Abstract: A bleed valve includes a housing with an inlet coupled to an outlet by a duct, a guide tube with an orifice fixed in the housing between the inlet and the outlet, a piston, and baffle. The piston is slideably supported on the guide tube and is movable between an open and a closed position, the duct fluidly coupling the inlet and outlet in the open position, the duct fluidly separating the inlet and outlet in the closed position. The orifice fluidly couples the inlet and outlet in the open and closed positions to move piston between the open and closed positions according to differential pressure between the bleed valve inlet and outlet. The baffle is slideably supported by the guide tube to set the differential pressure at which the piston moves between the open and closed positions. Gas turbines and differential pressure adjustment methods are also described.

Abstract: Disclosed is a method of applying a biasing force against a piston in a valve as the piston moves along a piston stroke axis in a first direction and an opposing second direction, the piston having a first axial end that is a distal end of the piston, the method including: moving the piston along a piston stroke axis in the first direction and the opposing second direction, wherein while moving the piston along the piston stroke axis: applying a first biasing force in the second direction against the first axial end of the piston from a first spring, and applying a second biasing force in the second direction against the first spring from a second spring.

Abstract: A pressure relief valve controller (PRVC) includes a housing having a spring, a spring seat connected to the spring, a piston, and a portion of which is disposed between the spring seat and the piston, wherein one or more grooves and/or protrusions are disposed on at least one of the spring seat or the piston. The diaphragm can conform to the one or more grooves of the spring seat thus preventing diaphragm rupture due to excess pressure without affecting calibrations of current PRVCs.

Abstract: A valve assembly includes a flow duct with an inlet and an outlet downstream from the inlet. A piston housing is inside the flow duct and is axially aligned with a center axis of the flow duct. A piston is inside the piston housing and is configured to extend downstream of the piston housing in a closed position. A control chamber is between the piston and an upstream end of the piston housing. A control opening extends through the upstream end of the piston housing and fluidically communicates with the flow duct and the control chamber. A cap extends through the control opening. A cap passage extends through the cap and has an inlet outside of the piston housing and an outlet inside the piston housing, and includes two ninety-degree turns between the inlet and the outlet of the cap passage.

Abstract: A filter includes a first edge structure forming a first ring about an axis. A second edge structure forms a second ring about the axis, axially spaced apart from the first ring along the axis. A filter medium extends from the first edge structure to the second edge structure. The first and second edge structures are configured to engage an internal surface of a main bore of a valve housing. The filter medium is configured to allow air flow through the filter medium from the main bore radially outward through the filter medium to filter particulate out of an airflow from the main bore passing radially outward through the filter medium.

Abstract: A torque transfer arrangement for a butterfly valve includes a crank having a tubular portion with an outer radial surface and an inner radial surface defining a cylindrical bore about a first axis. The tubular portion has two openings connecting the outer surface with the inner surface. A shaft is sized and configured to fit within the cylindrical bore and aligned with the first axis.
