Abstract
The present disclosure relates generally to a sliding seal between two components. The sliding seal includes a first seal section and an adjacent second seal section, each including a base and two extending legs defining respective first and second ends of the seal. At least the first seal section includes a first plurality of slots extending from the first end to the base and a second plurality of slots extending from the second end to the base.
Claims10
A seal for sealing a space defined by first and second adjacent components disposed about an axial centerline, the seal comprising:
- a first seal section including a first base, a first leg extending from the first base and defining a first distal end, and a second leg extending from the first base and defining a second distal end;
- and
- a complimentary second seal section disposed adjacent the first seal section, the second seal section including a second base, a third leg extending from the second base and a fourth leg extending from the second base;
- wherein the first seal section includes a first plurality of slots extending from the first end to the first base and a second plurality of slots extending from the second end to the first base;
- wherein the second seal section includes a third plurality of slots extending from the first end to the second base and a fourth plurality of slots extending from the second end to the second base;
- wherein each of the first plurality of slots is circumferentially offset from each of the third plurality of slots and each of the second plurality of slots is circumferentially offset from each of the fourth plurality of slots;
- wherein the first seal section is configured to sealingly engage with the first and second components;
- a first protrusion disposed on the first leg and located at the first distal end;
- a second protrusion disposed on the second leg and located at the second distal end;
- a third protrusion disposed on the first seal section;
- wherein the seal contacts a first surface of the first component at the first protrusion along a first single substantially circumferential line of contact;
- wherein the seal contacts the second component at the second protrusion along a second single substantially circumferential line of contact;
- and
- wherein the seal contacts a second surface of the first component at the third protrusion along a third single substantially circumferential line of contact.

- 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 extending from the first base and defining a first end, and a second leg extending from the first base and defining a second end;

- wherein the first seal section includes a first plurality of slots extending from the first end to the first base and a second plurality of slots extending from the second end to the first base;
- wherein the second seal section includes a third plurality of slots extending from the first end to the second base and a fourth plurality of slots extending from the second end to the second base;
- wherein each of the first plurality of slots is circumferentially offset from each of the third plurality of slots and each of the second plurality of slots is circumferentially offset from each of the fourth plurality of slots;
- wherein pressure within the seal cavity urges the seal to seat against the first surface and the second surface;
- a first protrusion disposed on the first leg and located at the first distal end;
- a second protrusion disposed on the second leg and located at the second distal end;
- a third protrusion disposed on the first seal section;
- wherein the seal contacts a first surface of the first component at the first protrusion along a first single substantially circumferential line of contact;
- wherein the seal contacts the second component at the second protrusion along a second single substantially circumferential line of contact;
- and
- wherein the seal contacts a second surface of the first component at the third protrusion along a third single substantially circumferential line of contact.
