Abstract:
A capacity control valve (1) includes a valve main body (10) having a first communication passage (11), a second communication passage (12), a third communication passage (13), and a main valve seat (15a), a valve element (20) having an intermediate communication passage (29), a main valve portion (21c), and an auxiliary valve portion (23d), and a solenoid (30) having a plunger (35) that drives a first rod (136) and a second rod (36). The first rod (136) opens and closes the main valve portion (21c), and the second rod (36) opens and closes the auxiliary valve portion. The capacity control valve is capable of efficiently discharging a liquid coolant irrespective of pressure of a suction chamber and lowering drive force of a compressor at a liquid coolant discharging operation.
