摘要:
A displacement control valve includes an electromagnetic solenoid, a drive force transmitting body actuated, and a pressure sensitive portion having a pressure sensitive body that selectively extends and contracts in the movement direction of the drive force transmitting body in correspondence with pressure in a pressure sensitive chamber. A first valve body is arranged in the pressure sensitive body to adjust the cross-sectional area of an outlet passage. A second valve body is connected to the drive force transmitting body to adjust the cross-sectional area of a supply passage. The pressure sensitive body is movable in the movement direction of the drive force transmitting body in the pressure sensitive chamber. The pressure sensitive chamber is configured to communicate with the control pressure chamber. The pressure sensitive body is urged by the pressure in the control pressure chamber in the direction in which the first valve body closes.
