  • Publication number: 20200040901
    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.

  • Publication number: 20200040902
    Abstract: A bleed valve includes a housing with an inlet coupled to an outlet by a duct. A guide tube is fixed within the housing between the inlet and the outlet. A piston with a piston orifice is slideably supported on the guide tube and movable between an open position and a closed position. The duct fluidly couples the inlet to the outlet in the open position, the duct fluidly separates the inlet from the outlet in the closed position, and the piston orifice fluidly couples the inlet with the outlet in the open position and the closed position to move piston between the open position and the closed position according to differential in pressure between the inlet and the outlet of the bleed valve. Compressors, gas turbine engines, and methods of controlling fluid flow are also described.

  • Publication number: 20200032918
    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.

  • Patent number: 10513977
    Abstract: A valve assembly includes a piston housing inside a flow duct between an inlet and an outlet so as to form an annular flow passage between the flow duct and the piston housing. The piston housing 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 spring biases the piston to the open position. A fluid 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 fluid chamber. A control piston and a control spring are inside the piston housing. The control spring biases the control piston toward a first position that obstructs the control opening.

  • Patent number: 10473225
    Abstract: A passive in-line valve configured to be actuated without an external control includes a valve housing defining an inlet, an outlet, and a flow path between the inlet and the outlet and a piston housing extending inwardly from the housing. The valve includes a valve piston movably disposed within the piston housing, the valve piston including an upstream side and a downstream side. The valve also includes a control mechanism disposed at least partially within the housing and configured to port outlet static pressure to the upstream cavity in a first state such that pressure is equalized on the valve piston.

  • Publication number: 20190301624
    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.
