Abstract
A carbon seal assembly for a gas turbine engine is disclosed. The carbon seal assembly includes a first carbon seal. The carbon seal assembly also includes a first carbon seal spring configured to provide force against the first carbon seal in a first axial direction, the first carbon seal spring having an annular shape and circumferentially disposed around a first shaft of the gas turbine engine.
Claims8
A gas turbine engine comprising:
- a first carbon seal configured to form a seal against a first rotating shaft of the gas turbine engine, wherein the first rotating shaft has a first diameter;
- a second carbon seal configured to form a seal against a second rotating shaft of the gas turbine engine, wherein the second rotating shaft has a second diameter that is different than the first diameter;
- a mating hardware disposed between the first carbon seal and the second carbon seal;
- a first carbon seal spring configured to provide force against the first carbon seal in a first axial direction and provide force against the mating hardware in a second axial direction opposite the first axial direction, the first carbon seal spring having an annular shape and circumferentially disposed around the first rotating shaft of the gas turbine engine;
- and
- a second carbon seal spring having the annular shape, circumferentially disposed around the second rotating shaft of the gas turbine engine, and configured to provide force against the second carbon seal in the second axial direction and configured to provide force against the mating hardware in the first axial direction.
