Abstract
Description
Technical Field
[0001] This application relates to the field of compressor technology, specifically to a cylinder assembly for a compressor and a compressor. Background Technology
[0002] Currently, in roller compressors, the crankshaft drives rollers to roll within the working chamber of the cylinder. Sliding vanes are slidably positioned within vane grooves that communicate with the working chamber. The heads of the vanes contact the outer wall of the rollers, dividing the working chamber into an intake chamber and an exhaust chamber. During compressor operation, the vanes are subjected to gas pressure within the working chamber, causing friction against the inner wall of the vane groove, resulting in vane wear.
[0003] To reduce the wear of the sliding vane, a compression mechanism is disclosed in the related technology. The compression mechanism includes a cylinder, a roller, a sliding vane, and a pressure channel. The cylinder has a cylinder cavity, a sliding vane groove, and an intake port and an exhaust port located on both sides of the sliding vane groove. One end of the sliding vane groove adjacent to the outer wall of the cylinder is closed. The roller is eccentrically rotatably disposed in the cylinder cavity. The sliding vane is reciprocally slidably disposed in the sliding vane groove. The head of the sliding vane abuts against the outer wall of the roller, and the tail of the sliding vane is provided with an elastic element abutting against the rear end wall of the sliding vane groove. One end of the pressure channel is connected to the cylinder cavity on the exhaust port side, and the other end of the pressure channel is connected to the sliding vane groove on the tail side of the sliding vane.
[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:
[0005] In related technologies, although the wear of the vane can be reduced by setting an elastic element between the tail end of the vane and the rear end wall of the vane groove, and by setting a pressure groove, the stability of the elastic element is relatively weak, which can easily affect the motion stability of the vane. This can cause the vane to separate from the outer wall surface of the roller, thereby compromising the sealing of the working chamber and affecting the compression efficiency of the compressor.
[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0014] Optionally, the slider further includes: a slider body portion connected to the side of the slider tail portion facing the working cavity, wherein the cross-sectional area of the slider tail portion is larger than the cross-sectional area of the slider body portion.
[0015] Optionally, the slider groove includes a connected sliding cavity and a reset cavity. The main body of the slider moves in the sliding cavity, and the tail of the slider and the elastic component are disposed in the reset cavity. The cross-sectional area of the reset cavity is larger than the cross-sectional area of the sliding cavity, and the cross-sectional area of the tail of the slider is larger than the cross-sectional area of the sliding cavity. When the tail of the slider moves toward the working cavity, it can abut against the front cavity wall of the reset cavity for limitation.
[0016] Optionally, when the slider moves from the slider groove toward the working cavity to its maximum displacement, the elastic element is in a free state.
[0017] Optionally, the cylinder is provided with a channel that connects an external gas source and a sliding vane groove. The airflow from the external gas source enters the sliding vane groove through the channel so that the airflow can push the sliding vane toward the working chamber.

[0019] The cylinder assembly and compressor for a compressor provided in this disclosure can achieve the following technical effects:
[0020] By incorporating multiple elastic elements between the tail end of the vane and the rear wall of the vane groove, the expansion and contraction of these elements provide driving force to the vane, creating multi-point elastic support and improving its motion stability. The multiple elastic elements are arranged circumferentially along the end face of the vane tail, ensuring balanced elastic support in all directions. This effectively prevents vane misalignment that might occur with single-point elastic support, thus improving the uniformity of force distribution during movement. This also allows the vane head to maintain a more stable and tight fit against the outer wall of the compressor rollers, ensuring a good seal between the intake and exhaust chambers.

[0047] Currently, in roller compressors, the crankshaft drives rollers to roll within the working chamber of the cylinder. Sliding vanes are slidably positioned within vane grooves that communicate with the working chamber. The heads of the vanes contact the outer wall of the rollers, dividing the working chamber into an intake chamber and an exhaust chamber. During compressor operation, the vanes are subjected to gas pressure within the working chamber, causing friction against the inner wall of the vane groove, resulting in vane wear.
