    • A fuel injector for a gas turbine engine has an inlet fitting, a fuel nozzle, and a housing stem with a pair of fuel conduits fluidly interconnecting the nozzle and fitting. The fuel nozzle includes an annular secondary fuel passageway directing fuel from one fuel conduit to an annular discharge orifice at a discharge end of the nozzle. The secondary fuel passageway is defined between an outer, annular fuel conduit portion and a primary adapter. The primary adapter has an outer surface with a distinct, radially-outwardly-projecting annular shoulder to restrict flow through the secondary passageway and provide substantially uniform distribution of flow through the passageway downstream of the shoulder, for improved combustion and flame stability.
    • 用于燃气涡轮发动机的燃料喷射器具有入口配件,燃料喷嘴和具有流体地互连喷嘴和配件的一对燃料管道的壳体杆。 燃料喷嘴包括将燃料从一个燃料管道引导到在喷嘴的排放端处的环形排放孔的环形二次燃料通道。 二次燃料通道限定在外部环形燃料导管部分和主适配器之间。 主适配器具有外表面,其具有不同的径向向外突出的环形肩部,以限制流过次级通道的流动并且提供通过肩部下游的通道的流体的基本上均匀的分布,以改善燃烧和火焰稳定性。
