Abstract
The present invention discloses a bleed valve for use in gas turbine engines. The valve has a piston, one end of which is positioned inside a housing which is positioned on one side of the by pass fluid flow path. The other end of the piston is positioned in an opening between the primary fluid flow path and the bypass fluid path such that the valve opens and closes in response to a pressure differential between two points in the primary fluid flow path.
