first set of ports. Each of the first set of seals is configured to abut against a wall of the chamber in which each of the first set of flow ports is located such that the first set of seals can abut against the wall of the chamber when the valve body is rotated without rotating with the rotation of the valve body. The second set of seals includes two seals, one of which is disposed between the seventh communication port 367 and the third valve body 136 and the other of which is disposed between the eighth communication port 368 and the third valve body 136. Since the pump outlet communication port 369 in the second set of flow ports is connected to the outlet of the pump, no sealing ring is provided.

When the valve body rotates, the friction exists between the valve body and the sealing piece, so that the actuator driving the valve body to rotate needs larger driving force, and the valve body is driven to rotate so as to overcome the friction force between the valve body and the sealing piece. When a traditional regulating valve drives one or more valve bodies to rotate, the driving shaft of the regulating valve needs to overcome the friction force caused by all sealing elements arranged in the valve bodies, so that the required power of an actuator is larger. While the drive shaft 118 of the drive mechanism of the regulator valve 100 of the present application selectively engages the drive structure with the driven structure at the same time, the drive structure is capable of rotating the driven structure such that the drive shaft 118 rotates the driven member (i.e., at least one of the first valve body 132, the second valve body 134, the third valve body 136, and the fourth valve body 138).

The regulator valve 100 in the present application also has the following advantages: when the passage of the regulating valve 100 requiring flow is realized by the rotation of the valve body on one side of the driving shaft 118, no friction force is generated between the non-rotating valve body and the sealing member because the valve body on the other side is not rotated, so that the driving force provided by the actuator is reduced, and only the friction force which needs to be overcome by the valve body which needs to rotate by the driving shaft 118 needs to be provided. The states of the valve bodies in the regulator valve 100 at numbers 8-10 in table 1 will be described as an example.

Fig. 14 is a schematic diagram of the regulator valve 100 shown in fig. 1A cut in a horizontal direction to the first communication port 361 and the second communication port 362, and fig. 14 shows a first seal 1402 provided between the first valve body 132 and the first communication port 361, a second seal 1404 provided between the first valve body 132 and the second communication port 362, and a third seal 1406 provided between the fourth valve body 138 and the fifth communication port 365. When the drive shaft 118 is rotated through the angular range shown by reference numerals 8-10, only the first valve body 132 and the second valve body 134 need to be rotated, and thus the actuator driving the drive shaft 118 to rotate only needs to provide a frictional force capable of overcoming the sealing elements on the first valve body 132 and the second valve body 134.

Therefore, the control valve of the present application is particularly suitable for applications that provide more flow passages when the actuator has a constant driving force, because the drive shaft of the control valve of the present application only needs to overcome the friction generated by the seals between the driven valve body and the housing, and does not need to overcome the friction generated by all the seals between the valve body and the housing at the same time, and therefore, does not need to increase the output of the actuator 190 with the increase of the flow passages in the valve.

While only certain features of the application have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the application.