[0048] To reduce the wear of the sliding vane, a compression mechanism is disclosed in the related technology. The compression mechanism includes a cylinder, a roller, a sliding vane, and a pressure channel. The cylinder has a cylinder cavity, a sliding vane groove, and an intake port and an exhaust port located on both sides of the sliding vane groove. One end of the sliding vane groove adjacent to the outer wall of the cylinder is closed. The roller is eccentrically rotatably disposed in the cylinder cavity. The sliding vane is reciprocally slidably disposed in the sliding vane groove. The head of the sliding vane abuts against the outer wall of the roller, and the tail of the sliding vane is provided with an elastic element abutting against the rear end wall of the sliding vane groove. One end of the pressure channel is connected to the cylinder cavity on the exhaust port side, and the other end of the pressure channel is connected to the sliding vane groove on the tail side of the sliding vane.
[0049] In related technologies, although the wear of the vane can be reduced by setting an elastic element between the tail end of the vane and the rear end wall of the vane groove, and by setting a pressure groove, the stability of the elastic element is relatively weak, which can easily affect the motion stability of the vane. This can cause the vane to separate from the outer wall surface of the roller, thereby compromising the sealing of the working chamber and affecting the compression efficiency of the compressor.
[0050] Combination Figure 1-10 As shown, this disclosure provides a cylinder assembly 102 for a compressor 10, including a cylinder 20, a vane 30, and an elastic component 60.
[0051] The cylinder 20 is provided with a sliding vane groove 22 and a working chamber 23; the sliding vane 30 is movably disposed in the sliding vane groove 22, and the sliding vane 30 includes a sliding vane tail 34, which faces the rear groove wall 223 of the sliding vane groove 22; the elastic component 60 is disposed between the sliding vane tail 34 and the rear groove wall 223 of the sliding vane groove 22, and the elastic component 60 includes a plurality of elastic elements 61, which are arranged circumferentially along the end face of the sliding vane tail 34.
[0052] The cylinder assembly 102 for the compressor 10 provided in this embodiment of the present disclosure utilizes a plurality of elastic elements 61 disposed between the tail 34 of the vane and the rear groove wall 223 of the vane groove 22. The expansion and contraction of the elastic elements 61 provide driving force to the vane 30, forming multi-point elastic support for the vane 30, thereby improving the motion stability of the vane 30. The plurality of elastic elements 61 are arranged circumferentially along the end face of the tail 34 of the vane, ensuring that the vane 30 receives balanced elastic support in all directions. This effectively avoids the vane 30 from tilting due to single-point elastic support, thus improving the uniformity of force on the vane 30 during movement. This allows the head of the vane 30 to maintain a more stable and tight fit with the outer wall surface 41 of the roller 40 of the compressor 10, thereby maintaining good sealing between the intake and exhaust chambers and improving the compression efficiency of the compressor. Furthermore, the arrangement of multiple elastic elements 61 can enhance the overall stability of the elastic component 60. Multiple elastic elements 61 can share the force, reducing the risk of decreased motion stability caused by abnormality or lifespan issues of a single elastic element 61.
[0053] Optionally, combined Figure 1-4 As shown, multiple elastic elements 61 are evenly distributed circumferentially along the end face of the tail of the slide plate 34.
[0054] This ensures that the elastic force on the slide 30 is uniform and consistent at all circumferential positions, effectively preventing the slide 30 from tilting within the slide groove 22 and ensuring good contact between the slide 30 and the outer wall surface 41 of the roller 40. Simultaneously, this also avoids fatigue damage to the slide 30 and elastic element 61 caused by uneven force distribution, extending the service life of the components.
[0055] Optionally, a plurality of elastic elements 61 are arranged symmetrically along the circumferential direction of the end face of the slide tail 34.
[0056] When the slider 30 is subjected to an external force, the reaction force generated by the elastic element 61 is symmetrically distributed circumferentially on the end face of the slider tail 34. This symmetrical force distribution helps the slider 30 maintain stability during movement, preventing the slider 30 from tilting due to excessive elastic force on one side and insufficient elastic force on the other, thus maintaining good contact between the slider 30 and the outer wall surface 41 of the roller 40. In addition, this can also reduce vibration and noise caused by asymmetrical force when the slider 30 slides.
