Abstract:
A capacity control valve includes a valve housing. A main valve including a valve body is driven by a solenoid, and a main valve seat which is provided between a discharge port and a control port and with which the valve body 51 is allowed to contact. A pressure sensitive valve member forming a pressure sensitive valve with a pressure sensitive body is disposed in a pressure sensitive chamber. The control port and a suction port communicate through an intermediate communication passage by opening the pressure sensitive valve. A slide valve body slides relative to the pressure sensitive valve member to open and close a through-hole communicating with the intermediate communication passage. The slide valve body partitions the pressure sensitive chamber into a Pd side space and a Pc side space, and a Pd-Pc flow passage providing communication between two spaces and is formed in the slide valve body.
