A plurality of arcuate brush seal segments are disposed in radially inwardly opening grooves of a stationary component, enabling tips of the brush bristles to engage the surface of a rotating component. A leaf spring is welded at one end to each brush seal segment and has first and second circumferentially extending curved portions. The first curved portion extends lengthwise of the spring from the welded end to engage the base of the groove at a location intermediate the length of the spring. The second curved portion engages the radial outer face of the segment adjacent the tip of the spring. All of the segments are thus biased for movement radially inwardly toward the rotating component, enabling pressure forces during operation to maintain the brush seal segments properly located to ensure the seal.
