HEAT ENGINE Russian patent published in 2014 - IPC F03G7/06 

FIELD: engines and pumps.

SUBSTANCE: proposed engine comprises working chambers and pistons. Working chambers are filled with heat-sensitive working medium to feed heat from external source. Pistons are fitted inside working chambers to reciprocate there inside and furnished with rods and mechanism to convert their liner reciprocation into rotation of working wheels. Said working wheels transmit rotation to electric power generator shaft. Besides, it comprises extra external source of cold, at least two working chambers and two working wheels. Every said working chamber is composed of vertical cylinder from heat conducting material and arranged inside tight casing. Said casing allows alternate feed of cold and hot fluid therein. Liquid working medium features heat expansion factor higher than that of working chamber walls. Said working gear wheels are fitted aligned on appropriate rods to engage therewith in up travel of rods from working chambers and to turn relative thereto in down travel of rods into working chambers. For this said working wheels are engaged with rods via ratchet gear. Wheels rims engage with vertical spline shaft. Said shaft engages with electric power generator shaft.

EFFECT: higher efficiency.
