Abstract
A bleed valve includes inlet and outlet housings, a hollow shaft defining a valve axis, and a full-area piston. The shaft includes a first end mounted to an inner diameter portion of the inlet housing and a second end mounted to an end cap of the outlet housing. The piston is slidably mounted to the shaft. A first chamber is defined between an upstream side of the piston and the inner diameter portion of the inlet housing. A second chamber is defined between a downstream side of the piston and the end cap of the outlet housing. An area of an upstream surface of the piston at an angle with respect to the valve axis is in fluid communication with the first chamber, and is substantially equal to an area of a downstream surface of the piston at an angle with respect to the valve axis and in fluid communication with the second chamber.
