摘要:
A capacity control valve includes a valve housing; a main valve including a valve body driven by a solenoid, and a main valve seat between a discharge port and a control port and with which the valve body is contactable; and a pressure sensitive valve member disposed in a pressure sensitive chamber and forming a pressure sensitive valve, together with a pressure sensitive body. The control port and a suction port communicate with each other through an intermediate communication passage by opening the pressure sensitive valve. The pressure sensitive valve member has a through-hole communicating with the intermediate communication passage and has a slide valve body attached thereto such that the slide valve body slides relative to the pressure sensitive valve member to open and close the through-hole. A biasing device is provided on a radially outer side of the slide valve body.
