Abstract
An exemplary turbomachine seal assembly includes a ring seal that has a radially-facing sealing surface, an axially-facing sealing surface, and a first tapered surface. The turbomachine seal assembly also includes a spacer that has a second tapered surface. The second tapered surface interfaces with the first tapered surface to bias the radially facing sealing surface and the axially facing sealing surface toward a sealing position.
Claims23
A turbomachine seal assembly comprising:
- a ring seal that has a radially-facing sealing surface, an axially-facing sealing surface, and a first tapered surface;
- and
- a spacer that has a second tapered surface, wherein the second tapered surface interfaces with the first tapered surface to bias the radially-facing sealing surface and the axially-facing sealing surface toward a sealing position, wherein the spacer includes a plurality of slots extending from a radially innermost face of the spacer to a radially outermost face of the spacer.
A turbomachine sealing assembly comprising:
- a rotor assembly that establishes a circumferential groove;
- a ring seal at least partially received within the circumferential groove;
- and
- a spacer at least partially within the circumferential groove, the spacer holding the ring seal in a sealed position that limits flow of a fluid from a first axial side of the circumferential groove to a second opposite axial side of the circumferential groove, wherein the spacer provides a plurality of slots that communicate some of the fluid from a first radial side of the spacer to a second radial side of the spacer.

A turbomachine rotor assembly sealing method including:
- positioning a seal at least partially within a circumferential groove of a rotor assembly;
- wedging a spacer to bias the seal radially and axially;
- limiting flow of a fluid past the groove using the seal;
- and
- communicating some of the fluid from a first radial side of the spacer to an opposing second radial side of the spacer within the circumferential groove.
