Patent ID: 7942002

Claim:
A fuel manifold assembly configured for mounting internally of a gas turbine engine, the fuel manifold assembly comprising: an annular fuel manifold ring having first and second channels formed in one or more outer surfaces thereof and providing the flow communication between a fuel source and spray tip assemblies of the fuel manifold assembly, the lateral outer surface extending generally radially relative to a central axis of the annular fuel manifold ring, each channel defined by a pair of spaced apart lateral walls facing one another and a channel base recessed from the lateral outer surface, each channel extending substantially circumferentially about the annular fuel manifold ring, the spaced apart lateral walls being substantially parallel to the central axis, and each channel having a depth between the lateral outer surface and the channel base along a depth axis that is substantially perpendicular to said lateral outer surface; a first sealing member having an inner surface, an outer surface and a pair of opposed side surfaces, the first sealing member being disposed within the first channel with the inner surface abutting the channel base or a shoulder bordered by the spaced apart walls without being joined thereto and with the side surfaces parallel to the spaced apart walls, the first sealing member sealingly enclosing the first channel to define at least a first fuel conduit with at least part of the inner surface defining a wall of the first fuel conduit, and wherein the side surfaces of the first sealing member are fastened to the spaced apart lateral walls of the first channel within the annular fuel manifold ring, to define fastened joints between the side surfaces of the first sealing member and the lateral walls of the first channel which extend solely parallel to the depth axis such as to withstand substantially only shear loads when a fluid pressure is applied within the first fuel conduit; and a second sealing member having an inner surface, an outer surface and a pair of opposed side surfaces, the second sealing member disposed within the second channel and sealingly enclosing the second channel to define a second fuel conduit, the opposed side surfaces of the second sealing member are fastened to spaced apart lateral walls of the second channel and defining fastened joints between the opposed side surfaces of the second sealing member and the lateral walls of the second channel which extend solely parallel to a depth axis thereof such as to withstand substantially only shear loads when a fluid pressure is applied within the second fuel conduit, and wherein the outer surfaces of the first and second sealing members form at least a portion of an outer surface of the fuel manifold ring.
