METHOD OF HEAT ENERGY-TO-MECHANICAL POWER CONVERSION AND DEVICE TO THIS END Russian patent published in 2014 - IPC F03G7/06 

FIELD: engines and pumps.

SUBSTANCE: proposed device comprises heat-sensitive actuating medium composed of two heat-accumulating materials arranged in separate heat-insulation cylindrical cases of cold heat exchangers. Said heat-accumulating materials are made from a set of bimetallic coils with RH winding in one heat exchanger and LH winding in another one. Note here that housings of both heat exchangers are connected on both sides by heat carrier feed and discharge rigidly interconnected pipelines. Housings, gates and pump are coupled by mechanical gearing. Proposed method consists in alternate feed of hot and cold heat carrier. Note here that first cold heat exchanger brings hot heat carrier in contact with coil to expand it and accumulate strains to preset magnitude whereat its acts at its cylindrical case to turn it. At a time, processes in second heat exchanger occur ion reverse order.

EFFECT: higher efficiency of conversion.
