CAPACITY CONTROL VALVE AND CAPACITY CONTROL VALVE CONTROL METHOD

[Technical problem] To provide a capacity control valve that allows a liquid refrigerant to be efficiently discharged regardless of a pressure in a suction chamber and allow a driving force of a compressor to be decreased during a liquid refrigerant discharge operation[Solution Problem] The capacity control valve includes: a valve body 10 having first communication passages 11, second communication passages 12, third communication passages 13, and a main valve seat 15a; a valve element 20 having an intermediate communication passage 29, a main valve portion 21c and an auxiliary valve portion 23d; a pressure-sensitive element 24 disposed in the valve body 10; a solenoid 30 that drives a rod 36; a first biasing member 43 that biases in a valve closing direction of the main valve portion 21c; and a second biasing member 44 that biases in a valve opening direction of the main valve portion 21c, wherein the rod 36 moves relative to the valve element 20 to press the pressure-sensitive element 24.
