Control valve
Abstract:
The present invention relates to a control valve capable of performing capacity control independent of the pressure of operation fluid. In the control valve which opens and closes a first poppet valve and a second poppet valve by a solenoid section the following pressure-receiving areas relating to the first poppet valve and the second poppet valve are set to be substantially equal to each other: the first effective pressure-receiving area of a first pressure-sensing spring device, the second effective pressure-receiving area of a second pressure-sensing spring device, the first pressure-receiving area on the inner side of a portion where a first valve seat surface and a first valve section surface are in contact with each other, and the second pressure-receiving area on the inner side of a portion where a second valve seat surface and a second valve section surface are in contact with each other.
