Patent attributes
A capacity control valve for controlling a capacity of a fluid includes: a valve housing; a main valve closing and opening a communication between a Pc port and a Pd port when a main valve portion of a main valve element driven by a drive force of a solenoid comes into contact with and separates from a main valve seat; a pressure-sensitive valve which is opened by an ambient pressure; a hollow tube member which forms a part of the pressure-sensitive valve and allows the Pc port to communicate with a Ps port through a hollow communication path formed therein when the pressure-sensitive valve is opened; and an auxiliary communication path allows the Pc port to communicate with the Ps port independently of the pressure-sensitive valve, and the auxiliary communication path is configured to be able to increase a flow path cross-sectional area after the main valve is closed.
