ABSTRACT:
The power-generation system comprises an engine actuated by the expansion a liquefiable gaseous fluid within a chamber which undergoes a cyclic variation in volume, an evaporator supplied from a hot source such as a solar or geothermal heat collector and a condenser associated with a cold source. A driving fluid which is vaporized under pressure in the evaporator is employed at least partly for lubrication of the engine, the liquid elements entrained by the vaporized fluid being collected by means of a separator and conveyed to the engine casing through a drawing-off line.
