Abstract
A capacity control valve () includes a valve main body () having a first communication passage (), a second communication passage (), a third communication passage (), and a main valve seat (), a valve element () having an intermediate communication passage (), a main valve portion (), and an auxiliary valve portion (), a solenoid () that drives a rod () having an auxiliary valve seat (), and a first biasing member () that biases in the valve closing direction of the main valve portion (). A spring constant of the first biasing member () has a characteristic that the spring constant is increased in an opened state of the main valve portion () and decreased in a closed state. The capacity control valve can efficiently discharge a liquid coolant and lower drive force of a compressor at a liquid coolant discharging operation.
