Patent ID: 8516820

Claim:
A fuel injector assembly for use in a turbine engine comprising a compressor section, a combustion section, and a turbine section downstream from the combustion section, the fuel injector assembly comprising: a flow sleeve defining a pre-mixing passage of the combustion section where fuel is mixed with air before entering a combustion chamber where the mixed fuel and air is mixed with additional fuel from at least one main fuel injector and a pilot fuel injector, the combustion chamber being defined by a liner, said flow sleeve disposed radially outward of the liner, and said pre-mixing passage being defined by said flow sleeve and the liner, said flow sleeve comprising a sleeve wall having a radially inner wall, a radially outer wall, a forward end proximate to a cover plate of the combustion section and an opposed aft end, said flow sleeve including: a cavity portion formed in said aft end of said sleeve wall between said radially inner wall and said radially outer wall and in fluid communication with a source of fuel; a fuel dispensing structure associated with said cavity portion including at least one fuel distribution aperture formed therein for distributing fuel from said cavity portion to said pre-mixing passage; a fuel feed passageway disposed between said radially inner wall and said radially outer wall and comprising an axial passage formed in said sleeve wall; a fuel tube extending through said fuel feed passageway for delivering fuel from said source of fuel to said cavity portion; and a web member coupling said radially inner wall and said radially outer wall and disposed between said fuel tube and said cavity portion, said web member including at least one aperture for delivering fuel from said fuel tube to said cavity portion.
