Abstract

A capacity control valve is provided with a throttle valve portion having a communication hole and a second valve hole. The communication hole is provided between a second valve portion and a third valve portion and makes an intermediate communication passage communicate with a third valve chamber. The second valve hole is provided between a second valve chamber and the third valve chamber. An amount of narrowing of the throttle valve portion in relation to a stroke of a valve element is set larger when the second valve portion initially opens by separating from a second valve seat face, and then becomes narrower after the initial opening of the valve. The capacity control valve is capable of shortening a start-up time and improving the operating efficiency of a variable capacity compressor.