[0057] Optionally, combined Figure 1-4 As shown, the elastic element 61 is a spring.
[0058] Springs provide stable elastic force, maintain performance during long-term compression and tension cycles, and absorb shocks and vibrations during the movement of slider 30, thereby improving the motion stability and service life of slider 30. It is understood that the elastic element 61 can also be an elastic structure such as elastic rubber or an elastic metal sheet. Elastic rubber has good elasticity and shock absorption properties. Elastic metal sheets have high elastic modulus and strength, and can withstand large loads.
[0059] Optionally, the number of elastic elements 61 is greater than or equal to 3.
[0060] This avoids the problem of uneven force distribution caused by the abnormality or failure of a single elastic element 61, and improves the stability of the elastic support function of the entire elastic assembly 60. It can be understood that the number of elastic elements 61 can be 3, 4, 5, 6, 7, 8, 9, or 10.
[0061] Optionally, combined Figure 2-5 As shown, the elastic component 60 also includes a guide plate 62, which is disposed between the elastic member 61 and the tail of the slider 34, and the first end of the elastic member 61 is connected to the guide plate 62.
[0062] During the reciprocating motion of the slider 30, the guide plate 62 can transmit the elastic force of multiple elastic elements 61 to the slider 30 more evenly and accurately, making the elastic force on the slider 30 more uniform and stable, thereby effectively enhancing the stability of the slider 30's motion.
[0063] Optionally, the circumferential direction of the guide plate 62 is consistent with the circumferential direction of the end face of the slider tail 34.
[0064] The guide plate 62 shares the same central axis as the slider 30, and the circumferential direction of the guide plate 62 is consistent with the circumferential direction of the end face of the slider tail 34. Multiple elastic elements 61 are arranged circumferentially along the end face of the slider tail 34, that is, multiple elastic elements 61 are arranged circumferentially along the guide plate 62. This allows the guide plate 62 to uniformly and stably receive and transmit the force of the multiple elastic elements 61, and effectively transmit it to the slider tail 34, so that the slider 30 can obtain uniform and stable elastic support during movement. It can be understood that elastic elements 61 can also be provided in the middle of the guide plate 62.
[0065] Optionally, combined Figure 4 , Figure 5 and Figure 7 As shown, the guide plate 62 is provided with a connecting part 621, and the slider tail 34 is provided with a connecting mating part 341. The connecting part 621 and the connecting mating part 341 cooperate to connect the guide plate 62 and the slider tail 34.
[0066] The guide plate 62 engages with the connecting part 341 of the slider tail 34 via the connecting part 621, achieving a stable and reliable connection between the two. This prevents the guide plate 62 from separating or loosening from the slider tail 34 during the reciprocating motion of the slider 30, ensuring that the guide plate 62 maintains a constant direction of motion. The connection between the guide plate 62 and the slider tail 34 also allows the elastic support force of the elastic component 60 to be transmitted more directly and efficiently to the slider 30, thereby improving the stability of the slider 30's movement.
[0067] Optionally, combined Figure 4 , Figure 5 and Figure 7 As shown, one of the connecting part 621 and the connecting mating part 341 is a limiting post 622 and the other is a limiting hole 342. The limiting post 622 is inserted into the limiting hole 342 to fix the guide plate 62 and the tail of the slide plate 34.
[0068] The guide plate 62 and the slider tail 34 are fixedly connected by the limiting post 622 engaging with the limiting hole 342. This connection structure has high connection strength and can effectively prevent relative displacement, loosening, or separation between the guide plate 62 and the slider tail 34. Simultaneously, after the limiting post 622 engages with the limiting hole 342, the degrees of freedom of the guide plate 62 in all directions are restricted, making the guide plate 62 and the slider 30 form a whole, enhancing the rigidity of the overall structure, and thus improving the motion stability of the slider 30. There can be one or more limiting posts 622, and correspondingly, there can also be one or more limiting holes 342. This application uses the connecting part 621 as the limiting post 622 and the connecting mating part 341 as the limiting hole 342 as an example.
