ABSTRACT:
A rotary engine includes a rotor with a plurality of working surfaces. Each working surface of the rotor includes a recess covered by an insulating plate. A ledge is formed within and part way around a periphery of the recess and across one end of each recess. A slot extends into the rotor adjacent the other end of each recess. The plate is supported by the ledge and has one end fixed to a corresponding end of the recess. The other end of each plate is slidably received in the slot so that the plate is spaced apart from a bottom surface of the recess, thus forming an insulating air space or chamber between the plate and the body of the rotor. A small vent through the plate prevents pressure changes within the chamber from deforming the plate.
