Flexible cloth seal assembly

摘要

A seal assembly (110) comprises a flexible cloth seal (112) including a shim assemblage (122) surrounded by a cloth assemblage (124). A first tubular end portion (114), such as a gas turbine combustor, includes a longitudinal axis (134) and has smooth and spaced-apart first and second surface portions (136, 138) defining a notch (140) therebetween which is wider at its top than at its bottom and which extends outward from the axis (134). The second surface portion (138) is outside curved, and a first edge (126) of the cloth seal (124) is positioned in the bottom of the notch (140). A second tubular end portion (116), such as a first stage nozzle, is located near, spaced apart from, and coaxially aligned with, the first tubular end portion (114). The second tubular end portion (116) has a smooth third surface portion (148) which surrounds at least a portion of the first tubular end portion (114) and which is contacted by the cloth seal (112).
