Detailed Description

The invention mainly comprises six main components.

As shown in fig. 2, the names are:

the cylinder jacket 8: the cylinder jacket 8 is a thin-walled part with the thickness of t, the outer radius of the thin-walled part is R + t, and the inner radius of the thin-walled part is R. The end surface curves coincide with the end surface curves of the first stator 3 and the second stator 4. The first stator 3, the second stator 4, the rotor 2 and the rotor sleeve 1 are assembled and connected with the stator according to requirements. A vent hole 9 is formed at an appropriate position of the cylinder jacket 8 so that gas exchange can be performed between the inner and outer walls.

First stator 3, second stator 4: the first stator 3 and the second stator 4 have the same structure and are made of cylinders with an inner radius R and an outer radius R + t. The first stator 3 and the second stator 4 are each provided with a mounting ring groove 27 having a thickness t. The first stator 3 and the second stator 4 are twisted by 90 ° along the axis to form a phase difference when mounted. The cooling cavity 6 is arranged, and cooling water can circulate in the cooling cavity 6 when the internal combustion engine works, so that the internal combustion engine is ensured to be at a proper temperature.

And (3) a rotor 2: the rotor 2 has a shape of a zigzag ring structure formed by the same spiral lines as the first stator 3 and the second stator 4. The outer radius is R and the inner radius is R. The contact surfaces of the two rotors 2 and the stator contact surfaces of the first stator 3 and the second stator 4 can be coincidently matched. The rotor 2 is provided with screw holes penetrating through the thick wall so as to be connected and fixed with the rotor 2 sleeve 1 through hollow bolts 5

The rotor sleeve 1: the rotor sleeve 1 is a steel pipe with an inner hole provided with a spline groove. The external radius is r, and the hole is through setting up internal spline and the cooperation of pivot 7, and the external diameter leaves the bolt hole with 2 internal diameter cooperations of rotor to fixed rotor 2.

A rotating shaft 7: the rotating shaft 7 is connected with the rotor sleeve 1 through an external spline and is used for power output.

In addition to the above six major components, the present invention also has other accessory components for normal operation of the internal combustion engine, mainly including a water cooling jacket 16, a first end cap 17, a second end cap 18, an intake pipe 23, an exhaust pipe 24, a bearing 20, etc.

And secondly, the installation and arrangement of the components.

As shown in fig. 1, the rotor sleeve 1 is first sleeved with the first stator 3 with the flat end facing outward. The rotor 2 is then slipped on. Since the curved surfaces of both ends of the rotor 2 are identical in shape, there is no direction difference. The rotor 2 is then secured to the rotor housing 1 with the hollow bolt 5 and ensuring that the run-out of the bolt does not block the sliding of the splines within the barrel. The cylinder jacket 8 is sleeved on the rotor 2 and pushed to the first stator 3 to ensure that the cylinder jacket is tightly combined with the mounting ring groove 27 of the first stator 3. And the flat end of the second stator 4 is outward sleeved on the rotor 2 sleeve 1 and tightly pressed with the cylinder jacket 8. The phase difference of the two stator curved surfaces is 90 degrees.

The above operations are completed to form a cylindrical whole body consisting of the cylinder jacket 8, the first stator 3, the second stator 4, and the rotor housing 1 with the rotor 2 fixed therebetween. And two cavities facing 180 deg. are formed between the cylinder jacket 8 and the rotor housing 1, in which cavities the rotor 2 can rotate around the central axis and slide axially together with the rotor housing 1.

This six-piece construction, with a cylindrical outer surface, is pushed into the central bore of the water jacket 16. And the air inlet hole 28 and the air outlet hole 29 on the water cooling jacket 16 are arranged opposite to the air vent hole 9 of the cylinder jacket 8. The rotating shaft 7, which has been sleeved with the bearing 20, is advanced along the splines into the rotor housing 1. The first end cap 17 and the second end cap 18 are then added, and it is noted that the positions of the water-cooled channels 19 and the spark plugs of the first end cap 17 and the second end cap 18 are kept in agreement with the positions on the first stator 3 and the second stator 4, respectively. After the air inlet pipe 23 and the exhaust pipe 24 are additionally arranged, the device is installed. The various sealing measures involved in the overall process and the requirements for sealing elements, tolerance fit of parts, etc. are not detailed. These problems can be solved by the actual manufacturing process.

