摘要： A brush seal assembly is provided, including a sealing surface, a side plate, a backing plate, a plurality of bristles, and a biasing member. The backing plate is selectively located in a stationary position and has at least one backing tooth and a backing tip. The backing tooth has a tooth surface and the backing tip has a tip surface. A tooth clearance is measured between the tooth surface and the sealing surface. A tip clearance is measured between the tip surface and the sealing surface. The tooth clearance is less than the tip clearance. The bristles are located between the side plate and the backing plate. The bristles include an end portion for sealing to the sealing surface. The biasing member exerts a biasing force upon the backing plate in a direction towards the sealing surface. The backing tooth is configured for selectively contacting the sealing surface.

摘要： A sealing assembly for use with a rotating machine is described herein. The rotating machine includes a stator casing that includes a radially inner surface that defines a cavity therein, and a rotor positioned within the cavity and spaced inwardly from the stator inner surface. The sealing assembly includes a support ring coupled to the stator casing, and a plurality of plate members coupled to the support ring and oriented circumferentially about the rotor. A resistance member extends inwardly from the support ring towards the rotor outer surface. The resistance member is coupled to the support ring and extends through each plate member of the plurality of plate members. At least one rotor land is defined circumferentially about the rotor outer surface. Each plate member is oriented adjacent the at least one rotor land.
