Abstract
A valve capable of smoothly changing pressure is provided. The valve includes a housing that partitions a first space into which a suction fluid flows, a second space into which a discharge fluid flows, and a third space into which a control fluid flows, and a valve element to be separated from and seated on the housing so that fluid flows in and out the third space, and a pressure receiving surface of the discharge fluid acting on the valve element is narrower than a pressure receiving surface of the suction fluid acting on the valve element.

A pressure control valve, comprising:
- a housing configured to partition a first space into which a suction fluid flows, a second space into which a discharge fluid flows, and a third space into which a control fluid flows;
- and
- a valve element configured to be separated from and seated on the housing so that fluid flows in and out the third space,
- wherein a pressure receiving surface of the discharge fluid acting on the valve element is narrower than a pressure receiving surface of the suction fluid acting on the valve element, and
- pressure of the discharge fluid and pressure of the control fluid act on the valve element in opposed directions upon separation and seating of the valve element.
