摘要： A metering valve has a shutoff position at which it blocks flow from the metering valve outlet line from reaching an outlet to a use. A spool has a first end and a second end. The housing has a first shoulder associated with the first end and a second shoulder associated with the second end. In the shutoff position, the spool has the first end spaced from the first shoulder, and the second end spaced from the second shoulder. A fuel system for a gas turbine engine is also disclosed.

摘要： 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.

摘要： A transfer valve includes a spool comprising a first circumferential flow channel at a first axial position of the spool and a second circumferential flow channel at a second axial position of the spool. The first circumferential flow channel and the second circumferential flow channel have different circumferential positions and are defined only partially circumferentially, and a sleeve disposed over the spool. The sleeve includes at least three flow windows defined through the sleeve at an axial position of the sleeve, each flow window having different circumferential positions on the sleeve. The spool is configured to translate within the sleeve between a first position and a second position. The first circumferential flow channel of the spool is configured to fluidly connect a first plurality of the at least three windows in the first position, and the second circumferential flow channel is configured to connect a second plurality of the at least three windows in the second position, wherein the first plurality of windows is different by at least one window from the second plurality of windows.

摘要： A multi-bend control circuit for fluid communication with an outlet port of a valve includes a first circuit leg extending in a first direction and a second circuit leg extending at an angle from the first circuit leg in a second direction. A third circuit leg extends at an angle from the second circuit leg in a third direction different from the second direction. A sense line tap is in fluid communication with at least one of the first, second or third legs.

摘要： A flexure includes a flexure body with an inner ring defining a main axis and an outer ring extending about the inner ring that is outboard of the inner ring with respect to the main axis. One or more flexure members having respective lengths that are greater than a radial offset distance defined between the inner ring and the outer ring connects the inner ring to the outer ring. A valve includes a valve member connected to a valve body by the flexure.
