Abstract
Abstract An improved fuel delivery system for the combustor of a gas turbine engine is disclosed. The improvement comprises a combustor support pin, a fuel atomizer, and a tube for delivering fuel to the atomizer. The combustor support pin provides axial support for the combustor and includes a duct therethrough. The fuel delivery tube is removably located within the duct.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
161 words
A gas turbine engine fuel delivery system generally disposed within an annular engine casing comprising: a combustor disposed within the casing and connected to the casing by at least one combustor support pin disposed in a sliding joint in said said combustor for providing axial support for said combustor with respect to the annular engine casing, said pin including a duct therethrough; a fuel atomizer disposed within said combustor; a tube for delivering fuel to said atomizer, said tube being removably located within said duct; and wherein said atomizer includes an annular air passage defined by an annular outer wall with an inner surface and a fuel passage therethrough, a radially, with respect to said annular outer wall, tapered groove having a deep end and a shallow end and formed in and in part defined by said outer annular wall and circumferentially disposed upon said inner surface wherein said fuel passage connects said tube to said deep end of said groove.
Claim 2
Dependent Claim
