A pressure atomizing fuel nozzle assembly for a gas turbine engine includes a support housing in which a pressure-responsive fuel check valve and metering valve are disposed in line to provide a flow of primary fuel for engine start-up and low power operation and secondary fuel for higher power operation. The check valve is located upstream between the fuel inlet and a sleeve inside of which the metering valve is disposed. The check valve prevents the fuel manifold from draining after engine shut-down and controls fuel entry to both the secondary fuel chamber within the sleeve and to an annular primary fuel chamber between the sleeve and support housing connected in fuel flow relation to the secondary chamber by a fuel filter. The primary fuel flows through the primary chamber around the exterior of the secondary chamber and through an annular primary fuel conduit disposed around the secondary fuel conduit in the housing strut to the nozzle attached to the strut. The secondary fuel flow is controlled by the downstream metering valve in the sleeve and flows interiorly of the primary fuel to the nozzle.

The fluid valve assembly includes a hollow movable valve having an open-ended tubular fluid filter in the longitudinal bore of the valve and overlying transverse fluid discharge passages in the hollow valve to filter fluid before it flows through the transverse discharge passages from inside the valve. Downstream of the tubular fluid filter, the hollow valve includes one or more fluid metering passages which are moved relative to a valve seat to control a second flow of fluid from inside the valve. The increased fluid flow longitudinally in the valve bore when the valve is moved from the seat to effect the second fluid flow exerts a washing action on the tubular fuel filter to remove debris or foreign matter therefrom and carry same out through relatively large fluid passages not prone to clogging.

A fuel nozzle assembly with integral valve for a gas turbine engine includes an inlet fitting with a tubular wash-type fuel filter therein between a central fuel passage and an annular primary fuel manifold therearound to filter primary fuel flowing through the passage to the annular primary fuel manifold chamber on the inlet fitting. The manifold chamber is in fuel flow relation in the valve housing with a primary fuel take-off passage therein for providing primary fuel flow to a fuel nozzle.
