    摘要: A fuel injector including an injector tip 160 that has annular fuel flow passages and a stem 172 containing at least one fuel flow passage 174 extending from a stem fuel inlet 140 to a fuel delivery outlet 186. A first annular fuel flow cavity 142 provided in the stem near the fuel stem inlet 140, an inlet conduit 144 extends from the fuel stem inlet 140 to the annular cavity 142, the inlet conduit 144 being angled to provide a tangential flow direction to the fuel passing through the conduit 144 to the annular cavity 142. An outlet conduit 146 extends at an acute angle from the first annular cavity 142 to receive the fuel therefrom in a tangential direction. A first linear fuel conduit 148 is provided extending from the outlet conduit 146, extending axially of the stem and communicating with an injector inlet conduit 186 at the fuel delivery outlet. The injector inlet conduit 186 is angled to direct the fuel flow to a first annular passage 168 in the injector tip 160 in a tangential direction to provide a swirl to the fuel flow entering the annular passage 168 in the injector tip 160.

    摘要: A fuel injector (30) for a gas turbine engine of an aircraft has an inlet fitting (36), a fuel nozzle (40), and a housing stem (42) fluidly interconnecting and supporting the nozzle on the fitting. An internal heatshield assembly comprising an internal fuel conduit (140) extends in a bore (82) in the housing stem. An upper end of the fuel conduit has a rigid, fluid-tight connection (142) with a fuel inlet passage in the fitting, while the lower end of the fuel conduit has a rigid, fluid-tight connection (144) with the fuel nozzle. The bore closely surrounds the fuel conduit and a stagnant air gap is provided between the internal walls of the bore and the outer surface of the fuel conduit. The bore can be completely enclosed with a vacuum drawn in the bore, or can be open at its lower end to an air swirler in the fuel nozzle. The fuel conduit can have a single or dual internal fuel flow passages, and a coiled portion (150) within an enlarged cavity in the bore to allow for thermal expansion of the fuel conduit. The fuel injector can be easily assembled with the engine combustor using a flange (90) extending outwardly from the housing stem, and can be easily disassembled for inspection or replacement.

    摘要: A self-purging fuel injector for a combustor of a gas turbine engine is disclosed wherein the fuel injector comprises an injector body (10) having one or more, preferably two, air discharge orifices (122c) for discharging air to the combustor and first (130) and second (150) fuel passage means having respective first (132c) and second (162c) fuel discharge orifices for discharging fuel to the combustor. The first and second fuel passages are in communication upstream of the fuel discharge orifices. If the supply of fuel to the first and second fuel discharge orifices is interrupted, a pneumatic pressure is applied at the first fuel discharge orifice and a different pneumatic pressure is applied at the second fuel discharge orifice such that the fuel residing in the fuel passages between the first and second fuel discharge orifices is subjected to a pressure differential effective to purge the resident fuel into the combustor.
