ABSTRACT:
An improved rotary engine including a housing having interior walls defining an operating chamber with a rotor mounted for movement therein. Within the chamber is a thin layer of wear resistant metal which is located to be sealingly engaged by the rotor as the rotor moves within the chamber and a backing is secured to the thin layer in good heat transfer relation and interposed between the same and the housing for transmitting pressure applied to the thin layer to the housing. The backing is formed of a metal having high thermal conductivity and is provided with a plurality of relatively closely spaced coolant passages to provide an improved cooling structure for the engine to thereby extend its life.
