CONVERSION METHOD OF HEAT TO HYDRAULIC ENERGY AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC F02G1/43 F03G7/06 F15B1/00 

FIELD: power industry.

SUBSTANCE: conversion method of heat to hydraulic energy involves supply of working liquid to pneumatic hydraulic accumulator with gas compression, further gas expansion with displacement of working fluid from the other accumulator, as well as heat supply to gas and heat discharge from gas, which are performed so that average gas temperature at expansion is higher than at compression. Heat is supplied to gas by moving gas through another colder heat exchanger; at that, gas is moved through the above heat exchangers between various accumulators. Conversion device of heat to hydraulic energy includes at least two accumulators, liquid supply and receiving devices, as well as heating and cooling devices which include at least two flow gas heat exchangers installed with possibility of shifting the gas through them between gas tanks of equal accumulators.

EFFECT: increasing efficiency and speed of heat conversion to hydraulic energy, ensuring reliability and high density and power.
