Abstract
A regenerator seal assembly for use in a rotary regenerator includes a two-stage seal with a peripheral rim seal having a seal leaf turned inside out so that the free end of the leaf is of a smaller radius of curvature than the fixed end of the leaf and wherein the outer peripheral rim seal is made up of a plurality of straight leaf segments formed on chord lines along the outer circumference of the seal assembly with each straight leaf segment being joined by a mitered joint so that the free end of each such leaf segment is deflected without formation of waviness of wrinkles in the seal assembly.
