摘要:
A capacity control valve includes: a valve body (10) including first communication passages (11), second communication passages (12), third communication passages (13), and a main valve seat (15a); a valve element (21) including an intermediate communication passage (29), a main valve portion (21b), and an auxiliary valve portion 21c; a solenoid (30) that drives a rod (36) provided with an auxiliary valve seat (23c); a first biasing member (43) that biases in a valve closing direction of the main valve portion (21b); and a second biasing member (44) that biases in a valve closing direction of the auxiliary valve portion (21c), wherein the rod (36) moves relative to the valve element (21) to open and close the auxiliary valve portion (21c). The capacity control valve allows a liquid refrigerant to be efficiently discharged and allows a driving force of a compressor to be decreased.
