Abstract
An arrangement and method for accurately radially locating a brush seal relative to a rotor provides a labyrinth seal segment having a slot open toward the rotor and defining an interior ledge facing away from the rotor, a brush seal segment inserted in the slot and having an exterior shoulder facing toward the rotor and overlying the interior ledge of the labyrinth seal segment such that the brush seal segment can move radially relative to the labyrinth seal segment and rotor and the shoulder of the brush seal segment can move toward and away from the interior ledge of the labyrinth seal segment, and set screws tightened into spaced apart threaded holes in the labyrinth seal segment forcing the shoulder of the brush seal segment against the ledge of the labyrinth seal segment so as to prevent radial floating of the brush seal segment relative to the labyrinth seal segment.
