DETAILED DESCRIPTION

[0014] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0015] Any feature disclosed in this specification (including any appended claims, abstract, and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0016] according to Figure 1-Figure 5 As shown, an adjustable vane compressor includes a cylinder 1, and end covers 2 are provided at the front and rear ends of the cylinder 1. The end covers 2 are sealed and connected to the cylinder 1. The cylinder 1 is the main structural part of the compressor, and its front and rear ends are sealed and connected through the end covers 2 to form a closed compression cavity; an eccentrically arranged rotor 3 is provided in the cylinder 1, and a plurality of evenly distributed vanes 31 are also provided on the rotor 3. The ends of the vanes 31 are designed to be arc-shaped so that the ends of the vanes 31 can better fit the inner wall of the cylinder 1. The vanes 31 divide the cavity in the cylinder 1 into a plurality of intake chambers 4 and compression chambers 5. The rotor 3 rotates axially clockwise in the cylinder 1, and the centrifugal force generated by its rotation acts on the vanes 31, so that the vanes are thrown out and fit closely to the inner wall of the cylinder, thereby forming a sealed intake chamber 4 and compression chamber 5 in the cylinder. Since the rotor 3 is eccentrically arranged In the cylinder, as the rotor 3 continues to rotate clockwise, the gas in the compression chamber 5 will be gradually compressed; a mounting shaft and a transmission shaft 32 are respectively provided at both ends of the rotor 3; an oblong groove 21 is also provided on the end cover 2, and a movable shaft sleeve 22 is provided in the oblong groove 21. The mounting shaft and the transmission shaft 32 are arranged in the shaft sleeves 22 at both ends, so that the rotor 3 is arranged in the cylinder 1 through the shaft sleeve 22. An adjusting screw 6 is also provided on the shaft sleeve 22, and the adjusting screw 6 is arranged in the end cover 2. One end of the adjusting screw 6 is connected to the shaft sleeve 22, and the other end passes through the end cover 2 and is provided with a rotating handle 61. By rotating the handle 61, the position of the shaft sleeve 22 can be adjusted. Since the two ends of the rotor 3 are respectively connected to the two shaft sleeves 22, adjusting the position of the shaft sleeve 22 can change the eccentricity of the rotor 3, thereby realizing the control of the pressure of the compressed gas.

[0017] An air inlet 23, an oil inlet hole 24 and an exhaust port 25 are provided on the one side end cover 2. The air inlet 23 and the oil inlet hole 24 are connected to the air inlet chamber 4. External gas can enter the cylinder 1 through the air inlet 23, thereby realizing the gas compression process. The oil hole 24 is used to introduce lubricating oil to reduce the wear of internal components of the compressor and help maintain air tightness. The exhaust port 25 is connected to the compression chamber 5. The exhaust port 25 can allow the compressed gas to be discharged from the cylinder 1, thereby completing the compression cycle.

[0018] The rotor 3 is provided with a plurality of slide grooves 33 adapted to the slide vanes 31, and the slide vanes 31 are arranged in the slide grooves 33. A compression spring 34 is also provided between the slide grooves 33 and the slide vanes 31. A cavity 35 is formed between the slide grooves 33 and the slide vanes 31 to maintain a relative seal with the intake chamber 4 and the compression chamber 5. The compression spring 34 ensures that the slide vanes 31 can maintain close contact with the inner wall of the cylinder 1, thereby improving the sealing performance and compression efficiency.

[0019] An air inlet groove 26 and an exhaust hole 27 are respectively provided at both ends of the oblong groove 21. The air inlet groove 26 is provided at an end close to the air inlet chamber 4, and the exhaust hole 27 is provided at an end close to the compression chamber 5. By providing the air inlet groove 26 and the exhaust hole 27, air can pass through the air inlet groove 26 into the cavity 35 at one end close to the compression chamber 5. Then, during the rotation of the rotor 3, the gas in the cavity 35 will be compressed and then discharged from the exhaust hole 27, just like in the compression chamber 5. This can effectively utilize the space in the cylinder 1 and improve the compression efficiency.

[0020] A transmission rod 62 is provided above the adjusting screws 6 on both sides, and a driving gear 63 is provided on the adjusting screw 6. A driven gear 64 meshing with the driving gear 63 is provided on the transmission rod 62. The driving gear 63 and the driven gear 64 are configured as helical bevel gears. When the rotating handle 61 is rotated through the configuration of the transmission rod 62, the driving gear 63 cooperates with the driven gear 64. Through the transmission rod 62, it is ensured that when adjusting the rotor 3, the adjusting screws 6 on both sides can move synchronously, maintain the balance and stability of the rotor, and prevent the rotor 3 from tilting.

[0021] The exhaust port 25 is connected to the oil-gas separator 7, and the lubricating oil and gas in the compressed gas can be separated through the oil-gas separator connection 7 to ensure the cleanliness of the gas. The oil-gas separator is arranged outside the cylinder 2, and the bottom of the oil-gas separator is connected to the cylinder 1 through an oil pipe. The bottom of the oil-gas separator 7 is connected to the cylinder 1 through an oil pipe, forming an oil recovery system, which can recover the separated lubricating oil and return it to the cylinder 1, realizing the recycling of the lubricating oil and reducing the consumption and waste of the lubricating oil.

[0022] In practice, at the beginning of compression, the position of the rotor 3 can be adjusted by turning the rotating handle 61, the eccentric position can be adjusted, and the output gas pressure can be adjusted; at the beginning of the rotation of the rotor 3, the slider 4 will move toward the inner wall of the cylinder 1, so that the space of the intake chamber 4 and the cavity 35 will gradually expand, and then air will be inhaled through the air inlet 23 and the air inlet groove 26; during the rotation process, the volume of the space in the intake chamber 4 and the cavity 35 will also become larger and larger until it reaches the maximum volume; then continue to rotate, the volume of the space in the intake chamber 4 and the cavity 35 begins to shrink, at this time the intake chamber 4 becomes the compression chamber 5, and begins to compress the gas until the gas is discharged from the exhaust port 25 and the exhaust hole 27, and then continue to rotate, the volume of the space in the compression chamber 5 and the cavity 35 begins to increase, and the compression chamber 5 becomes the new intake chamber 4, and the cycle is repeated to compress the air.

[0023] This design is ingenious. By adjusting the settings of the screw 6 and the sleeve 22, the position of the rotor 3 can be precisely adjusted, thereby flexibly controlling the pressure of the compressed gas, thereby improving the adaptability and flexibility of the compressor. In addition, through the settings of the air inlet groove 26 and the exhaust hole 27, combined with the cavity 35 between the slide groove 33 and the slide vane 31, the spatial change of the cavity 35 can be effectively utilized to bring additional compressed gas output, thereby improving the working efficiency of gas compression.

[0024] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