[0069] Optionally, combined Figure 4 , Figure 5 and Figure 7 As shown, there are multiple limiting posts 622, which are evenly distributed on the guide plate 62; there are multiple limiting holes 342, which are evenly distributed on the tail of the slider 34, and each limiting hole 342 corresponds to a limiting post 622.
[0070] Multiple limiting posts 622 and multiple limiting holes 342 are arranged in a one-to-one correspondence and engage with each other, so that the guide plate 62 and the slider tail 34 are fixedly connected through multiple connection points, which can improve the connection stability between the guide plate 62 and the slider tail 34. At the same time, this allows the stress to be evenly distributed between the guide plate 62 and the slider tail 34, effectively avoiding stress concentration.
[0071] Optionally, the area of the guide plate 62 is greater than or equal to the area of the end face of the slider tail 34.
[0072] This allows the guide plate 62 to fully cover the end face of the slider tail 34, thereby transmitting force more effectively and providing stable support. Simultaneously, this effectively prevents localized stress concentration on the end face of the slider tail 34 during movement, thus improving the motion stability of the slider 30. Furthermore, the larger area of the guide plate 62 provides a greater range of action for the multiple elastic elements 61, enabling a more even distribution of elastic force.
[0073] Optionally, combined Figure 2-4 and Figure 6 As shown, the elastic component 60 also includes a thrust plate 63, which is disposed between the elastic member 61 and the rear groove wall 223 of the sliding groove 22, and the second end of the elastic member 61 is connected to the thrust plate 63.
[0074] The thrust plate 63 is located between the elastic element 61 and the rear groove wall 223 of the vane groove 22 and is connected to the second end of the elastic element 61. It effectively and evenly transmits the force on the elastic element 61 to the rear groove wall 223 of the vane groove 22, allowing multiple elastic elements 61 to undergo coordinated elastic deformation and generate stable elastic force. This also prevents damage to the rear groove wall 223 caused by localized stress concentration in the elastic element 61, thereby extending the service life of the cylinder 20. Simultaneously, the thrust plate 63 provides a stable support platform for the elastic element 61, enabling it to stably exert its elastic effect during operation and preventing performance degradation due to positional misalignment or uneven force. This provides more stable elastic support for the vane 30 during movement, allowing it to more smoothly engage with the roller 40, reducing impact and wear between the vane 30 and the roller 40, and improving the overall operational stability of the compressor 10. The elastic component 60 consists of a thrust plate 63, multiple elastic elements 61, and a guide plate 62. The multiple elastic elements 61 are arranged circumferentially between the guide plate 62 and the thrust plate 63 along the end face of the slide tail 34, which enables the elastic component 60 to smoothly transmit the force.
[0075] Optionally, the circumferential direction of the thrust plate 63 is consistent with the circumferential direction of the end face of the slide tail 34.
[0076] The thrust plate 63 shares the same central axis as the slide 30, and the circumferential direction of the thrust plate 63 is consistent with the circumferential direction of the end face of the slide tail 34. Multiple elastic elements 61 are arranged circumferentially along the end face of the slide tail 34, that is, multiple elastic elements 61 are arranged circumferentially along the thrust plate 63. This allows the thrust plate 63 to uniformly and stably receive and transmit the force of the multiple elastic elements 61, and effectively transmit it to the rear groove wall 223 of the slide groove 22. It can be understood that elastic elements 61 can also be provided in the middle of the thrust plate 63.
[0077] Optionally, the area of the thrust plate 63 is the same as the area of the guide plate 62.
[0078] This ensures that the thrust plate 63 and the guide plate 62 are matched in size, thereby enabling better transmission of the force of the multiple elastic elements 61 and providing stable support for the multiple elastic elements 61.
[0079] For example, both the guide plate 62 and the thrust plate 63 are circular, and multiple springs are evenly distributed and symmetrically arranged between the guide plate 62 and the thrust plate 63 along the circumference, with the two ends of the springs connected to the guide plate 62 and the thrust plate 63 respectively. The circular structure has good symmetry, so that the force transmission path of the elastic component 60 is symmetrical and uniform during the reciprocating motion of the slider 30. It can be understood that the guide plate 62 and the thrust plate 63 can also adopt other shapes such as rectangles to adapt to different space constraints of the slider groove 22.
