ABSTRACT:
A brush seal assembly for effecting a seal between two relatively movable machine components has a carrier for moving on one component (12) and having two spaced rows (16 and 17) of bristles projecting towards the surface of the other component (11) to be sealed to said one component (12). Backing plates (18 and 19) are provided on the low pressure side of each row (17 and 18) of bristles respectively. The physical characteristics of the bristles of each row are selected to share the total pressure drop between the two rows of bristles, and preferably to be equally shared.
