Patent ID: 7389991

Claim:
A sealing arrangement for use in a gas path between two relatively rotatable members of a gas turbine, the sealing arrangement comprising: a pair of coacting leakage seals each having a foil layer and a cloth layer, wherein the foil layer has two expansive surfaces, only a single one of which is covered by the cloth layer, a proximal end, a distal end, and a generally planar region between the proximal and distal ends, wherein the proximal end of one of the coacting seals is attachable to an associated one of the turbine members, the proximal end of the other of the coacting seals is attachable to the other turbine member, and the cloth layer of the coacting seals bear against each other along the generally planar region and the distal end of each coacting seal including both the foil layer and the cloth layer diverging in opposite directions from the generally planar region when the coacting seals are attached to associated turbine members.
