Control valve, and control valve for variable displacement compressor using the control valve

摘要

A control valve includes a diaphragm assembly imparting a biasing force to a moving member according to the pressure introduced into the pressure-sensitive part. The moving member is moved by the biasing force to control the valve opening. The control valve further includes a solenoid part which imparts the thrust of the diaphragm assembly produced according to the pressure introduced into the pressure-sensitive part to the moving member through a diaphragm holding body as a biasing force, and imparts a biasing force capable of controlling the valve opening in cooperation with the afore-said biasing force to the moving member.