[0080] Optionally, combined Figure 2 , Figure 4 and Figure 6 As shown, the thrust plate 63 is provided with a fixing part 631, and the rear groove wall 223 of the slide groove 22 is provided with a fixing mating part 224. The fixing part 631 and the fixing mating part 224 cooperate to fix the thrust plate 63 to the rear groove wall 223 of the slide groove 22.
[0081] The thrust plate 63 is fixedly connected to the rear groove wall 223 of the vane groove 22 via the fixing part 631 and the fixing fit part 224, providing a stable support foundation for the elastic element 61. This effectively prevents the thrust plate 63 from shifting or loosening under the reaction force of the elastic element 61. The cooperation of the fixing boss 632 and the fastening hole 225 ensures that the thrust plate 63 fits tightly against the rear groove wall 223 of the vane groove 22, avoiding vibration and noise caused by the loosening of the thrust plate 63 and improving the smoothness of the compressor 10 operation. Through the stable connection between the thrust plate 63 and the vane groove 22, the elastic element 61 can function stably throughout the entire working process, thereby maintaining good contact between the vane 30 and the outer wall surface 41 of the roller 40.
[0082] Optionally, combined Figure 3 and Figure 6 As shown, one of the fixing part 631 and the fixing mating part 224 is a fixing boss 632 and the other is a fastening hole 225. The fixing boss 632 is inserted into the fastening hole 225 to fix the thrust plate 63 to the rear groove wall 223 of the slide groove 22.
[0083] The thrust plate 63 can be fixed to the rear wall 223 of the vane groove 22 by engaging the fixing boss 632 with the fastening hole 225, thus achieving a stable connection between the thrust plate 63 and the rear wall 223 of the vane groove 22. During the operation of the compressor 10, the elastic force generated by the elastic element 61 is transmitted to the rear wall 223 of the vane groove 22 through the thrust plate 63. This stable connection can withstand a large elastic reaction force, preventing the thrust plate 63 from loosening or shifting, and ensuring the stable transmission of the elastic force of the elastic element 61. The number of fixing bosses 632 can be one or more, and correspondingly, the number of fastening holes 225 can also be one or more. This application takes one fixing boss 632 as an example.
[0084] Optionally, combined Figure 7 As shown, the slider 30 also includes a slider body 35, which is connected to the side of the slider tail 34 facing the working cavity 23. The cross-sectional area of the slider tail 34 is larger than the cross-sectional area of the slider body 35.
[0085] The cross-sectional area of the slider tail 34 is larger than that of the slider body 35, which improves the structural stability and stress performance of the slider 30. During the reciprocating motion of the slider 30, the larger cross-sectional area of the slider tail 34 can withstand greater elastic force and gas pressure, enabling the elastic component 60 to effectively push the slider 30 towards the working chamber 23. It also better resists the lateral forces experienced by the slider 30 during its movement, preventing the slider 30 from tilting or jamming within the slider groove 22. Furthermore, the larger cross-sectional area of the slider tail 34 and the elastic component 60 also increases the contact area, allowing the elastic force to be distributed more evenly across the slider tail 34, reducing local stress concentration and extending the service life of the slider 30.
[0086] Optionally, combined Figure 8 As shown, the slider groove 22 includes a connected sliding cavity 226 and a reset cavity 227. The slider body 35 moves in the sliding cavity 226, and the slider tail 34 and the elastic component 60 are disposed in the reset cavity 227. The cross-sectional area of the reset cavity 227 is larger than the cross-sectional area of the sliding cavity 226, and the cross-sectional area of the slider tail 34 is larger than the cross-sectional area of the sliding cavity 226. When the slider tail 34 moves toward the working cavity 23, it can abut against the front cavity wall of the reset cavity 227 for limitation.