As an internal combustion engine, the external attachment of the present invention further includes: a water pump and a heat exchanger thereof, a starting motor and a storage battery, an air inlet throttle valve and an oil pump, an exhaust pipeline and a silencer, a tail gas purification device and the like. If the automobile is driven, a mechanical device such as a gearbox and the like may be needed. These devices are not essential to the use of conventional internal combustion engines and are not in the subject of the present patent, and are therefore not listed and discussed. In discussing the principles of operation of the present invention, however, it has been assumed that the devices described above are present and operating properly.

And thirdly, forming equations of contact surfaces of the first stator 3, the second stator 4, the rotor 2 and the cylinder jacket 8 of the device.

The two ends of the rotor 2, the one end of the first stator 3 and the one end of the second stator 4 form a turn-back circular ring structure formed by a spiral line, specifically as shown in fig. 6, the contact surfaces of the first stator 3, the rotor 2, the second stator 4 and the rotor 2, which are attached to each other, are equivalent to a cylinder with an inner diameter of 2R and an outer diameter of 2R, under the condition that the lead is +/-the lead, an arc curved surface formed by 90 degrees as an inflection point is used, and the expression mode is as follows:

the inner arcs x = r × cos (θ), y = r × sin (θ), z = (±) × θ.

The outer arcs x = R × cos (θ), y = R × sin (θ), z = (±) × θ (90 ° turn).

Wherein, theta is a variable of the rotation angle, and the lead can be selected according to different requirements. The principle is that the included angle a between two cambered surfaces is not less than 90 degrees. Since the curved surfaces of the contact surfaces of the first stator 3, the second stator 4, the rotor 2 and the cylinder sleeve are all completed by using the same cylindrical polar coordinate equation, the curved surfaces of the first stator, the second stator, the rotor and the cylinder sleeve are completely overlapped without gaps after the arrangement of the same axis is arranged (the machining error is not considered).

Fourthly, the working principle related to the invention.

As shown in fig. 8, the two parts of the figure indicate that two cavities are partitioned by two stators and the cylinder sleeve and the inner sleeve of the rotor 2 respectively. As shown in fig. 8, in the process of the movement of the rotor 2, two cavities (cylinders) separated in the whole circumferential direction by the first stator 3 and the second stator 4 are divided into four sub-cavities a \ B \ C \ D. Wherein each cavity functions as:

a-suction, B-compression, C-explosion and D-exhaust.

Respectively 4 work processes of the four-stroke internal combustion engine. The energy required by the three processes of exhaust, suction and compression is provided by the explosion process. After the rotor 2 is rotated by 90 ° in the circumferential direction, the above four processes are ended. The separate chambers in the cylinder begin to function in the transition, as in fig. 8 (c):

b-suction, A-compression, D-explosion and C-exhaust.

Wherein the A-B space functions are transformed into each other and the C-D space functions are transformed into each other. Different from the traditional four-stroke internal combustion engine, the four functions of air suction, compression, explosion and exhaust in the same cylinder are required to be completed respectively to form a working cycle. In the device, the stator surrounds two cavities formed by the circumference, one of the two cavities can always complete the functions of explosion and exhaust, and the device can be called a hot cylinder. Labeled C and D in fig. 8. The other chamber always performs the suction-compression function and can be called a cold cylinder. Labeled as a and B in fig. 8. Under the push of the rotor 2 in the two alternative explosions in the C, D cavities in the hot cylinder, each explosion completes the 90-degree rotation around the axis in the circumferential direction and the sliding along the axis, so as to push the piston rotor 2 to rotate around the axis ceaselessly and output energy. Similar to the alternating movement of the left and right feet when a person walks, the purpose of moving towards a certain direction is achieved. This is also the origin of the "stepping" in the name of the device. In order to complete the entire cycle, the rotor 2 (piston) has a special design of the compressed gas ducts 15, which ensures this function, and the compressed gas ducts 15 are distributed over the curved surfaces (contact surfaces) of the rotor 2 on both sides in the radial direction of symmetry.

