Capacity control valve and capacity control valve control method
摘要:
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.
