の制御弁。[Claims for Utility Model Registration] (1) A rocking plate installed in the crank chamber with a variable angle of inclination, which is connected to the rocking plate and moves back and forth to compress the refrigerant from the suction chamber and discharge it into the discharge chamber. In a variable displacement compressor, the displacement variable compressor has a piston, and the displacement amount of the piston is changed by changing the inclination angle of the rocking plate depending on the difference between the pressure in the crank chamber and the pressure in the suction chamber. , an actuating rod that opens and closes in conjunction with a first valve part that opens and closes communication between the suction chamber and the crank chamber, and a second valve part that opens and closes communication between the discharge chamber and the crank chamber, and the suction chamber. A variable displacement compressor, comprising: a diaphragm attached to the operating rod so as to receive pressure; and urging means for urging the operating rod in a direction against the pressure. control valve. (2) The control valve for a variable displacement compressor according to claim 1, wherein the biasing force of the biasing means is variable.
