US Patent 6869082: Turbine spring clip seal
US 6869082 ยท granted 2005-03-22

Abstract
An improved turbine spring clip seal for directing gases to be mixed with fuel in a combustor basket. The turbine clip seal may include an inner housing and an outer housing. The inner housing or the outer housing, or both, may include one or more tapered leaves forming a portion of the spring clip seal. At least one leaf may include a flared end for limiting gas from passing through the slots in the spring clip seal. In at least one embodiment, the turbine clip seal may include a center sealing member positioned between the inner and outer housings.

Claim 1
A turbine seal, comprising: an outer housing having an outer coupler section adapted to be attached to a first turbine component and an outer transition section extendingfrom the outer coupler section at a first end of the outer transition section and continuing to a second end of the outer transition section, adapted to be attached to a second turbine component, wherein the outer transition section tapers from a firstdiameter at the first end of the outer transition section to a second diameter, which is larger than the first diameter, at the second end of the outer transition section; the outer transition section formed from a plurality of leaves extending from theouter coupler section to the second end of the outer transition section, wherein at least one second end of at least one leaf has a flared end extending toward adjacent leaves on the outer housing and each leaf is formed by a slot on each side of the atleast one leaf; and an inner housing having an inner coupler section attached to the outer coupler section of the outer housing and an inner transition section extending from the inner coupler section at a first end of the inner transition section andcontinuing to a secon
