As shown in fig. 1 to 10, a cylinder assembly 100 according to an embodiment of the present invention includes a cylinder block 1, a valve assembly 2, a cylinder head 3, a gland 5, and a muffler 8.

The valve component 2 is arranged in the cylinder body 1, and a sealing ring 4 is arranged between the cylinder cover 3 and the valve component 2. The muffler 8 is integrally injection-molded with the cylinder head 3. The gland 5 is connected with the cylinder body 1, and the cylinder cover 3 is positioned between the cylinder body 1 and the gland 5, so that the gland 5 fixes the cylinder cover 3 on the cylinder body 1, namely, the cylinder cover 3 is clamped between the cylinder body 1 and the gland 5.

According to the cylinder assembly 100 of the embodiment of the invention, the silencer 8 and the cylinder cover 3 are integrally injection molded, so that the number of parts of the cylinder assembly 100 can be reduced, and the manufacturing difficulty and the manufacturing cost of the cylinder assembly 100 can be reduced.

But if the plastic-made cylinder head 3 is mounted on the cylinder block 1 using fasteners, such as screws or bolts, the cylinder head 3 may be deformed or even damaged. The cylinder assembly 100 according to the embodiment of the present invention can greatly reduce the stress of the cylinder head 3 by fixing the cylinder head 3 to the cylinder block 1 using the gland 5, so as to prevent the cylinder head 3 from being deformed or even damaged.

Further, the cylinder assembly 100 according to the embodiment of the present invention provides the seal ring 4 having excellent sealing performance between the cylinder head 3 and the valve assembly 2, so that the gland 5 needs to apply a small pressure to seal the valve assembly 2. Therefore, the acting force of the gland 5 on the cylinder body 1 can be greatly reduced, the cylinder body 1 can be prevented from deforming, and the normal operation of the cylinder assembly 100 and the compressor can be ensured.

Therefore, the cylinder assembly 100 according to the embodiment of the present invention has the advantages of good sealing effect, small number of parts, low manufacturing difficulty and cost, no deformation of the cylinder head 3 and the cylinder block 1, and the like.

As shown in fig. 1 to 10, the cylinder assembly 100 includes a cylinder block 1, a valve assembly 2, a cylinder head 3, a gland 5, and an elastic member 6. One end of the cylinder block 1 has a counterbore 11 and the valve assembly 2 is disposed in the counterbore 11.

The elastic piece 6 is annular, the elastic piece 6 is arranged between the cylinder cover 3 and the gland 5, and the elastic piece 6 is in a compressed state. In other words, the elastic member 6 is sandwiched between the cylinder head 3 and the gland 5. Alternatively, the elastic member 6 is a disc spring.

By arranging the annular elastic piece 6 between the cylinder cover 3 and the gland 5, the pressure applied by the gland 5 can be uniformly transmitted to the cylinder cover 3 through the elastic piece 6, and then the cylinder cover 3 can press the sealing ring 4 on the valve component 2, so that the sealing effect is further improved.

As shown in fig. 2 and 4, cylinder assembly 100 may further include a valve plate gasket 7, valve plate gasket 7 being disposed between bottom wall surface 113 of counterbore 11 and valve assembly 2. The bottom wall surface 113 of the counterbore 11 is the wall surface of the counterbore 11 opposite its opening. This can further improve the sealing performance of the valve assembly 2.

As shown in fig. 2, 4 and 5, one of the first positioning protrusion 111 and the positioning groove 21 is provided on the peripheral wall surface 112 of the counterbore 11, the other of the first positioning protrusion 111 and the positioning groove 21 is provided on the peripheral surfaces of the valve plate gasket 7 and the valve assembly 2, and the first positioning protrusion 111 is fitted in the positioning groove 21. Therefore, the positioning difficulty of the valve plate gasket 7 and the valve assembly 2 can be reduced, and the positioning precision of the valve plate gasket 7 and the valve assembly 2 can be improved.

Optionally, the peripheral wall surface 112 of the counterbore 11 is provided with a first positioning protrusion 111 to avoid reducing the structural strength of the cylinder block 1.

As shown in fig. 9, the seal ring 4 includes an annular portion 41 and a partition portion 42, the partition portion 42 having a first end portion 43 and a second end portion 44, each of the first end portion 43 and the second end portion 44 being connected to an inner edge of the annular portion 41 so as to partition an inner space of the annular portion 41 into two parts. The suction side and the discharge side of valve assembly 2 can thereby be effectively separated, resulting in a better sealing performance of cylinder assembly 100. Optionally, the divider 42 is L-shaped.

