Abstract: A metering valve spool controls a volume of fuel passing through a metering valve. The spool has a forward face. A line from a pump has a connection into a chamber. The face of the metering valve spool may contact a seal to block flow into the chamber. The metering valve is connected to a pressure regulating valve. The pressure regulating valve is to be connected to a combustor. A control selectively moves the metering valve spool to control a volume of fuel delivered from the chamber to the pressure regulating valve. The control is also programmed to move the metering valve spool to a position where a forward face of the metering valve spool seals on the seal to block flow from the pump from reaching the pressure regulating valve, and also from reaching the tap. A gas turbine engine is also disclosed.

Abstract: A fiber bundle cartridge for a fiber membrane degassing system includes an inner sleeve including one or more perforations and a fiber bundle positioned radially outward from the inner sleeve. The fiber bundle has an annular shape defining a central bundle axis. The perforations of the inner sleeve define a plurality of inlets and/or outlets facing radially with respect to the central bundle axis. A fiber membrane degassing system includes a housing defining a cylindrical volume having at least one inlet and at least one outlet. The system includes at least one fiber within the cylindrical volume, where fluid flowing through the cylindrical volume from the at least one inlet to the at least one outlet flows perpendicular to a longitudinal dimension of the fiber. A method of degassing a liquid includes directing a liquid volume through a fiber bundle in a direction radial to a longitudinally extending bundle axis.

Abstract: A fluid metering valve includes a flow circuit defined by the valve and a valve member disposed in the flow circuit, the valve member having a sealing portion and configured to be moved by a solenoid between a closed position and one or more open positions. The valve includes a seat member defining one or more fluid outlets, the seat member configured to receive the sealing portion in the closed position to seal the fluid outlets, and an internal porting path defined through the sealing portion that is configured to fluidly connect a downstream side of the sealing portion with an upstream portion of the flow circuit in the closed position to reduce the effective pressure area of the valve member.

Abstract: A bleed valve assembly includes a flow duct with an inlet and an outlet disposed downstream from the inlet. The outlet is smaller in cross-sectional area than a region of the flow duct disposed between the inlet and the outlet. A piston housing is disposed inside the flow duct between the inlet and the 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. At least one rib extends between the flow duct and the piston housing. A sleeve piston is disposed inside the piston housing and is configured to extend downstream of the piston housing in a closed position. The sleeve piston comprises an outer wall that is at least the same in cross-sectional area as the outlet of the flow duct.

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.

Abstract: A bleed valve for a gas turbine engine compressor has a valve body and a flapper. The valve body defines a flow path and includes a flapper seat. The flow path extends through the valve body. The flapper is pivotally connected to the valve body and is movable between a closed position and an open position. In the closed position the flapper seats against the flapper seat and blocks the flow path. In the open position the flapper is angled towards the valve body inlet such that fluid moving through the valve body exerts force on the flapper, urging the flapper towards the closed position.

Abstract: A system includes a flow inlet conduit and a primary conduit that branches from the flow inlet conduit for delivering flow to a set of primary nozzles. An equalization bypass valve (EBV) connects between the flow inlet conduit and a secondary conduit for delivering flow to a set of secondary nozzles. The EBV is connected to an equalization conduit (EC). A pressure equalization solenoid is connected to the EC to selectively connect a servo supply pressure conduit and/or a return pressure (PDF) conduit into fluid communication with the EC. An EBV rate limiting orifice (RLO) is connected in the PDF conduit. A bypass conduit branches from the PDF conduit on a first side of the EBV RLO and reconnects to the PDF conduit on a second side of the EBV RLO. An orifice bypass valve (OBV) is connected to the bypass conduit and acts to selectively bypass the EBV RLO.
