Abstract
A fuel distribution apparatus has a manifold head, a waisted portion and a nozzle head. An inlet channel is formed in a mounting surface of a casing of a jet engine. An annular inlet manifold is formed in the manifold head to receive fluid from the fuel inlet channel. Six outlet fluid passageways extend substantially tangentially away from the annular inlet manifold and open out into an annular outlet manifold. Three ports are formed in the inner wall of the annular outlet manifold and the ports are connected to fuel delivery tubes which extend away from the ports in a substantially helical fashion around the waisted portion into a nozzle head. The outlet fluid passageways are arranged to direct the fluid around the outlet manifold in a first direction and the helical fuel delivery tubes extend in the opposite direction.
