Patent ID: 6880341

Claim:
A floating collar assembly for damping vibration and sealing between a combustor and a fuel nozzle of a gas turbine engine, the combustor having a nozzle opening with an outer peripheral abutment surface, the nozzle including a body aligned with said nozzle opening, and a shoulder laterally extending from said body, the floating collar assembly comprising: an annular floating collar having a combustor face being in radial sliding engagement with said abutment surface, a central aperture being in axial sliding engagement with the nozzle body, and an outer bearing surface; and biasing means, disposed between the outer bearing surface of the floating collar and an inner surface of the nozzle shoulder, for maintaining sealing engagement, for damping vibration, and for impeding relative rotation between the nozzle and the combustor, while accommodating axial and radial relative displacement.
