Description

Technical Field

[0001] This utility model relates to compressors, specifically providing a compressor gas supply component and a compressor. Background Technology

[0002] In existing technologies, compressors typically improve gas flow characteristics during operation by incorporating a gas injection structure, thereby enhancing overall energy efficiency and cooling / heating performance. Among these, a first valve plate with elastic deformation capability is widely used for gas injection control, automatically opening and closing by sensing the pressure difference between the gas injection channel and the compression chamber. However, when the pressure difference is large, the first valve plate is prone to excessive deformation, which may lead to fatigue damage over long-term operation. Simultaneously, when the pressure difference changes rapidly, the first valve plate may fail to return to its original position in time, causing seal failure and refrigerant backflow, affecting the stable operation and efficiency of the compressor.

[0003] Therefore, there is an urgent need in the field for a compressor injection component and a compressor to solve the above problems. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the first valve plate in the existing compressor is prone to excessive deformation and has difficulty in timely rebound, resulting in refrigerant backflow.

[0005] In a first aspect, the present invention provides a gas supply assembly for a compressor, the gas supply assembly comprising:

[0006] A sliding plate, wherein the sliding plate is provided with an exhaust port;

[0007] A first valve plate is disposed inside the slide plate. The first valve plate includes a deformable portion disposed at the exhaust port. The air pressure at the exhaust port can drive the deformable portion to deform.

[0008] The slide also includes a first lift limiting part disposed on the inner wall of the exhaust port. When the deformable part undergoes bending deformation, the first lift limiting part can limit the bending deformation range of the deformable part.

[0009] In a specific embodiment of the above-mentioned air replenishment component, the exhaust port is disposed on the surface of the sliding vane, and the first lift limiting part is disposed on the inner wall of the exhaust port.

[0010] In a specific embodiment of the above-mentioned air replenishment component, an angle is provided between the first lift limiting part and the outer wall of the slide where the first exhaust port is located, so that the first lift limiting part is inclined.

[0011] In a specific embodiment of the above-mentioned air replenishment component, a valve plate groove is provided in the sliding plate, the first valve plate is installed in the valve plate groove, and the valve plate groove is connected to the exhaust port.

[0012] In a specific embodiment of the above-mentioned air replenishment component, the sliding plate further includes an air replenishment groove that connects to the first exhaust port. In the initial state, the deformable part can block the air replenishment groove and the first exhaust port. When the air pressure in the air replenishment groove is greater than the air pressure at the first exhaust port, the deformable part can bend and deform to connect the air replenishment groove and the first exhaust port.

[0013] In a specific embodiment of the above-mentioned air replenishment component, the slide plate further includes a guide portion disposed on the inner wall of the exhaust port, and the guide portion and the first lift limiting portion are disposed on opposite sides of the inner wall of the exhaust port.

[0014] In a specific embodiment of the above-mentioned air replenishment component, the angle between the guide portion and the outer wall of the slide where the exhaust port is located is greater than the angle between the first lift limiting portion and the outer wall of the slide where the exhaust port is located.

[0015] In a second aspect, the present invention provides a compressor that includes the aforementioned gas replenishment component.

[0016] In a specific embodiment of the compressor described above, the compressor further includes a cylinder, an inner cavity is provided inside the cylinder, and a vane groove is provided on the inner wall of the inner cavity, with the vane movably disposed in the vane groove.

[0017] In a specific embodiment of the compressor described above, the compressor further includes rollers that are movably disposed in the inner cavity. The air supply assembly also includes an elastic element, one end of which is connected to the vane groove and the other end of which is connected to the vane, so that the vane abuts against the rollers.

[0018] In this invention, the first valve plate is disposed inside the sliding vane, allowing it to elastically deform under pressure to control exhaust. A lift limiting portion is provided on the inner wall of the exhaust port of the sliding vane. This effectively limits the deformation range of the first valve plate, preventing excessive deformation due to excessive pressure, thereby improving the stability and reliability of the gas replenishment control, preventing refrigerant backflow, and enhancing the overall operating performance of the compressor.

