Abstract
A brush seal device for sealing a high pressure area from a low pressure area. The brush seal device comprises a plurality of bristles arranged annularly. An annular back plate is positioned concentric to and on the low pressure side of the bristles, the back plate having a recess adapted to delay contact of the bristles with the back plate upon application of the pressure across the brush seal device. A flexible annular front plate is positioned adjacent to and concentric with the bristles on the high pressure side of the bristles. This combination of elements helps to reduce uneven wear of the bristles in a brush seal device and, therefore, helps to prolong the life of such a seal.
