Abstract
A seal for effecting a seal between two components (2,4) to inhibit a flow of fluid, between the two components, in a sealing direction (22) from an upstream side (24) of the seal to a downstream side (26) of the seal. The downstream side (26) of the seal in use being at a lower pressure than the upstream side (26) of the seal. The seal comprising a carrier (12) adapted for mounting from one of the components (4), and a plurality of densely packed resilient strips (6) mounted on the carrier (12) to extend therefrom. Each strip (6) having a tip (20) which is adapted to wipe on the other component (2) to effect a seal thereagainst in the sealing direction (22) with the strips (6) arranged substantially parallel to the sealing direction (22). The seal being characterized in that there is provided a gap (30) between adjacent strips to allow the tip portions (20) of the strips (6) to move relative to each other and maintain in use a flexible seal. In order to provide the gap between strips the strips can be tapered, bent, or curved. Alternatively a spacer strip 7 may provided between strips 6.
