Capacity control valve and capacity control valve control method

A 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). The capacity control valve can efficiently discharge a liquid refrigerant and can decrease a driving force of a compressor during a liquid refrigerant discharge operation.
