L BRUSH SEAL FOR TURBOMACHINERY APPLICATION

摘要

The present invention relates to a seal device between a radially-opposed rotating component and a stationary component in a turbomachine. The seal device includes a first rotating component, a second stationary component, and a brush seal located radially between the components. The brush seal has an axially-extending portion secured to the second stationary component, and an inwardly-extending portion extending across a gap between the first component and the second component. An inner ring portion of the second stationary component is located inside the brush seal and is coupled to the axially-extending portion and at least a part of the inwardly-extending portion of the brush seal, wherein an end of the axially-extending portion of the brush seal remote from the inwardly-extending portion is sandwiched between a pair of side rails fixed between the inner ring portion and an outer ring portion of the second stationary component.
