ア・コンプレツサの配管回路。[Claims for Utility Model Registration] A piston fitted into a cylinder so as to be able to slide in the axial direction and a displacement chamber formed by the cylinder are connected to a suction hole through a suction valve on one side, and are connected to a suction hole on the other side through a suction valve. In a piping system that is connected to a discharge hole via a discharge valve, and the air pressure signal of an air tank connected to the discharge hole is the opening signal of an unloader valve that selectively opens the suction valve, The communicating suction pipe is configured such that when the air pressure is below a predetermined air pressure corresponding to operating the unloader valve, the suction hole is communicated with the suction pipe communicating with the atmosphere, and the air pressure becomes equal to or higher than the predetermined air pressure. A piping circuit for an air compressor in which a switching valve is interposed so that the suction hole communicates with the hydraulic oil storage section and the suction pipe and the suction hole are disconnected from each other during the operation.