[0049] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0052] In existing vane-mounted air supply assemblies, the valve plate is typically connected to the vane via screws. However, due to the small size of the vane and valve plate, and the thin structure of the vane, screw connections not only require high precision in machining and assembly but also easily cause localized deformation of the vane, affecting the sealing performance and structural stability of the air supply assembly, thereby reducing the overall reliability of the compressor. To address the high process requirements and susceptibility to vane deformation in existing vane and valve plate connection structures, this embodiment discloses a compressor. (Refer to...) Figure 1 The compressor is specifically a twin-cylinder rotary compressor. It includes a main receiver 21, a refrigerant gas receiver 22, a housing 23, a motor 24, and a pump assembly 25. The main receiver 21 stores the main refrigerant required for system operation, ensuring normal liquid supply. The main receiver 21 is connected to the pump assembly 25. The structure of the main receiver 21 is the same as that in the prior art, and its specific structure will not be described further. The refrigerant gas receiver 22 stores refrigerant gas for replenishment. When the refrigerant gas in the pump assembly 25 is insufficient, it replenishes the gas through its connection to the pump assembly 25. The structure of the refrigerant gas receiver 22 is the same as that in the prior art, and its specific structure will not be described further. The housing 23 is located outside the pump assembly 25. The structure of the housing 23 is the same as that in the prior art, and its specific structure will not be described further. The motor 24 is used to drive the pump body assembly 25 to operate. The structure of the motor 24 is the same as that of the motor 24 in the prior art, and its specific structure will not be described in detail here.

[0053] Reference Figure 2 The pump body assembly 25 includes a crankshaft 301, an upper muffler 302, an inner muffler 303, a main bearing 304, an upper cylinder 305, a partition 306, a lower cylinder 307, a secondary bearing 308, a lower muffler 309, an upper roller 310, and a lower roller 311. A motor 24 is connected to the crankshaft 301 and can drive the crankshaft 301 to rotate. The upper muffler 302, inner muffler 303, main bearing 304, upper cylinder 305, partition 306, lower cylinder 307, secondary bearing 308, and lower muffler 309 are arranged sequentially along the length of the crankshaft 301. The upper cylinder 305 has an upper cylinder chamber 3051, and an upper roller 310 is disposed within the upper cylinder chamber 3051. The upper roller 310 is connected to a crankshaft 301, and the crankshaft 301 can drive the upper roller 310 to rotate within the upper cylinder chamber 3051. The lower cylinder 307 has a lower cylinder chamber, and a lower roller 311 is disposed within the lower cylinder chamber. The lower roller 311 is connected to a crankshaft 301, and the crankshaft 301 can drive the lower roller 311 to rotate within the lower cylinder chamber.

[0054] Furthermore, an upper sliding vane air supply assembly is installed in the upper cylinder 305, and a lower sliding vane air supply assembly is installed in the lower cylinder 307. The structures of the upper sliding vane air supply assembly and the lower sliding vane air supply assembly are basically the same. The following explanation will take the upper sliding vane air supply assembly as an example.

[0055] Reference Figure 3 The upper cylinder cavity 3051 is approximately cylindrical. A sliding vane groove 3052 is provided on the inner wall of the upper cylinder cavity 3051. The sliding vane groove 3052 extends outward from the upper cylinder 305. A spring hole 3053 is also provided on the upper cylinder 305, one end of which connects to the sliding vane groove 3052.

[0056] Reference Figure 2 and Figure 5 The upper sliding air supply assembly includes a sliding plate 11, an elastic element 13, and a first valve plate 12.

[0057] Reference Figure 4 The slider 11 has an approximate rectangular plate-like structure. (Refer to...) Figure 3 The shape of the slide groove 3052 matches the shape of the slide 11 so that the slide 11 can be installed in the slide groove 3052. The elastic element 13 is specifically a spring, one end of which is fixedly installed in the spring hole 3053, and the other end abuts against the first end of the slide 11. Further, the first end of the slide 11 is provided with a first groove 1105 and a second groove 1106, and a protrusion 1107 is formed between the first groove 1105 and the second groove 1106. The spring is sleeved on the protrusion 1107 so that the spring connects to the first end of the slide 11. The spring pushes the slide 11 so that the second end of the slide 11 extends into the upper cylinder cavity 3051 and remains in contact with the upper roller 310. In other words, when the upper roller 310 rotates in the upper cylinder 305, the spring pushes the slide 11 so that the slide 11 remains in contact with the upper roller 310. Furthermore, the upper roller 310 and the sliding vane 11 divide the upper cylinder cavity 3051 into two parts, namely the high-pressure side 30511 and the low-pressure side 30512, as detailed below. Figure 6 and Figure 7 .

