Abstract
A fuel injector for a gas turbine engine may include an injector housing extending along a longitudinal axis and configured to be fluidly coupled to a combustor of the turbine engine. The fuel injector may also include a flow path for a fuel air mixture to the combustor extending longitudinally within the injector housing, and a gallery for liquid fuel encircling the flow path. The gallery may include a plurality of fuel spokes that are configured to deliver liquid fuel from the gallery to the flow path. The gallery may extend from a feed end to a terminal end that overlaps the feed end. The feed end may be a region where liquid fuel enters the gallery and the terminal end may be a region where the gallery terminates.
