量コンプレツサ。 A piston that rotates and 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. The adjustment device supplies the suction pressure of the bellows chamber housing the bellows and the discharge pressure of the discharge pressure path provided with the one-way valve as pilot pressure through a straight path into which the poppet valve is loosely fitted;
A variable displacement compressor characterized in that the poppet valve and the bellows are urged by elastic force so that they are always in contact with each other.