[0058] Reference Figure 8 A refrigerant injection groove 1108 is provided on the side of the sliding vane 11 facing the partition 306. The refrigerant injection groove 1108 is used to receive refrigerant injected into the upward cylinder chamber 3051. (Refer to...) Figure 9 A first exhaust port 1109 is provided on the side of the second end of the sliding vane 11 facing the high-pressure side 30511. The first exhaust port 1109 is used to discharge the refrigerant in the air supply groove 1108 into the upper cylinder chamber 3051. See details. Figure 7 . Reference Figure 4 and Figure 8 The slide plate 11 is provided with a valve plate groove 1101, which is used to accommodate the first valve plate 12.

[0059] Reference Figure 5 The first valve plate 12 includes an integrally formed main body 121, a limiting part, and a connecting part 124.

[0060] The main body 121 has an approximate rectangular plate-like structure. This shape facilitates manufacturing and assembly, and meets the basic requirements for structural strength and spatial adaptability. (Refer to...) Figure 4 The shape of the valve plate groove 1101 matches the shape of the main body 121, that is, it is also an approximately rectangular cavity structure. This shape matching allows the main body 121 to be placed in the valve plate groove 1101 to position the first valve plate 12 radially and circumferentially. Furthermore, the main body 121 and the valve plate groove 1101 are set with a transition fit. This fit ensures the convenience of installation, that is, the main body 121 can be smoothly inserted into the valve plate groove 1101; on the other hand, it has a certain interference effect, which can enhance the firmness of the fit between the two, effectively preventing loosening or gap changes during operation, thereby ensuring that the first valve plate 12 can maintain an accurate opening and closing position and working state for a long time.

[0061] Reference Figure 5 A limiting portion is provided on the main body 121 near the first end of the slider 11. Specifically, a first limiting portion 122 and a second limiting portion 123 are respectively provided on both sides of the main body 121. In other words, the main body 121, the first limiting portion 122, and the second limiting portion 123 form a T-shaped structure. (Refer to...) Figure 4 The valve plate groove 1101 also includes a first limiting groove 1102 and a second limiting groove 1103. The shape of the first limiting groove 1102 matches the shape of the first limiting part 122. The first limiting groove 1102 has an opening at the bottom of the first groove 1105 so that the first limiting part 122 can extend into the first limiting groove 1102 through the opening. The shape of the second limiting groove 1103 matches the shape of the second limiting part 123. The second limiting groove 1103 has an opening at the bottom of the second groove 1106 so that the second limiting part 123 can extend into the second limiting groove 1103 through the opening.

[0062] Reference Figure 5 The connecting part 124 is located at the first end of the main body 121 near the slider 11. Specifically, the main body 121, the first limiting part 122, the second limiting part 123, and the connecting part 124 form a cross-shaped structure. (Refer to...) Figure 4 and Figure 8 The valve plate groove 1101 also includes a connecting groove 1104, the shape of which matches the shape of the connecting part 124, and the connecting part 124 is disposed at the connecting groove 1104. Further, the connecting groove 1104 has an opening at the first end of the slide plate 11, through which the main body 121 can extend into the valve plate groove 1101, and the connecting part 124 can also extend into the connecting groove 1104 through the opening. A spring is sleeved on the protrusion 1107 and also on the connecting part 124, so that the spring connects to the first valve plate 12.

[0063] Reference Figure 5 In this embodiment, the width of the first end of the connecting portion 124 is smaller than the width of the second end, and the first end is far away from the main body 121. Furthermore, the connecting portion 124 is trapezoidal in shape. This arrangement allows the spring to be engaged with the outside of the connecting portion 124, enabling the spring to push the first valve plate 12 towards the second end of the slide plate 11, so that the first limiting portion 122 abuts against the end face of the first limiting groove 1102 near the second end of the slide plate 11, and the second limiting portion 123 abuts against the end face of the second limiting groove 1103 near the second end of the slide plate 11, thereby achieving axial positioning of the first valve plate 12.

[0064] In another embodiment, the widths of the first limiting portion 122 and the second limiting portion 123 are greater than the width of the connecting portion 124. When the spring is sleeved outside the connecting portion 124, the end of the spring can abut against the first limiting portion 122 and the second limiting portion 123, so that the spring pushes the first limiting portion 122 to abut against the end face of the first limiting groove 1102 near the second end of the slide plate 11, and the second limiting portion 123 to abut against the end face of the second limiting groove 1103 near the second end of the slide plate 11, thereby achieving axial positioning of the first valve plate 12.

[0065] Compared to the existing technology that uses screws to fix the first valve plate 12 to the sliding plate 11, the mounting structure of this invention eliminates the need for threading or screw fastening on the sliding plate 11 and the first valve plate 12. This significantly simplifies the manufacturing process, reduces assembly difficulty, and minimizes uncertainties caused by assembly errors. Furthermore, this insert-type structure effectively avoids localized stress concentration in the sliding plate 11 caused by screw fastening, thereby reducing the risk of deformation of the sliding plate 11 during assembly or compressor operation. This contributes to improving the overall operational stability, reliability, and service life of the compressor. This structure not only optimizes product design but also brings higher efficiency and consistency to mass production.

[0066] Furthermore, referring to Figure 8 and Figure 9 The air supply groove 1108 and the first exhaust port 1109 are both connected to the valve plate groove 1101 near the second end of the sliding plate 11. Specifically, a channel 1110 is provided between the air supply groove 1108 and the valve plate groove 1101. The first exhaust port 1109 and the channel 1110 are respectively located on both sides of the valve plate groove 1101. (Refer to...) Figure 5 The first valve plate 12 also includes a deformable portion 125, which is disposed at the end of the main body 121. (See reference...) Figure 6When the first valve plate 12 is installed in the valve plate groove 1101, the deformable part 125 is positioned in the valve plate groove 1101 near the second end of the sliding plate 11, and the end of the deformable part 125 is spaced apart from the end of the valve plate groove 1101 to avoid affecting the deformation of the deformable part 125. In the initial state, the deformable part 125 isolates the first exhaust port 1109 and the channel 1110. (Refer to...) Figure 7 When the air pressure in the air supply groove 1108 is greater than the air pressure in the upper cylinder chamber 3051, the pressure difference will cause the deformable part 125 to bend and deform, so that the air supply groove 1108 connects to the first exhaust port 1109, and the refrigerant in the air supply groove 1108 can flow into the upper cylinder chamber 3051. Furthermore, the deformable part 125 of the first valve plate 12 is made of an elastic material so that the deformable part 125 can undergo elastic deformation.

[0067] Furthermore, referring to Figure 9 The valve plate groove 1101 includes a blocking portion 1111. When the deformable portion 125 is in its initial state, it fits against the blocking portion 1111 to close the channel 1110. Furthermore, when the air pressure in the upper cylinder chamber 3051 is greater than the air pressure in the air supply groove 1108, the deformable portion 125 is blocked by the blocking portion 1111 to prevent the head of the first valve plate 12 from deforming, causing the first exhaust port 1109 to communicate with the air supply groove 1108, thereby preventing the refrigerant in the upper cylinder chamber 3051 from flowing back into the air supply groove 1108.

[0068] Furthermore, the first exhaust port 1109 is provided with a first lift limiting part 1112, which is specifically disposed on the inner wall of the first exhaust port 1109 near the first end of the sliding vane 11. An angle is formed between the first lift limiting part 1112 and the outer wall of the sliding vane 11 where the first exhaust port 1109 is located, making the first lift limiting part 1112 inclined. When the air pressure in the air supply groove 1108 is greater than the air pressure in the upper cylinder chamber 3051, the pressure difference will drive the deformable part 125 to deform. The first lift limiting part 1112 will block the deformable part 125, thus limiting the bending deformation range of the deformable part 125. This arrangement can prevent the deformable part 125 from excessively deforming, thereby avoiding backflow problems caused by the deformable part 125's inability to return to its initial state in time after the pressure difference disappears.

