摘要： 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.

摘要： An outside diameter brush seal assembly is disclosed. The brush seal assembly includes a first static component, a second static component, and a brush seal. The first and second static components may be configured to form a flow path from a first pressure cavity to a second pressure cavity. The brush seal includes a plurality of bristles that extend in a radially outward direction from the first static component to form a brush seal against the second static component.
