ことを特徴とする可変容量ベーン型回転圧縮機。 A movable plate that bypasses a portion of the compressed gas of the compressor to the suction side to change the flow rate of the compressed gas discharged, and an actuator that drives the movable plate according to control pressure, the actuator being connected to the cylinder. and the inside of the cylinder is divided into a first cylinder chamber and a second cylinder chamber.
A piston is defined in the first cylinder chamber and moves in response to a differential pressure between the control pressures supplied to each cylinder chamber to drive a connected movable plate; a biasing member that biases and presses toward the second cylinder chamber side, and variable capacity vane type rotary compression that controls the control pressure supplied to the second cylinder chamber of the actuator to change the discharge amount of the compressor. In the compressor, when the piston of the actuator is pressed by the biasing member and moves to the end of the cylinder on the second cylinder chamber side, the piston and the movable plate are connected so that the movable plate minimizes the discharge amount of the compressor. However, when the compressor stops and the control pressure no longer acts on the actuator, the piston is stopped at the end on the second cylinder chamber side, and the compressor is started from the minimum displacement state. Features a variable capacity vane type rotary compressor.
