FIELD: mechanical engineering; heat engines.
SUBSTANCE: invention relates to displacement heat engines with external supply of heat operating according to thermodynamic Stirling cycle. They can be used in different spheres of machine-building to drive self-contained objects operating under conventional atmospheric conditions. Proposed engine contains at least one ring cylindrical chamber, rotor made in form of face plate with ring cylindrical projection dividing space of chamber into inner and outer eccentric spaces. Blades are installed on hinge joints in longitudinal slots of rotor. Two bypass channels are made in chamber. One of said channels passes through recuperative heat exchanger and it. Communicates interblade volumes. Second bypass channel communicates interblade volumes of spaces at minimum values and it passes through recuperative heat exchanger and external heater. Method of operation of engine is described in invention.
EFFECT: provision of continuous conversion of thermal energy into mechanical energy close to Stirling cycle.
