Abstract
A control valve for a variable displacement compressor, in which the discharge pressure of the compressor introduced into a pressure sensing section applies urging force to a movement member, and a solenoid section applies, in cooperation with the urging force, urging force to the movement member depending on an input signal. The degree of opening of a valve body provided at the movement member is set according to the position of the movement member to regulate the rate of air flow in a communication path for interconnecting a discharge pressure region of the compressor and a compressor inner chamber. The suction pressure of the compressor is introduced into a control valve to apply urging force to the movement member, and communication between fluid having the discharge pressure introduced into the pressure sensing section and fluid having the suction pressure introduced into the control valve is shut off.
