| 摘要 |
The present invention relates to a heat engine integrating a refrigerant fluid in a closed circuit and intended to undergo changes in pressure and temperature, characterized in that the circuit comprises at least: one evaporation tank (4) positioned in contact with a fluid, outside the engine, moving in a nozzle (3), one liquefier (11) in contact with a fluid capable of absorbing heat and associated with a conduit allowing the liquefied refrigerant fluid to return into the tank (4), and at least one power turbine (15), positioned between the liquefier (11) and the tank (4), and one compressor (9) downstream from the tank (4) in the circuit and arranged for controlling the temperature of the refrigerant fluid by controlling the suction of the evaporated refrigerant fluid, and in that the refrigerant fluid remains at a pressure and temperature of saturating vapor on the whole of the circuit.
