ABSTRACT:
A rotary piston engine is provided which is suitable for working or conveying media in the form of hot deposit-forming gases or vapors. The engine comprises a housing and a rotor mounted rotatably within the housing. The clearance between the rotor and the housing increases as the engine temperature decreases and decreases as the engine temperature increases. This can be achieved by making the rotor of a material having a higher coefficient of expansion than the material of the housing, and/or by cooling the rotor to a lesser extent than the housing.
