ROTARY PISTON ENGINE WITH HEAT FED FROM OUTSIDE Russian patent published in 2010 - IPC F01C1/77 F02G1/44 

FIELD: engines and pumps.

SUBSTANCE: invention relates to engine production. Rotary piston engine comprises two working assemblies each furnished with cylinder housing two rotors revolving therein. Output shafts of rotors are articulated with the device intended for converting oscillatory motion of rotors into rotation. Hot pipeline with heater and cold pipeline with cooler are communicated with working assembly cylinders. Converting device comprises two conversion units, each including main hollow drive shaft accommodating additional hollow drive shaft, cam representing a shaped flat plate, disk rigidly fixed on driven shaft and disk rigidly secured on driven shaft in axial alignment. Said disk has four guides representing identical straight through cuts, rhomb-like four-bar linkage with four pins arranged axially in its apices, passing through disk guides to rest on the cam outer edge. Said linkage has also tow pairs of levers. Levers of the first pair are rigidly jointed with the main drive shaft, while those of the second pair are rigidly jointed with additional drive shaft. Other ends of said levers are articulated to the centers of opposite sides of aforesaid four-bar linkage. All shafts of working assemblies are aligned with aforesaid conversion device shafts. Note here that output shaft of the first rotor is linked up with the main shaft of appropriate conversion device. Output shaft of the second rotor of working assembly is linked with additional drive shaft of appropriate conversion device. Note also that driven shaft is common for both said conversion devices.

EFFECT: higher reliability and efficiency, regulated output shaft torque.
