Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel injector with a premix pilot nozzle.SOLUTION: An apparatus for injecting premixed fuel and air through a center body and into the combustion zone of a gas turbine includes a fuel injector nozzle with a premix pilot nozzle having a plurality of premix passages in fluid communication with an air supply and a fuel supply that premixes air and fuel within the premix passages. The apparatus has either an active or passive fuel feed control. Fuel can be fed to the apparatus either conventionally or as a breech load circuit integrated into an oil cartridge. Fuel can be supplied passively via a fuel channel connecting a swozzle fuel plenum to the premix passages. Alternatively, fuel can be injected from the oil cartridge into the premix passages. 【課題】予混合パイロットノズルを備える燃料噴射器を提供する。【解決手段】中心胴体を通してガスタービンの燃焼域に予混合された燃料と空気を噴射するための装置は、予混合流路内で空気と燃料を予混合する空気供給および燃料供給と流体連通した複数の予混合流路を有する予混合パイロットノズルを備える燃料噴射器ノズルを含む。本装置は、能動的燃料供給制御か受動的燃料供給制御かのどちらかを有する。燃料は、従来的か、またはオイルカートリッジに内蔵された後装式回路としてのどちらかで本装置に供給され得る。燃料は、スウォズル燃料プレナムを予混合流路に接続する燃料チャネルを介して受動的に供給され得る。あるいは、燃料はオイルカートリッジから予混合流路に噴射され得る。【選択図】図１
