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.
