Patent ID: 7757494

Claim:
A device for feeding fuel to a combustion chamber in a turbomachine, the device comprising: an annular fuel feed rail that extends around an outer cylindrical casing of the combustion chamber and that is connected to a fuel feed device; a plurality of injectors that are secured to the casing and that opens out into the combustion chamber; angled fuel transport ducts that connect the fuel feed rail to the injectors; and a rail support mechanism that connects the injectors to the fuel feed rail, wherein the rail support mechanism includes a connecting mechanism that is deformable in bending, twisting, and pivoting such that the rail support mechanism allows the casing to expand thermally in a radial direction relative to the annular rail and such that the rail support mechanism provides a rigid support for the annular rail, wherein the connecting mechanism includes at least one traction spring mounted between the rigid tabs that are in alignment with each other and that are spaced apart from each other, and wherein the at least one traction spring is disposed at an angle of about 20 degrees relative to an axis of the casing and slopes outwards from an upstream end of the casing to a downstream end of the casing.
