Abstract
The present disclosure relates generally to a sliding seal between two components. The sliding seal includes a first seal section and an uncoupled second seal section which allows the first and second seal sections to move relative to one another during relative movement between the two components. A wave spring and/or a rope seal is disposed between the first and second seal sections biases the first and second seal sections away from one another.
Claims15
A seal for sealing a space defined by first and second adjacent components disposed about a centerline, the seal comprising:
- a first seal section including a first base, a first leg and a frustoconical section joining the first base and the first leg;
- and
- a second seal section including a second base and a second leg extending from the second base;
- wherein the first and second seal sections are configured to sealingly engage with the first and second components;
- a rope seal disposed between the first and second seal sections and operative to bias the first seal section and the second seal section away from one another;
- and
- wherein the first and second seal sections are configured to move relative to one another.

A system, comprising:
- a first component including a first surface;
- a second component including a second surface, the second component disposed adjacent the first component and defining a seal cavity therebetween;
- wherein the first and second components are disposed about an axial centerline;
- and
- a seal disposed in the seal cavity, the seal including:
- a first seal section including a first base, a first leg and a frustoconical section joining the first base and the first leg;
- and
- a second seal section including a second base and a second leg extending from the second base;
- wherein the first and second seal sections are configured to sealingly engage with the first and second components;
- a rope seal disposed between the first and second seal sections and operative to bias the first seal section and the second seal section away from one another;
- and
- wherein the first and second seal sections are configured to move relative to one another;
- and
- wherein pressure within the seal cavity urges the seal to seat against the first surface and the second surface.
