Active purge mechanism with backflow preventer for gas turbine fuel injectors

Active purge mechanism with backflow preventer for gas turbine fuel injectors

A fuel injector (100) for a gas turbine engine includes an injector body having a feed arm (130) with a nozzle body (135) mounted thereto. A fuel conduit (310) fluidly connects a fuel inlet portion of the feed arm to a fuel circuit (120) in the nozzle body to form a fuel path through the injector bo...

description A fuel injector (100) for a gas turbine engine includes an injector body having a feed arm (130) with a nozzle body (135) mounted thereto. A fuel conduit (310) fluidly connects a fuel inlet portion of the feed arm to a fuel circuit (120) in the nozzle body to form a fuel path through the injector body and an insulative gap (305) is defined between the fuel conduit and an inside of the feed arm wall to thermally insulate the fuel path of the injector body. An aperture (205) through the feed arm wall provides fluid communication between the insulative gap and ambient conditions existing on an outside of the feed arm wall.
