Capacity control valve

A capacity control valve comprising:

• a valve housing provided with a discharge port allowing a discharge fluid of a discharge pressure to pass therethrough, a suction port allowing a suction fluid of a suction pressure to pass therethrough, and a control port allowing a control fluid of a control pressure to pass therethrough;
• a primary valve including a primary valve seat and a primary valve body driven by a solenoid and opening and closing a communication between the discharge port and the control port by a movement of the primary valve body;
• and
• a control-suction valve which includes a control-suction valve body, a first spring configured to urge the control-suction valve body in a closing direction of the control-suction valve, and a second spring configured to urge the control-suction valve body in an opening direction of the control-suction valve,
• the control port and the suction port being opened at a valve closed position of the primary valve body,
• the control port and the suction port being closed at a valve opened position of the primary valve body,
• wherein the capacity control valve further comprises a pressure drive valve which is opened and closed in accordance with the suction pressure, and
• the primary valve body constitutes a part of a hollow rod provided with a hollow communication path capable of causing the control port to communicate with the suction port by opening and closing the pressure drive valve.
