POWER PLANT Russian patent published in 2008 - IPC F02B53/14 F01C11/00 

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention relates to power plants with rotary internal combustion engines. Proposed power plant contains rotary internal combustion engine with fixed body provided with exhaust port and combustion chamber made in body space with rotor with at least one cutoff fitted on output shaft. Plant contains energy recoverer which has fixed housing with input which has fixed housing with input and output ports, and expansion chamber in housing space which accommodates rotor with at last one cutoff fitted on output shaft. Said combustion chamber and expansion chamber communicate with each other and with atmosphere through said ports. Engine is furnished with at least one additional combustion chamber with additional exhaust port and with part of cutoffs per each combustion chamber. Plant contains at least one additional recoverer whose expansion chamber communicates with additional combustion chamber. Number of cutoffs of engine exceeds number of cutoffs of recoverer. Output shafts are interconnected by transmission with gear ratio equal to ratio of indicated cutoffs. Rotors of engine and recoverer can be installed on coaxial shafts. Rotors of engine and recoverer can be installed on parallel shafts. Plant can be furnished with at least one additional engine in which each combustion chamber communicates with expansion chamber on one of said recoverer through additional input ports of recoverers.

EFFECT: increased efficiency, specific power output and reliability of plant.
