ABSTRACT:
A brush seal for use with a housing and sealing a high pressure area from a low pressure area is provided. In an embodiment, the brush seal includes a retainer and a plurality of bristles. The retainer is comprised of a thermally-sensitive material having a thermal expansion rate. The bristles are connected to and extend from the retainer. In an embodiment, the retainer is not fixedly connected to the housing, and the thermal expansion rate of the retainer is greater than the thermal expansion rate of a portion of the housing adjacent the retainer. In another embodiment, a joint associated with a plurality of bristles is permitted to move into a headspace provided above the joint. A method for making a control-gap brush seal assembly for use in connection with a shaft is also disclosed.
