Patent ID: 7445212

Claim:
A brush seal for sealing a rotor with respect to a stator, comprising: bristles including free ends oriented toward a first one of the rotor and the stator; and a bristle housing, the bristles fastened in the bristle housing, the bristle housing press-fit in an axial space between a fastening element and a second one of the rotor and the stator, the bristle housing press-fit on the second one of the rotor and the stator against movement in a radial direction relative to the second one of the rotor and the stator, the bristle housing including a cover plate having an outer side surface arranged on a first axial side of the bristles and an axial section that extends axially from the outer side surface in an axial direction away from the bristles toward the first axial side to a free end disposed on the first axial side of the bristles, a supporting plate having an inner side surface arranged on a second axial side of the bristles opposite the first axial side, and a circumferential section that extends from the inner side surface in the axial direction from the second axial side of the bristles to the first axial side of the bristles and axially beyond the free end of the cover plate to a flanged section, the flanged section spaced apart from the free end of the cover plate and projecting radially inwardly beyond the free end of the cover plate so as to form an undercut between the flanged section, the free end of the cover plate, and the outer side surface, the flanged section having a free end that does not directly contact the cover plate, the bristles being fastened in the bristle housing between the inner side surface and the outer side surface; an integral projection provided on the supporting plate; and a recess provided on one of the rotor, the stator and the fastening element; wherein the integral projection and the recess are configured to interact with each other in a positive-locking manner to maintain the press-fit against movement in a radial direction and to provide definite positioning of the bristle housing so as to prevent relative rotation and reversed mounting of the entire bristle housing.
