Capacity control valve

A capacity control valve comprising:

• a valve housing provided with a discharge port through which a discharge fluid of a discharge pressure passes, a suction port through which a suction fluid of a suction pressure passes, and a control port through which a control fluid of a control pressure passes;
• a main valve including a valve body driven by a solenoid, and a main valve seat which is provided between the discharge port and the control port and with which the valve body is allowed to come into contact;
• a pressure sensitive body disposed in a pressure sensitive chamber;
• and
• a pressure sensitive valve member extending from the valve body to the pressure sensitive chamber and forming a pressure sensitive valve, together with the pressure sensitive body,
• wherein an intermediate communication passage is formed in the valve body and in the pressure sensitive valve member, and the control port and the suction port are allowed to communicate with each other through the intermediate communication passage by opening the pressure sensitive valve,
• the pressure sensitive valve member is provided with a through-hole communicating with the intermediate communication passage, and has an opening and closing member attached thereto such that the opening and closing member is restricted in movement with respect to the valve housing by a restriction device and slides relative to the pressure sensitive valve member to open and close the through-hole,
• the restriction device includes an elastic body restricting movement of the opening and closing member, and
• the elastic body presses the opening and closing member toward a flange portion formed in the pressure sensitive valve member on a side of the pressure sensitive body with respect to the through-hole of the pressure sensitive valve member.
