发明名称 Electromagnetic displacement control valve in clutchless type variable displacement compressor
摘要 An electromagnetic displacement control valve in a clutchless type variable displacement compressor is disclosed. The control valve includes a valve body, an electromagnetic driving device, a buffer spring, and an urging spring. The electromagnetic driving device drives the valve body toward a position for closing the valve hole. The buffer spring urges the valve body toward the position for closing the valve hole. The urging spring urges the valve body in a direction away from the position for closing the valve hole against an elastic urging force of the buffer spring. In a state where no current is supplied to the electromagnetic driving device, the valve body is capable of moving in a direction away from the position for closing the valve hole against the elastic urging force of the buffer spring.
