An expansion valve having a high valve opening adjustment accuracy includes: a valve housing which is provided with an inlet port allowing a refrigerant from a condenser to pass therethrough and an outlet port allowing a refrigerant toward an evaporator to pass therethrough; a valve body which is driven by a solenoid; a valve seat on which the valve body sits; and an urging member configured to urge the valve body in a valve closing direction, a space is formed on a valve opening direction side of the valve body, and the refrigerant on the valve closing direction side in relation to the valve body flows into the space.

Expansion valve

A valve includes: a housing having a primary pressure space and a secondary pressure space; a valve seat disposed between the primary pressure space and the secondary pressure space; a valve body that is driven in an axial direction by a driving source to be seated on or separate from the valve seat; and a communication passage that provides communication between a back space adjacent to one of the primary pressure space and the secondary pressure space and remaining one of the primary pressure space and the secondary pressure space. A partition member is disposed between the valve housing and the valve body, and the back space and the one of the primary pressure space and the secondary pressure space are partioned off from each other in a sealed state by the partition member.

Valve

A capacity control valve includes a valve housing; a main valve including a valve body driven by a solenoid, and a main valve seat between a discharge port and a control port and with which the valve body is contactable; and a pressure sensitive valve member disposed in a pressure sensitive chamber and forming a pressure sensitive valve, together with a pressure sensitive body. The control port and a suction port communicate with each other through an intermediate communication passage by opening the pressure sensitive valve. The pressure sensitive valve member has a through-hole communicating with the intermediate communication passage and has a slide valve body attached thereto such that the slide valve body slides relative to the pressure sensitive valve member to open and close the through-hole. A biasing device is provided on a radially outer side of the slide valve body.
