CAPACITY CONTROL VALVE

There is provided is a capacity control valve with a favorable control efficiency in normal control. [0002] The capacity control valve includes a valve housing 10, 11 formed with a discharge port 15, a suction port 13, and first and second control ports 14, 16, a rod 51 movably arranged in the valve housing 10, 11 and driven by a solenoid 80, a CS valve 50 configured to control a fluid flow between the first control port 14 and the suction port 13 in accordance with a movement of the rod 51, and a DC valve 53 configured to control a fluid flow between the second control port 16 and the discharge port 15 in accordance with the movement of the rod 51. In a non-energization state of the solenoid 80, the CS valve 50 is closed and the DC valve 53 is closed. As the energization of the solenoid 80 becomes larger, the CS valve 50 transitions from a closed state to an open state and the DC valve 53 transitions from a closed state to an open state. In a maximum current state of the solenoid 80, the CS valve 50 is opened and the DC valve 53 is opened.
