EXTERNAL COMBUSTION ENGINE Russian patent published in 2014 - IPC F01K25/02 

FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises 1^st and 2^nd heat exchangers, 1^st and 2^nd heat carrier valves to feed hot and cold heat carriers, 1^st and 2^nd mechanisms to convert fluid energy into mechanical power, 1^st, 2^nd, 3^rd and 4^th working fluid valves, pipeline to feed working fluid from 1^st heat exchanger, pipeline to feed working fluid from 2^nd heat exchanger, working fluid tank, and pipelines of said 1^st and 2^nd heat exchangers. Said pipelines of said 1^st and 2^nd heat exchangers are arranged in said 1^st and 2^nd heat exchangers, respectively. Outlets of said 1^st and 2^nd heat carrier valves are communicated with inlets of said 1^st and 2^nd heat exchangers. Pipeline with 1^st heat exchanger is connected via working fluid feed pipeline and working fluid 1^st and 2^nd valves is communicated with 1^st and 2^nd mechanisms to convert fluid energy into mechanical power, respectively. Said 1st and 2nd mechanisms to convert fluid energy into mechanical power are communicated with working fluid tank. Pipeline with 2^nd heat exchanger is connected via working fluid feed pipeline and working fluid 3^rd and 4^th valves is communicated with 1^st and 2^nd mechanisms to convert fluid energy into mechanical power, respectively.

EFFECT: simplified design and higher efficiency.
