する回転ピストン型圧縮機。The rotary piston type compressor comprises a rotary piston that is eccentric to the cylinder axis and rolls on the inner surface of the cylinder, and a vane that comes into pressure contact with the rotary piston and separates the cylinder chamber into a suction chamber and a compression chamber. A V-shaped groove is formed in the axial direction on the surface of the rotating piston, and a spring is inserted into the vane chamber in which the vane is housed to press the vane into constant pressure contact with the V-shaped groove. A rotary piston type compressor characterized in that a small chamber formed in the V-shaped groove is connected to a communication hole provided in the rotary piston and constantly communicating with the atmosphere.