Fifthly, lubricating, sealing, air intake and air exhaust.

The main lubrication surfaces of the present invention are the self-established rotating and sliding friction surfaces of the rotor 2 and the cylinder jacket 8 and the sliding friction surfaces between the first stator 3, the second stator 4 and the rotor 2. Fig. 12 specifically shows a hollow bolt 5 with a central hole for fixing the rotor 2, and fig. 1 shows the installation position of the hollow bolt 5. When the rotor 2 is operating, the centrifugal force of rotation throws the lubricant in the oil chamber through these small holes into the friction surfaces between the rotor 2 and the cylinder jacket 8, as shown in fig. 1, and is lubricated by the axial sliding of the rotor 2. The lubrication of the rotor sleeve 1, the inner holes of the first stator 3 and the second stator 4 is completed by the back-and-forth movement of the rotor sleeve 1, the inner holes of the first stator 3 and the inner holes of the second stator 4. During the back and forth movement, oil is remained on the friction surfaces of the first stator 3 and the rotor 2, and the second stator 4 and the rotor 2 to play a role in lubrication.

In the operation process of the invention, the rotor 2, the first stator 3, the second stator 4, the rotor 2 sleeve 1 and the cylinder outer sleeve 8 are sealed to stably work. The positions of the seal rings (rotor seal ring 21, rotor sleeve seal ring 22) at various positions are shown in fig. 1. They are all arranged along the entire circumference. The only difference from the conventional piston ring for internal combustion engines is that in the circumferential direction, the rings are of a broken line structure, and are otherwise identical. Between the rotor 2 and the first stator 3, and between the rotor 2 and the second stator 4, because a twisted surface is not suitable for sealing with a sealing ring, a tesla valve structure 14 is designed, as shown in fig. 7, and fine grooves are formed on the contact surface of the first stator 3 and the rotor 2, and the contact surface of the second stator 4 and the rotor 2. The structure can reduce the overflow of gas to the maximum extent and play a role in one-way gas sealing.

The air intake and exhaust functions of the device of the invention are realized by the relative positions of the rotor 2 and the first stator 3 and the second stator 4, a cam system such as a valve is not needed, and the principle is shown in fig. 9 and 10. In the diagram (r) in fig. 9, the rotor 2 is moved in the direction of the arrow. Before the first boundary 34 and the second boundary 35 are not in contact, the gas hole armor 30 is covered by the rotor 2 itself (the gas hole is opened on the cylinder jacket 8) and the a gas chamber is completing the compression stroke, and the gas is compressed without any leakage. Meanwhile, the air holes B31 of the adjacent B air chambers are in an open state, and the air suction process is completed until the first boundary 34 and the second boundary 35 are contacted. In the diagram of fig. 9, when the air chamber a completes the compression process, the rotor 2 moves in the direction of the arrow, the air hole B31 is blocked, the air chamber B starts to enter the compression stroke, and the air chamber a sucks air through the air hole a 30 until the third boundary 36 and the fourth boundary 37 contact. In the air intake compression link, the function of the valve distribution system of the traditional internal combustion engine can be completed only by reasonably designing the positions and the shapes of the air holes A and B. The explosion and exhaust functions are alternately performed in the air chambers C and D respectively, as shown in the diagrams (i) and (ii) in FIG. 10, the air path conditions of two strokes of explosion and exhaust are given, and the principle is the same as the principle of air intake compression.

Sixthly, ignition process.

As shown in fig. 11, during the movement of the rotor 2, the compressed air passage 15 of the rotor 2 is alternately communicated with the ignition holes 13 of the first stator 3 and the second stator 4. As the rotor 2 piston moves, the oil and gas in the chamber a is forced into the ignition hole 13 of the stator. There are spark plug discharge electrodes mounted on the first stator 3 and the second stator 4. Once the movement of the rotor 2 reaches the ignition condition (as measured by the spindle position encoder), an explosion stroke can be entered. And the contact surfaces of the rotor 2 with the first stator 3 and the second stator 4 are sealed by the tesla valve structure 14.
