Abstract
A brush seal is provided for sealing between a rotating shaft and a housing. The brush seal includes an annular rim or head portion coaxial with the shaft and mounted on the housing, an annular array of bristles extending from the head portion toward the shaft for contact with the shaft at their ends, and an annular bristle support plate extending from the head portion toward the shaft. The support includes voids arranged to accommodate radial deformation in the support due to rubbing contact between the support and the shaft without incurring any substantial accompanying axial deformation which would distort the bristles and cause deterioration of their sealing function.
