Date Feb. 19, 1998A regenerative, rotary heat exchanger includes a stationary housing; a rotatable rotor in the housing; radially extending partition walls in the rotor separating the rotor into sectors; and a regeneratable mass in the sectors. Axially adjustable sector plates are located in sealing relation with respect to respective axial end surfaces of the rotor into which and out from which two heat exchanging media are directed in counter-flow separated by the partition walls. A flange is fixedly attached to the rotor and extends circumferentially around at least one of the respective axial end surfaces of the rotor, and a sensing device senses a clearance between at least one of the sector plates and the flange. A controller adjusts the clearance to a predetermined size responsive to the sensing device. At least one of the sector plates is provided with at least one projection which projects peripherally beyond a side edge of the sector plate at a position opposite the flange; and the sensing device is mounted on the at least one projection |
