Claim 8:
9. A capacity control valve for controlling a flow rate by energization of a solenoid, comprising:
a valve housing formed with a discharge port through which discharge fluid with a discharge pressure passes, a suction port through which suction fluid with a suction pressure passes, and first and second control ports through which control fluid with a control pressure passes;
a rod arranged in the valve housing and driven by the solenoid;
a CS valve configured to control a fluid flow between the first control port and the suction port in accordance with a movement of the rod; and
a DC valve configured to control a fluid flow between the second control port and the discharge port in accordance with a movement of the rod,
wherein in a non-energization state of the solenoid, the CS valve is closed and the DC valve is opened,
wherein in a maximum current state of the solenoid, the CS valve is opened and the DC valve is closed, and
wherein in energization control of the solenoid, the CS valve transitions from a closed state to an open state and the DC valve transitions from an open state to a closed state, and the DC valve is closed with a stroke of equal to or longer than a predetermined stroke shorter than a maximum stroke of the rod,, wherein the DC valve includes a DC valve body slidably attached to the rod and a DC valve seat formed in the valve housing, and, wherein a flange portion extending in a radially outward direction and configured to restrict movement of the DC valve body in a closing direction of the DC valve is provided in the rod.
