<p>A brush seal assembly for effecting a seal between a first component (12) and a surface of a second component (11) movable relative to the first component. The assembly has a first row of bristles (17) arranged to be supported by the first component (12) and to extend towards but not touch the surface of the second component (11), and a second row of bristles (19) arranged to wipe over the surface of the second component which second row of bristles (19) lies against one side of the first row of bristles (17). The bristles (17) of the first row are shorter than those of the second row, and have a greater stiffness. The seal assembly includes a backing plate (15) intended to be disposed on the low pressure side of the seal and which supports the adjacent row of bristles. Depending upon the intended use, either the first row or the second row of bristles may be supported by the backing plate (15).</p> |
