摘要:
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), a solenoid (30) that drives a rod (36) having an auxiliary valve seat (26c), and a first biasing member (43) that biases in the valve closing direction of the main valve portion (21c). The rod (36) is relatively moved with respect to the valve element (20) so as to open and close the auxiliary valve portion. The capacity control valve can efficiently discharge a liquid coolant irrespective of pressure of a suction chamber and lower drive force of a compressor at a liquid coolant discharging operation.
