  • Brush seal
    Patent number: 6173962
    Abstract: A brush seal includes a mounting ring that carries radially inwardly directed bristles. A backing member attached to the mounting ring is positioned alongside the bristles. A chamber defined by the bristles and the backing member is pressurized with fluid to counteract the lateral forces imposed upon the bristles by a region of high fluid pressure that they are operationally adjacent. As a result of this balancing of forces, the bristles are free to move radially inward and outward so that their free ends remain in sealing engagement with an adjacent surface.
