Pressure seal with non-metallic wear surfaces

摘要

A gas turbine engine has a pair of components having a high-pressure chamber on one side, and a low pressure chamber on an opposed side. A three-sided seal has one side in sealing contact with each of said components. A third side is associated with a third component. At least one non-metallic wear surface is positioned between one of the three sides of the seal and its respective component.

主权项

1. A gas turbine engine comprising:
a first component and a second component, said first and second components having a high-pressure chamber on one side, and a low pressure chamber on an opposed side, and a three sided seal having one side facing each of said first and second components, and having a third side facing a third component, and there being at least one non-metallic wear surface between one of said three sides of said seal and said facing component; and said three sided seal floating relative to each of said first, second and third components; and such that it is movable relative to each of said components wherein one of said components is a liner segment of an exhaust system in the gas turbine engine.
