とする可変容量コンプレツサ。 A piston that rotationally adjusts an adjustment plate to change the compression start position of a vane that rotates integrally with the rotor, and a pressure adjustment device that applies pilot pressure to the piston, and a pair of pistons that are adjacent to each other from a bypass opening of the adjustment plate. A variable displacement compressor that pressurizes and discharges the fluid that has flowed into the working chamber between the vanes of the piston. A regulating device selectively regulates and supplies the pump suction pressure and discharge pressure as pilot pressure, and the top wall of the piston is provided with a valve body that opens when the difference between the pilot pressure and the pump suction pressure falls below a predetermined value. A variable capacity compressor characterized by:
