The assembly seals a radial gap 30 between two relatively rotatable coaxial members, e.g. the stator 8, 16 and the rotor 6, 14 of a gas turbine compressor. The stator has a fin portion 20 extending axially with an end flange 28 and the rotor has a radially opposed groove portion 32. The fin portion 20 impedes gas flow between the two members and the groove portion 32 is positioned to disrupt gas flow over the fin portion. In use, the rotating rotor centrifugally widens the gap 30 between it and the fin portion 20. |
