摘要:
A capacity control valve includes a valve housing provided with a main valve seat; a main valve body that is inserted into the valve housing and includes a main valve portion which is capable of seating on the main valve seat 10a to open and close a communication between a suction port and a control port using a driving force of a solenoid; and a pressure-sensitive body that applies a biasing force to the main valve body in an opening direction according to pressure of a fluid surrounding the pressure-sensitive body. The fluid is supplied from the control port to around the pressure-sensitive body, and the fluid is supplied from the suction port to a back pressure side of the main valve body.
