Fuel supplying device for e.g. jet engine of airplane, has injectors fixed on external cylindrical case and connected to annular ramp by support units of ramp, where support units are deformable by flexion, torsion and rotation

摘要

The device has a fuel supplying annular ramp (18) extending around an external cylindrical case (12) of a combustion chamber and connected to a fuel supplying unit. A set of injectors (20) is fixed on the case and emerges into the chamber. The injectors are connected to the ramp by ducts bended to transport the fuel and by support units (34) of the ramp, where the support units are deformable by flexion, torsion and rotation.
