Abstract

A hybrid labyrinth-brush seal is provided in a flow path between relatively moving parts such as a shaft and a fixed housing. The labyrinth seal includes a plurality of teeth extending radially from one part toward the other providing a labyrinth seal. The brush seal includes generally radially extending bristles in the form of a bristle pack extending generally radially between the teeth of the labyrinth seal toward the rotating part such that the distal ends thereof engage the rotating part.
