  • LABYRINTH SEAL
    Publication number: 20120025472
    Abstract: A labyrinth seal has a plurality of arcuate labyrinth seal segments 14 in which the confronting ends of adjacent arcuate labyrinth seal segments 14 have planar faces 26 which are oriented radially and axially but which are canted away from a strictly axial orientation 28 by a cant angle. A plurality of arcuate brush seal segments 16 may be retained in the plurality of arcuate labyrinth seal segments 14, thereby forming a combined labyrinth and brush seal.
