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.
Claims20
A fuel injector for a turbine engine, comprising:
- a fuel nozzle including a feed passage, a first exit passage and a gallery;
- the feed passage extending in the fuel nozzle to a feed passage location along the gallery;
- the first exit passage extending in the fuel nozzle to a first exit passage location along the gallery;
- and
- the gallery extending in the fuel nozzle circumferentially about an axis from a first end of the gallery to a second end of the gallery, and a size of the gallery decreasing and then increasing as the gallery extends circumferentially about the axis away from the feed passage location and towards the first exit passage location.
A fuel injector for a turbine engine, comprising:
- a fuel nozzle including a feed passage, a plurality of exit passage and a gallery;
- the feed passage extending in the fuel nozzle to the gallery;
- each of the plurality of first exit passages extending in the fuel nozzle to the gallery;
- and
- the gallery extending in the fuel nozzle circumferentially about an axis from a first end of the gallery to a second end of the gallery, and a size of the gallery undulating as the gallery extends circumferentially about the axis from the first end of the gallery to the second end of the gallery.
A fuel injector for a turbine engine, comprising:
- a fuel nozzle including a feed passage, a plurality of exit passage and a gallery;
- the feed passage extending in the fuel nozzle to the gallery;
- each of the plurality of first exit passages extending in the fuel nozzle to the gallery;
- and