[0069] Furthermore, the angle between the first lift limiting part 1112 and the outer wall of the sliding vane 11 where the first exhaust port 1109 is located is a first included angle α. A guide part is also provided at the first exhaust port 1109, and the guide part and the first lift limiting part 1112 are located on opposite sides of the inner wall of the first exhaust port 1109. The guide part can guide the flow of refrigerant discharged from the first exhaust port 1109. The angle between the guide part and the outer wall of the sliding vane 11 where the first exhaust port 1109 is located is a second included angle β. The angle between the channel 1110 and the outer wall of the sliding vane 11 where the first exhaust port 1109 is located is a third included angle β. The first included angle α is greater than 0 degrees and less than the third included angle β; the second included angle β is greater than the third included angle β and less than 90 degrees. This arrangement facilitates manufacturing.

[0070] Furthermore, referring to Figure 10 and Figure 11 A gas replenishment channel is provided on the partition 306. One end of the gas replenishment channel is connected to the gas replenishment reservoir 22, and the other end is connected to the gas replenishment groove 1108 of the sliding vane 11, so that the gas replenishment reservoir 22 delivers refrigerant to the gas replenishment groove 1108. Specifically, the gas replenishment channel includes an air inlet 41, a main flow channel 42, a first injection channel 43, and a second injection channel 44. The air inlet 41 is located on the outer wall of the partition 306 and is connected to the gas replenishment reservoir 22. One end of the main flow channel 42 is connected to the air inlet 41, and the other end extends into the partition 306. The first injection channel 43 and the second injection channel 44 are both connected to the main flow channel 42. The first injection channel 43 forms a first jet nozzle 45 on one side of the partition 306, and the second injection channel 44 forms a second jet nozzle 46 on the other side of the partition 306. In other words, the main flow channel 42, the first injection channel 43, and the second injection channel 44 form a Y-shaped structure. A partition 306 is disposed between the upper cylinder 305 and the lower cylinder 307. The first jet port 45 is connected to the air supply groove 1108 of the sliding vane 11 of the upper cylinder 305, and the second jet channel 44 is connected to the air supply groove 1108 of the sliding vane 11 of the lower cylinder 307. The structure of the first jet port 45 is basically the same as that of the second jet port 46. The following description uses the first jet port 45 as an example.

[0071] Reference Figure 12 Since the sliding vane 11 and the upper roller 310 divide the upper cylinder chamber 3051 into a high-pressure side 30511 and a low-pressure side 30512, the pressure difference between the high-pressure side 30511 and the low-pressure side 30512 will cause the sliding vane 11 to be subjected to thrust. Figure 12 F1 represents the thrust generated by the pressure difference. This thrust causes the slider 11 to move along... Figure 12 When the slider 11 deflects clockwise and moves along the slider groove 3052, it will cause accelerated wear between the slider 11 and the slider groove 3052. Specifically, Figure 12 E and F in the diagram represent areas of accelerated wear. (Refer to...) Figure 13The air supply groove 1108 of the sliding vane 11 has a rectangular shape and is located in the middle of the sliding vane 11. The direction of the first jet channel 43 and the direction of the first jet nozzle 45 are oriented towards the side wall of the air supply groove 1108 near the low-pressure side 30512. Figure 13 The middle arrow G indicates the direction of the first injection channel 43 and the direction of the first injection port 45. This arrangement allows the refrigerant flowing into the make-up air tank 1108 to generate thrust on the sliding vane 11. Figure 13 F2 represents the thrust. This thrust F2 forms a counter-torque with the air pressure difference thrust F1 in the upper cylinder chamber 3051, reducing the tilt of the vane 11, thereby reducing the wear between the vane 11 and the vane groove 3052, extending service life, and improving operational stability.

