Abstract
A plurality of brush seal segments are disposed in a groove of a component fixed against rotation and project into sealing relation with a rotating component. The brush seal segments are each comprised of a pair of plates having a plurality of brush bristles therebetween, the plates and bristles being secured along the outer arcuate face of the segments by a weld bead. The opposite ends of the bristles form the seal with the rotary component. Each brush seal segments is disposed in a groove with generous clearance between a hook on the segment and a flange on the fixed component. A spring between the fixed component and arcuate outer face of the brush seal segment biases the segment in a radial direction. The end of the spring has a pair of tabs spaced axially from one another for reception in a pair of axially spaced recesses to retain the spring against circumferential movement while simultaneously maintaining the integrity of the weld joint without loss of securement of the bristles.
