Sealing arrangement
First Claim
1. A sealing arrangement between first and second annular components (2, 4) having a common axis, the arrangement comprising a sealing ring (20) which, as viewed in cross-section, has a first limb (24) which is slidable within a circumferential groove the first limb (24) and which makes sealing contact with the second component (4), characterised in that the sealing ring (20) is radially resilient, the second limb (26) having a sealing face (30) which is biased by the resilience of the sealing ring (20) into contact with an abutment surface (32) of the second component (4).

Abstract
A sealing arrangement between annular components 2, 4, for example in a gas turbine engine, comprises an L-shaped sealing ring 20. The sealing ring 20 has a first limb 24 received in a groove 28 in the first component 2, and a second limb 26 having a sealing face 30 which is maintained in contact with an abutment surface 32 on the second component 4 under the resilient action of the sealing ring 20. The second limb 26 is exposed to the pressure in a chamber 34 which assists the resilience of the sealing ring 20 in maintaining sealing contact between the sealing face 30 and the abutment surface 32. Bleed holes 38 are provided.
