A regenerator seal assembly including a flat platform having a wear face slidably engaging a matrix disc and an opposite seal face, a plurality of naturally planar thin and flexible metal strips arrayed in end-to-end overlapping relationship on a bevel surface of the engine adjoining the matrix disc with an outer edge of each strip engaging the platform seal face and forming a gas seal thereat, an elastomeric seal element in a groove in the bevel surface engaging a high pressure side of each metal strip to define a gas seal between the elastomeric element and the metal strips, and a retaining shoe engaging a low pressure side of each metal strip and pressing the latter against the elastomeric element with sufficient force to effect the aforesaid gas seal but with insufficient force to rididly attach the metal strips to the bevel surface. The metal strips slide relative to the bevel surface when the gap between the matrix disc and the engine changes due to thermal distortion of the disc so that stress concentrations in the metal strips are avoided.
