  • Patent number: 10428743
    Abstract: A spool and sleeve assembly for a metering valve comprises a spool body defining a center axis, and a sleeve body having a bore that receives the spool body. The sleeve body includes at least one metering window open to the bore and is moveable between a metering position to control flow through the metering window and a shutoff position where flow is prevented from exiting an outlet end of the bore. A seal assembly reacts between the spool body and the sleeve body to provide at least a first sealing interface and a second sealing interface axially spaced from the first sealing interface when the spool body is in the shutoff position. A metering valve for a fuel system is also disclosed.

  • Patent number: 9964223
    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.

  • Publication number: 20180066589
    Abstract: A high pressure relief valve includes a nozzle that is received within an internal bore of a valve housing. The nozzle has a nozzle body with a bore defined by an outlet bore inner diameter that is less than an inlet bore inner diameter. The nozzle body has a nozzle face defined at the outlet end, and is defined between the outlet bore inner diameter and an outlet bore outer diameter spaced radially outwardly of the outlet bore inner diameter. The nozzle body includes a coupling feature held fixed relative to the nozzle body such that the coupling feature is not moveable relative to the nozzle body. The coupling feature is configured to couple the nozzle body to the closure sleeve that surrounds the outlet end. At least one retaining feature prevents the coupling feature from being uncoupled from the closure sleeve.
