the connecting rod (10) is driven to move through the rotation of the disc (9), so that the piston rod (113) moves up and down in a reciprocating manner;

the piston rod (113) presses down the pressure plate (1171) to enable the gas in the lower pressure plate (1171) to flow into the piston port (112), and the lower pressure rod (1174) moves downwards through the air pressure above the lower pressure plate (1171);

the lubricating oil in the compressed lubricating oil storage tank (118) flows into the lubricating oil tank (14) from the oil delivery pipe (13).
