Claims

[Scope of utility model registration request]

an electric motor section housed in a sealed container, a compression mechanism section driven by the electric motor section, and a capacity control valve that appropriately opens and closes a release hole communicating with an intermediate compression section in a cylinder forming the compression mechanism section. The capacity control valve includes a back pressure pipe that applies back pressure to the capacity control valve, and a bypass pipe that communicates the release hole and the suction hole, and the capacity control valve has a flat plate-shaped opening/closing valve that abuts a valve seat provided in the release hole. A rotary compressor comprising a leg piece formed on the outer periphery of the opening/closing part and bent into a U-shape that is close to the inner wall of the release hole and abuts on the stopper.
