Abstract
The present disclosure relates generally to a seal between two circumferential components. The seal comprises a plurality of seal segments disposed adjacent one another by a retaining ring that is at least partially disposed within a cavity formed within each of the plurality of seal segments.
Claims15
A seal for sealing a space defined by first and second circumferential components, the seal comprising:
- a plurality of seal sections, each of the plurality of seal sections having a base extending substantially in an axial direction;
- a first leg extending away from a first planar side of the base substantially in a radial direction;
- and a second leg extending away from the first planar side of the base substantially in the radial direction, the base further including a first substantially rounded end integrally formed with a second planar side of the base and in contact with the first component along a first arcuate line of contact and a second substantially rounded end integrally formed with the second planar side of the base and in contact with the second component along a second arcuate line of contact, wherein the first planar side of the base is opposite and parallel to the second planar side of the base;
- and wherein a cavity is defined between the first and second legs on the first side of the base;
- and
- a retaining ring at least partially disposed within the respective cavities of each of the plurality of seal sections.

A system, comprising:
- a first circumferential component disposed about a centerline and including a first surface;
- a second circumferential component disposed about the centerline and including a second surface, the second circumferential component disposed adjacent the first circumferential component and defining a seal cavity therebetween;
- and
- a seal disposed in the seal cavity, the seal including:
- a plurality of seal sections, each of the plurality of seal sections having a base extending substantially in an axial direction;
- a first leg extending away from a first planar side of the base substantially in a radial direction;
- and a second leg extending away from the first planar side of the base substantially in the radial direction, the base further including a first substantially rounded end integrally formed with a second planar side of the base and in contact with the first component along a first arcuate line of contact and a second substantially rounded end integrally formed with the second planar side of the base and in contact with the second component along a second arcuate line of contact, wherein the first planar side of the base is opposite and parallel to the second planar side of the base;
- and wherein a cavity is defined between the first and second legs on the first side of the base;
- and
- a retaining ring at least partially disposed within the respective first cavities of each of the plurality of seal sections.
