Capacity control valve

A capacity control valve comprising:

• a valve housing provided with a discharge port through which a discharge fluid of discharge pressure passes, a suction port through which a suction fluid of suction pressure passes, and a control port through which a control fluid of control pressure passes;
• a rod configured to be driven by a solenoid;
• a CS valve formed by a CS valve seat and a CS valve element and configured to open and close a communication between the control port and the suction port;
• a DC valve formed by a DC valve seat and a DC valve element and arranged movably with respect to the CS valve element, the DC valve being configured to open and close a communication between the discharge port and the control port in accordance with a movement of the rod;
• and
• a pressure drive portion coupled to the CS valve element to be movable in an integrated manner with the CS valve element and arranged in a suction fluid supply chamber which is formed in the valve housing and to which the suction fluid is supplied, the pressure drive portion being driven by the suction pressure, wherein
• the CS valve element and DC valve element are moved together by the movement of the rod while maintaining a closed state of the CS valve, and when the rod is further moved, the CS valve element is moved alone and the DC valve element is left while maintaining a closed state of the DC valve.
