Repositionable brush seal for turbomachinery

A brush seal assembly (14) is radially and axially repositionable relative to stationary and rotating components (10, 12). Shim packs (62, 66) whose thickness can be reduced by peeling adhesively attached foil layers from the shim packs are used to provide both axial and radial repositioning. In ano...

Zusammenfassung:	A brush seal assembly (14) is radially and axially repositionable relative to stationary and rotating components (10, 12). Shim packs (62, 66) whose thickness can be reduced by peeling adhesively attached foil layers from the shim packs are used to provide both axial and radial repositioning. In another form, a plurality of set screws (60) may be threaded into a mounting member (50) for the brush seal assembly to controllably space the brush seal from the rotating component. In a further form, an eccentric cam is rotated to reposition the brush seal assembly radially inwardly or outwardly with shim packs being used to reposition the brush seal in an axial direction.
