Patent ID: 7421842

Claim:
A turbine seal, comprising: a combustor basket; an inner housing having an inner coupler section adapted to be attached to the combustor basket and an inner transition section extending from the inner coupler section at a first end of the inner transition section and continuing to a second end of the inner transition section, the second end being adapted to be attached to a second turbine component, wherein the inner transition section tapers from a second diameter at the second end to a first diameter, which is smaller than the second diameter, at the first end; wherein the inner transition section is formed from a plurality of leaves extending from the inner coupler section to the second end of the inner transition section, and each leaf is separated by a slot; and wherein the inner coupler section includes an inner attachment flange transitioning to a body, the inner attachment flange being generally cylindrical and having a diameter, the body being generally cylindrical and having a diameter, wherein the diameter of the inner attachment flange is less than the diameter of the body, the inner transition section being angled relative to the generally cylindrical body, the inner coupler section engaging the combustor basket such that attachment flange directly contacts the combustor basket and such that the body surrounds and is radially spaced from a portion of the combustor basket such that a cooling fluid flow channel is formed between the body of the inner coupler section and the combustor basket.