As shown in fig. 10, the cylinder head 3 is provided with a receiving groove 31, and a part of the gasket 4 is disposed in the receiving groove 31. Therefore, the sealing ring 4 can be more stably installed, large deformation of the sealing ring 4 in the radial direction of the sealing ring 4 under the extrusion of the cylinder cover 3 and the valve assembly 2 is avoided, namely, large displacement of at least one part of the sealing ring 4 in the radial direction of the sealing ring 4 under the extrusion of the cylinder cover 3 and the valve assembly 2 is avoided, and the sealing effect can be further improved.

As shown in fig. 9 and 10, one of the second positioning protrusion 45 and the positioning hole 32 is provided on the seal ring 4, the other of the second positioning protrusion 45 and the positioning hole 32 is provided on the cylinder head 3, and the second positioning protrusion 45 is provided in the positioning hole 32.

As shown in fig. 9, the seal ring 4 further includes a positioning portion 46. The positioning portion 46 is provided on the inner edge of the annular portion 41, and the positioning portion 46 extends from the inner edge of the annular portion 41 toward the center of the annular portion 41. Alternatively, the positioning portion 46 may extend in the radial direction of the annular portion 41 (seal ring 4). The positioning portion 46 is provided with one of the second positioning projection 45 and the positioning hole 32. The structure of the sealing ring 4 can thereby be made more rational.

Optionally, the positioning portion 46 is provided with a second positioning protrusion 45, and the cylinder head 3 is provided with a positioning hole 32. The seal ring 4 may be integrally injection molded from rubber.

As shown in fig. 1, 2, 5 and 6, the cylinder block 1 is provided with a first mounting portion 12 and a second mounting portion 13, and alternatively, the cylinder block 1, the first mounting portion 12 and the second mounting portion 13 may be integrally formed, for example, the cylinder block 1, the first mounting portion 12 and the second mounting portion 13 may be integrally formed by sintering.

The gland 5 includes a cover 51, a third mounting portion 52, and a fourth mounting portion 53, and the third mounting portion 52 and the fourth mounting portion 53 are connected to the cover 51. Wherein the cover body 51 abuts against the elastic member 6, i.e. the elastic member 6 is clamped between the cylinder head 3 and the cover body 51. The third mounting portion 52 is connected to the first mounting portion 12 by a fastener 9, and the fourth mounting portion 53 is connected to the second mounting portion 13 by a fastener 9, so that the cover 51 can abut (press) against the elastic member 6.

Because the sealing ring 4 has good sealing effect, the fastening piece 9 only needs to have small torque to realize the sealing of the valve component 2. Therefore, the cylinder body 1 can be prevented from being deformed, and the cylinder assembly 100 and the compressor can be ensured to normally operate.

Alternatively, as shown in fig. 1, 2 and 6, each of the third and fourth mounting portions 52 and 53 is L-shaped, the vertical portion 522 of the third mounting portion 52 and the vertical portion 532 of the fourth mounting portion 53 are connected to the cover 51, the horizontal portion 523 of the third mounting portion 52 is connected to the first mounting portion 12 by the fastener 9, and the horizontal portion 533 of the fourth mounting portion 53 is connected to the second mounting portion 13 by the fastener 9.

Specifically, the cover 51, the third mounting portion 52, and the fourth mounting portion 53 may be integrally formed, and the fastener 9 may be a screw or a bolt.

As shown in fig. 3, 4, 7 and 8, the cylinder block 1 is provided with a first protrusion and a second protrusion on the outer circumferential surface of one end thereof adjacent to the valve assembly 2, the gland 5 includes a cover body 51, a third mounting portion 52 and a fourth mounting portion 53, and the third mounting portion 52 and the fourth mounting portion 53 are connected to the cover body 51. The cover 51 abuts against the elastic member 6, the third mounting portion 52 is provided with a first buckle 521, the fourth mounting portion 53 is provided with a second buckle 531, the first buckle 521 is engaged with the first protrusion, and the second buckle 531 is engaged with the second protrusion. Whereby the gland 5 can be more conveniently and more easily mounted to the cylinder 1.

Alternatively, the first projection and the second projection are integrally formed as an annular flange 14, that is, the annular flange 14 is provided on the outer circumferential surface of the cylinder block 1. It is thus not necessary to mount the gland 5 to the cylinder 1 at a specific position, so that the gland 5 can be mounted to the cylinder 1 more conveniently and more easily. The flange 14 and the cylinder block 1 may be integrally formed, and the cover 51, the third mounting portion 52 and the fourth mounting portion 53 may be integrally formed.
