Claim 14:
15. 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 the DC valve body is arranged between an outer periphery of the rod and an inner periphery of the valve housing so as to partition the suction port and the discharge port.
