Abstract:
A capacity control valve includes: a housing with a Pc port, a Pd port, a first Ps port and a second Ps port; a main valve element having a main valve portion adapted to contact with and separate from a main valve seat to close and open a communication between the Pd port and the Pc port by a drive force of a solenoid; an intermediate communication path communicating with the Pc port and the first Ps port; a pressure-sensitive valve configured to open and close the intermediate communication path by an ambient pressure; and a differential pressure valve including a differential pressure valve element configured to open and close a communication between the Pc port and the second Ps port and a communication between the Pc port and a pressure-sensitive chamber by the differential pressure valve element moved by a pressure.
