L-brush seal for turbomachinery applications

摘要

A seal assembly between a rotating and a radially opposed stationary component in a turbomachine includes a rotating first component, a stationary second component and a brush seal disposed radially therebetween. The brush seal has an axially extending portion secured to the stationary second component and an inwardly extending portion extending across a gap between the first and second components. An inner annular portion of the stationary second component is disposed radially inward of and into engagement with the axially extending portion and at least a portion of the inwardly extending portion of the brush seal, with one end of the axially extending portion of the brush seal remote from that of inside extending portion is interposed between a pair of side rails which are fixed between the inner ring portion and an outer ring portion of the stationary component.
