Abstract

A capacity control valve includes: a valve body () having first communication passages (), second communication passages (), third communication passages (), and a main valve seat (); a valve element () having an intermediate communication passage (), a main valve portion () and an auxiliary valve portion (); a pressure-sensitive element () disposed in the valve body (); a solenoid () that drives a rod (); a first biasing member () that biases in a valve closing direction of the main valve portion (); and a second biasing member () that biases in a valve opening direction of the main valve portion (), wherein the rod () moves relative to the valve element () to press the pressure-sensitive element (). 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.
