Abstract: A seal assembly including a low flow cloth ring seal having a cloth assemblage is provided for sealing a tubular cavity disposed between a tubular member and a mating body. The density of the cloth assemblage may be set according to a desired flow rate of gas through the cloth ring seal. In applications where more stiffness and strength is desired, the cloth ring seal may include a shim assemblage surrounded by the cloth assemblage.

Abstract: A gas-path leakage seal for generally sealing a gas-path leakage-gap between spaced-apart first and second members of a gas turbine (such as combustor casing segments). The seal includes a generally imperforate foil-layer assemblage which is generally impervious to gas and is located in the leakage-gap. The seal also includes a cloth-layer assemblage generally enclosingly contacting the foil-layer assemblage. In one seal, the first edge of the foil-layer assemblage is left exposed, and the foil-layer assemblage resiliently contacts the first member near the first edge to reduce leakage in the "plane" of the cloth-layer assemblage under conditions which include differential thermal growth of the two members. In another seal, such leakage is reduced by having a first weld-bead which permeates the cloth-layer assemblage, is attached to the metal-foil-layer assemblage near the first edge, and unattachedly contacts the first member.
