A thermal regenerator of the kind having a rotary disc-type matric enclosed in a casing traversed by two segregated flows of gaseous heat-exchanging fluids is equipped with an annular flexibly mounted counterface sealing element which makes rubbing contact with the corresponding face of the matrix, and which, in cross-section, has an asymmetric profile tapering from maximum thickness adjacent to the high-pressure side of the sealing element to minimum thickness at the low-pressure side.
