Patent ID: 7854120

Claim:
A fuel conveying member of a gas turbine engine fuel system conducting pressurized fluid flow, the fuel conveying member comprising a one-piece body defining an L-shaped fuel flow passage internally extending at least partially therethrough, the fuel flow passage having first and second passage portions disposed transverse relative to each other and extending away from an elbow therebetween, the elbow linking and providing communication between the first and second passage portions, the elbow including a transition edge defined at an intersection of inner wall surfaces of said first and second passage portions, said transition edge being radiused, the first passage portion being in fluid-flow communication with an entrance of said body and having a first internal cross-sectional area and the second passage portion being in fluid-flow communication with an exit of said body and having a second internal cross-sectional area, the second internal cross-sectional area having a size different from that of the first internal cross-sectional area, the first internal cross-sectional area being substantially circular and the second internal cross-sectional area being substantially rectangular, and said elbow providing a first substantially smooth fluid-dynamic transition between said first and second passage portions.
