特徴とする可変容量ベーン型回転圧縮機。 A cylindrical cam ring, a pair of side plates that seal both open ends of the cam ring, a casing that houses the cam ring and the pair of side plates, a cylinder that is built into the casing, and that is slidably inserted into the cylinder. an actuator which has a piston defining a pressure action chamber in the cylinder, and in which the piston is actuated by introducing control pressure into the pressure action chamber, the control member being connected to the piston of the actuator and compressed by the operation of the piston. In a variable capacity vane type rotary compressor that variably controls the discharge capacity of the machine, the cam ring;
A void chamber is defined between a pair of side plates and a casing, and a pressure acting chamber of the actuator is communicated with the void chamber to increase the volume of the pressure acting chamber without changing the external shape of the compressor. Variable capacity vane type rotary compressor.
