When high-pressure oil is fed into the cavity A and the cavity G, the cavity B and the cavity F are subjected to low-pressure oil return, the first piston rod assembly 350 moves towards the cavity D along the cavity A, the volume of the cavity D is reduced, the gas pressure in the cavity D is increased, gas in the gas inlet pipeline 200 cannot enter the cavity D, when the gas pressure in the cavity D is increased to the opening pressure set by the second one-way valve 401, part of gas in the cavity D enters the gas outlet pipeline 400 of the compressor, at the moment, the gas pressure in the cavity D still keeps the existing motion state, the gas pressure in the cavity D is further increased, when the gas pressure in the cavity D is increased to the set value of the pressure sensor 303, the reversing motion of the first piston rod assembly 350 and the second piston rod assembly 360 occurs through the PLC control system, the gas pressure in the cavity D is reduced, when the gas pressure in the cavity D is smaller than the opening pressure set by the second one-way valve 401, the gas in the cavity D cannot flow into the gas outlet pipeline 400, when the gas pressure in the cavity D is smaller than the gas pressure in the gas inlet pipeline 200, the gas in the cavity D enters the gas inlet pipeline 200, the compressor still enters the first piston rod assembly 350 again, the reversing motion state is still kept by the two preset piston rod assemblies, and the piston rod assemblies move to the first piston rod assembly 360 and the second piston rod assembly moves again, and the piston rod assembly moves to the second piston rod assembly 360 through the preset position.
