Abstract:
An annular labyrinth/brush seal combination for disposition between a rotatable component having an axis of rotation and another component about said axis, comprising:a plurality of non-rotatable arcuate seal ring segments for forming an annulus about and lying in a plane normal to said axis and between said components, each said seal ring segment including a plurality of arcuately extending radially projecting labyrinth seal teeth axially spaced from one another and an arcuate array of discrete, generally linearly extending bristles secured to said seal ring segment, said array of bristles being disposed between a pair of axially adjacent labyrinth teeth, said bristles extending generally in a plane normal to said axis and terminating in tips for sealing engagement with the rotatable component; each of said seal ring segments having opposite ends along radii thereof for substantial registration with ends of adjoining seal ring segments such that, upon assembly of the seal ring segments into an annulus, the opposed ends of each pair of adjoining seal ring segments lie substantially along a radius of the annulus.
