[Problem] To provide a variable capacity compressor which is capable of inhibiting leakage of a refrigerant that flows out directly to an intake chamber without passing through a crank chamber during operation at minimum discharge capacity, is capable of inhibiting increases in the minimum discharge capacity as a result of increases in the refrigerant pressure in the crank chamber, and is capable of inhibiting lubrication deficiency of sliding parts or the like in the crank chamber. [Solution] A pressure release passage (320) is formed in a first control valve which controls the opening amount of a pressure supply passage connecting a discharge chamber and a crank chamber. The pressure release passage (320) sequentially passes through a first pressure-sensitive chamber (302), a communication hole (306a) of a coupling part (306), a communication hole (304a) connecting the coupling part (306) and the inside of a valve body (304), a helical groove (309a) formed in a solenoid rod (309) section press-fitted into the valve body, and a second pressure-sensitive chamber (307), communicates with an intake chamber (141), and releases, into the intake chamber (141), refrigerant in a pressure-supply-passage area located downstream with respect to the first control valve. An opening/closing means, which closes the pressure release passage (320) when the first control valve is open, is formed from the valve body (304) and a fixed core (310), which come into contact with each other when the first control valve is in a fully open state. |
