Abstract
Provided is A displacement control valve which includes a valve housing, a valve element constituting a main valve that contacts and separates from a main valve seat, for opening and closing communication between discharge ports and control ports by driving force of a solenoid, a pressure-sensitive valve that opens and closes according to ambient pressure, and a pressure-sensitive valve member constituting the pressure-sensitive valve together with a pressure-sensitive element. The valve element and the pressure-sensitive valve member are formed with an intermediate communicating passage which allows communication between the control ports and the suction ports by opening and closing of the pressure-sensitive valve.