[0072] The working principle of the upper cylinder 305 of this compressor is as follows: (Refer to...) Figure 14 and Figure 15 When the compressor is in its first state, the length of the vane 11 extending out of the vane groove 3052 is at its minimum; in other words, the vane 11 is entirely located within the vane groove 3052. Simultaneously, the first exhaust port 1109 is covered by the side wall of the vane groove 3052, and the air pressure within the upper cylinder chamber 3051 does not affect the first valve plate 12. The first valve plate 12 isolates the air supply groove 1108 and the first exhaust port 1109. The crankshaft 301 drives the upper roller 310 to rotate, and the spring pushes the vane 11 from the vane groove 3052 into the upper cylinder chamber 3051. (Refer to...) Figure 16 and Figure 17 When the compressor is in the second state, the first exhaust port 1109 connects to the upper cylinder chamber 3051, causing the air pressure in the upper cylinder chamber 3051 to act on the deformed portion 125 of the first valve plate 12. The crankshaft 301 drives the upper roller 310 to continue rotating, causing the sliding vane 11 to continue extending into the upper cylinder chamber 3051. (Refer to...) Figure 18 and Figure 19 The compressor enters the third state, with the upper roller 310 at its furthest position from the vane groove 3052, and the vane 11 extending into the upper cylinder chamber 3051 to its maximum length. The crankshaft 301 drives the upper roller 310 to continue rotating, causing the vane 11 to retract into the vane groove 3052. (Refer to...) Figure 20 and Figure 21When the compressor reaches the fourth state, the first exhaust port 1109 is located at the edge of the vane groove 3052, and the first exhaust port 1109 is still connected to the upper cylinder chamber 3051. After the crankshaft 301 continues to rotate, the first exhaust port 1109 is retracted into the vane groove 3052, and the air pressure in the upper cylinder chamber 3051 does not affect the first valve plate 12. Between the second and fourth states, the first exhaust port 1109 is connected to the upper cylinder chamber 3051. When the air pressure in the upper cylinder chamber 3051 is greater than the air pressure in the air supply groove 1108, the deformed part 125 of the first valve plate 12 is in the initial state, isolating the first exhaust port 1109 from the air supply groove 1108, and the air supply groove 1108 does not supply air to the upper cylinder chamber 3051. When the air pressure in the upper cylinder chamber 3051 is less than the air pressure in the air replenishment groove 1108, the deformation part 125 deforms, so that the air replenishment groove 1108 is connected to the first exhaust port 1109, and the refrigerant in the air replenishment groove 1108 flows into the upper cylinder chamber 3051 to complete the air replenishment.

[0073] Furthermore, partition 306 also includes a partition air supply assembly. (See reference...) Figure 22 A first mounting groove 3061 is provided on the side of the partition 306 facing the upper cylinder 305, and a first partition air supply component is disposed in the first mounting groove 3061. A second mounting groove is provided on the side of the partition 306 facing the lower cylinder 307, and a second partition air supply component is disposed in the second mounting groove. The structure of the first partition air supply component is basically the same as that of the second partition air supply component. The following description uses the first partition air supply component as an example.

[0074] Reference Figure 23 The first baffle air supply assembly includes a second valve plate 51, a baffle 52, and a screw 53. (Refer to...) Figure 24 and Figure 25 The second valve plate 51 is disposed within the first mounting groove 3061. (Refer to...) Figure 26 and Figure 27 The air supply channel also includes a secondary flow channel 47 and a through hole 48. One end of the through hole 48 connects to the first mounting slot 3061, and the other end connects to the second mounting slot. One end of the secondary flow channel 47 connects to the air inlet 41, and the other end connects to the through hole 48. (Refer to...) Figure 25 The lower second valve plate 51 closes the through hole 48 in the initial state.

[0075] Reference Figure 25 The first mounting groove 3061 has a threaded hole. The screw 53 passes through the baffle 52 and the second valve plate 51 and is connected to the threaded hole so that the baffle 52 and the second valve plate 51 are fixedly installed in the first mounting groove 3061. The refrigerant in the through hole 48 can drive the second valve plate 51 to bend and deform.

[0076] A baffle 52 is disposed outside the second valve plate 51. A second lift limiting part 521 is provided on the side of the baffle 52 facing the second valve plate 51. A gap is provided between the second lift limiting part 521 and the bottom surface of the first mounting groove 3061, allowing the second valve plate 51 to bend and deform within this gap. A second exhaust port 3062 is formed between the baffle 52 and the side wall of the first mounting groove 3061. The second exhaust port 3062 connects to the upper cylinder chamber 3051. (Refer to...) Figure 25 When the air pressure in the upper cylinder chamber 3051 is less than the air pressure in the through hole 48, the pressure difference will cause the second valve plate 51 on the upper side to bend and deform so that the through hole 48 connects to the upper cylinder chamber 3051, and the refrigerant in the through hole 48 can flow into the upper cylinder chamber 3051 to achieve air replenishment.
