Abstract
A capacity control valve includes a valve housing provided with a discharge port, suction ports, a control port and a primary valve driven by a solenoid. The capacity control valve further includes a differential CS valve which includes a differential CS valve body disposed so as to be relatively movable in an axial direction with respect to the primary valve bodies. The differential CS valve body divides a control pressure chamber into a discharge side control chamber communicating with the first control port and a suction side control chamber communicating with the second control port in the axial direction and operates the differential CS valve body by a differential pressure between the discharge side control chamber and the suction side control chamber so as to open the second control port and the suction port.
