ABSTRACT:
The sealing mechanism for a rotative heat regenerator herein disclosed includes a pair of seal rings fixed to an axle received in the central hole of a disc-shaped rotative heat regenerator core. Each seal ring has a boss provided in the center and inserted over the axle, at least two arms extending outwardly from the boss and rings being attached to the outer ends of the arms and identical in diameter to the heat regenerator. The boss, the arms and the rings are positioned opposite to the center, the side face and the outer periphery, respectively, of the heat regenerator. Each of the boss, the arms and the rings has a sliding member facing either side of the heat regenerator, and the sliding members provided in the rings are slidable along the outer surface of the regenerator. Elastic bodies are interposed between the sliding members and the regenerator surface. Thus, if the side face of the heat regenerator and/or the ring is distorted, excellent sealing can be maintained around the outer surface of the heat regenerator to prevent gas leakage therefrom without requiring an increased driving torque for the regenerator.
