ABSTRACT:
Rotary regenerative heat exchange apparatus including a cylindrical rotor of heat absorbent material that is alternately exposed to a hot and a cold fluid in order that heat absorbed from the hot fluid may be transferred to the cold fluid passing therethrough. The rotor is surrounded by a housing that includes a sector plate at opposite ends thereof to separate the hot from the cold fluids. As the rotor turns and is being subjected to a wide range of temperatures, it distorts into a dish shaped element. A mechanical toggle arrangement moved by a hydraulic actuator forces the sector plate into a configuration similar to that of the adjacent face of the rotor so as to preclude excessive leakage of fluid therebetween.
