Patent ID: 8167314

Claim:
An annular face seal arrangement for a gas turbine engine, comprising: a mounting ring having an overall width extending between a first axial end and a second axial end, and a radial outer surface that extends between the first axial end and the second axial end; a mounting member having a clamp portion and a biasing portion, which clamp portion axially extends between a first clamping surface and a second clamping surface, which biasing portion includes a first segment and a second segment, which second segment has a width and a rotor contact surface; a rotor having a rotor seal surface and a clamp portion having a width; and a stator having a stator seal surface, wherein the stator seal surface is aligned with the rotor seal surface; wherein the mounting ring is disposed radially inside of the rotor and radially inside of at least part of the biasing portion, and is disposed in direct contact with the clamp portion of the mounting member, and the rotor contact surface of the biasing portion is disposed in contact with the rotor; and wherein the sum of the width of the second segment of the biasing portion and the width of the clamp portion of the rotor is greater than the overall width of the mounting ring, and the biasing portion is biased against the rotor.
