Brush seal

Abstract

A brush seal (200), comprises: a side plate (207); a back plate (209); and a bristle arrangement (211) between the side plate (207) and back plate (209). At least a portion (215) of the back plate (209) is made from a material that tends not to burr when contacting a rotating component (205). The bristle arrangement could include a plurality of bristles secured together by a joint (325). The entire back plate (309, Fig. 4) could be made from the low coefficient of friction or low wear rate material. In addition, the side plate (307, Fig. 4) could also be made from the low coefficient of friction or low wear rate material. The material allows a reduced clearance between the brush seal (200) and the component (205)engaged by the brush seal (200).