[0087] The cross-sectional area of the slider tail 34 is larger than that of the slider body 35, and the cross-sectional area of the reset cavity 227 is larger than that of the sliding cavity 226. This ensures that the cross-sectional area of the reset cavity 227 matches the cross-sectional area of the slider tail 34, and the cross-sectional area of the sliding cavity 226 matches the cross-sectional area of the slider body 35. When the slider 30 moves within the slider groove 22, the slider tail 34 can move smoothly within the reset cavity 227 without being obstructed due to insufficient space. Since the cross-sectional area of the slider tail 34 is larger than that of the sliding cavity 226, when the slider 30 moves from the slider groove 22 towards the working cavity 23 to its maximum displacement, the slider tail 34 moves towards the working cavity 23 to its limit position, where it abuts against the front wall of the reset cavity 227 for limitation. This effectively prevents the vane 30 from extending excessively out of the vane groove 22, thereby avoiding excessive compression or collision between the head of the vane 30 and the roller 40, and preventing damage to the vane 30 and the roller 40. Simultaneously, the larger space of the reset chamber 227 provides sufficient installation and movement space for the elastic component 60, ensuring that the elastic element 61 can properly perform its elastic function, providing stable elastic support for the vane 30, and enabling the vane 30 to maintain good sealing and movement stability during operation, thus improving the compression efficiency and operational stability of the compressor 10.
[0088] Optionally, combined Figure 7 As shown, the tail portion 34 of the slider protrudes to both sides of the slider body portion 35 along the width direction of the slider body portion 35.
[0089] The width direction of the slider body 35 is as follows Figure 7 As indicated by the middle arrow, the slider tail 34 protrudes to both sides of the slider body 35 along the width direction, forming a T-shaped structure or a similar T-shaped structure, which improves the operational balance of the slider 30. The slider body 35 is located within the sliding cavity 226, and the protruding sides of the slider tail 34 can abut against and limit the movement of the slider 30 against the front cavity wall of the reset cavity 227 located on both sides of the sliding cavity 226, preventing the slider 30 from shifting, thereby improving the balance and stability of the slider 30's movement.
[0090] Optionally, combined Figure 2 As shown, when the slider 30 moves from the slider groove 22 toward the working cavity 23 to its maximum displacement, the elastic element 61 is in a free state.
[0091] During the operation of the compressor 10, when the roller 40 is in its maximum motion trajectory, the vane 30 moves from the vane groove 22 toward the working chamber 23 to its maximum displacement. At this time, combined with Figure 2 As shown, the elastic element 61 is in a free state, neither stretched nor compressed, and is at its natural length, thus not generating additional elastic force on the slide 30. This avoids the elastic element 61 forming resistance as the slide 30 moves towards the working chamber 23, and also ensures that the slide 30 maintains appropriate contact pressure with the outer wall surface 41 of the roller 40, achieving good sealing between the intake and exhaust chambers and reducing wear between the slide 30 and the roller 40. Figure 3 As shown, when the sliding vane 30 moves to a position less than its maximum displacement, the elastic element 61 is compressed, generating a reaction force on the sliding vane 30 and forming an elastic support. This elastic support allows the sliding vane 30 and the roller 40 to maintain a tight fit, thereby maintaining the sealing effect of the working chamber 23 during the operation of the compressor 10.
[0092] Optionally, combined Figure 9 As shown, the cylinder 20 is provided with a channel 21, which connects an external gas source and a sliding vane groove 22. The airflow from the external gas source enters the sliding vane groove 22 through the channel 21, so that the airflow can push the sliding vane 30 toward the working chamber 23.
[0093] The airflow pressure from an external gas source provides additional driving force to the slider 30, which works in conjunction with the elastic force of the elastic element 61 to jointly drive the slider 30 to move. Even if part of the elastic element 61 fails, the airflow pressure can compensate for the corresponding force, thereby enhancing the stability of the slider 30's movement. The airflow direction is as follows: Figure 9 The direction indicated by the middle arrow.
[0094] Optionally, combined Figure 9As shown, the outlet of channel 21 is located between the rear groove wall 223 of the slide groove 22 and the tail of the slide 34.
[0095] After the airflow enters the slider groove 22 through the outlet, it can directly act on the slider tail 34 and provide a driving force to the slider tail 34. This allows the airflow to act on the slider 30 more precisely, enhancing the driving effect of the airflow.
