Abstract:
A capacity control valve includes a valve housing formed with a discharge port, a suction port, and first and second control ports, a rod movably arranged in the valve housing and driven by a 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 the movement of the rod. In a non-energization state, the CS valve is closed and the DC valve is closed. As the energization of the solenoid becomes larger, the CS valve transitions from a closed state to an open state and the DC valve transitions from a closed state to an open state.
