[0027] The shell 2 is provided with a fixed plate 57 corresponding to the mounting sleeve 52 on one side, a long hole 58 is opened on the fixed plate 57, the long hole 58 allows the insertion rod 54 and the knob 55 to pass, the fixed plate 57 on both sides of the long hole 58 is provided with a limiting slot 59 corresponding to the limiting block 56, the staff can pull up the knob 55 by hand, the knob 55 drives the insertion rod 54 and the disc 53 to rise, the disc 53 extrudes the return spring 510, then the knob 55 is rotated 90 degrees with the insertion rod 54 as the center, the limiting block 56 at the bottom of the knob 55 is aligned with the limiting slot 59 and clamped in, when the external force disappears, the return spring 510 releases the elastic potential energy, provides the downward force for the knob 55 and the limiting block 56, so that the limiting block 56 is firmly clamped in the limiting slot 59, realizes the stable and convenient installation between the rotor seat body 1 and the shell 2, and ensures the stability when the gas compressor works.

[0028] In use, first, the staff aligns the shell 2 with the rotor seat body and installs, the long hole 58 on the several fixed plates 57 on the outer side of the shell 2 passes through the knob 55 and the insertion rod 54, the fixed plate 57 is placed on the top surface of the mounting sleeve 52, then the knob 55 is pulled up by hand, the knob 55 drives the insertion rod 54 and the disc 53 to rise, the disc 53 extrudes the return spring 510, then the knob 55 is rotated 90 degrees with the insertion rod 54 as the center, the limiting block 56 at the bottom of the knob 55 is aligned with the limiting slot 59 and clamped in, when the external force disappears, the return spring 510 releases the elastic potential energy, provides the downward force for the knob 55 and the limiting block 56, so that the limiting block 56 is firmly clamped in the limiting slot 59, realizes the stable and convenient installation between the rotor seat body 1 and the shell 2, and ensures the stability when the gas compressor works.

[0029] When the gas compressor is started, the gas enters the compressor through the gas inlet 36, the camshaft rotor disc 32 rotates in the rotor seat body 1, and the entering gas is compressed by the compression ring 31. With the rotation of the camshaft rotor disc 32, the compression ring 31 gradually reduces the volume of the gas and increases the pressure of the gas, and the high-pressure gas is output from the gas outlet 37. When the camshaft rotor disc 32 rotates, the compression ring 31 is subjected to pressure, and the compression rod 34 slides in the open slot 35 and reciprocates, pushing the mounting block one 38 and compressing the spring one 313. The spring one 313 buffers the impact force on the compression rod 34 through the elastic force of the spring one 313, and the piston rod 39 and the piston one 310 move in the oil storage cylinder 312. The piston one 310 divides the space in the oil storage cylinder 312 into two chambers, and the hydraulic oil in the oil storage cylinder 312 repeatedly flows from one chamber to the other chamber through different small holes on the piston. In the process of hydraulic oil flow, the friction between the hole wall and the hydraulic oil and the internal friction between the hydraulic oil molecules hinder the flow of the hydraulic oil, thereby generating a damping force, reducing the speed of the spring one 313 rebounding, avoiding the rapid spring of the spring one 313 aggravating vibration, effectively buffering the vibration generated by the camshaft rotor disc 32, and improving the stability and service life of the gas compressor.

[0030] During the use of the gas compressor, the rotor seat body 1 can be periodically removed, the sealing cover 42 can be unscrewed and removed, and lubricating oil can be added to the oil inlet 41. The lubricating oil enters the two side restraint grooves 43 through the oil inlet 41 and the oil groove. When the extrusion block 47 is not extruded, the extrusion block 47 cooperates with the sealing ring 49 on the restraint groove 43 to prevent leakage of the lubricating oil. When the gas compressor is working, the compression ring 31 extrudes the extrusion block 47, and the flexible spring 48 is compressed. Because the front part of the extrusion block 47 is smaller than the rear part, a gap is formed between the extrusion block 47, the sealing ring 49 and the restraint groove 43. The lubricating oil in the oil groove and the restraint groove 43 is extruded by the pressure when the extrusion block 47 retracts, and flows out through the gap to lubricate the inside of the rotor seat body 1. The combination of the moving guide pillar 46 and the guide pillar guide sleeve 45 can ensure the stability of the extrusion block 47 when it retracts into the restraint groove 43, prevent the extrusion block 47 from deviating and causing the lubricating oil to leak when it returns to its original position, and solve the problem of damage to the rotor seat body 1 and the compression ring 31 caused by long-term use. The rotating compression ring 31 can be lubricated by extruding the extrusion block 47 inside the rotor seat body 1, reducing maintenance costs.
