Abstract
A fuel injector is provided for a turbine engine. This fuel injector includes a fuel nozzle. The fuel nozzle includes a feed passage, a first exit passage and a gallery. The feed passage extends in the fuel nozzle to a feed passage location along the gallery. The first exit passage extends in the fuel nozzle to a first exit passage location along the gallery. The gallery extends in the fuel nozzle circumferentially about an axis from a first end of the gallery to a second end of the gallery. A size of the gallery decreases and then increases as the gallery extends circumferentially about the axis away from the feed passage location and towards the first exit passage location.
