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