PURPOSE:To obtain a prime mover free from environmental pollution by allowing high temperature liquid to be inhaled into the lower part of the cylinder vessel of the prime mover which utilizes gas expansion as energy source and driving the liquefied natural gas into the liquid in a proper grain size from a penetration hole and taking-out the evaporation expansion pressure by means of a piston. CONSTITUTION:A suction valve 6 is opened to absorb seawater W into a vessel 1 from a seawater line 5, and a piston 2 is raised when a prescribed amount of seawater W is absorbed into the vessel 1, the suction valve 6 is closed, and a proper amount of the gaseous phase part is formed on the liquid surface W. LNG in a proper grain size is driven into the seawater W, by an LNG driving apparatus 8 passing through the gaseous phase. The LNG in contact with the seawater W is quickly evaporated, then expedited to expand and explode, and the piston 2 is raised by said expansion pressure. After the piston 2 reaches the top dead center, a discharge valve 7 is opened to discharge the seawater W and the evaporated gas are exhausted into a discharge tank 9, then the piston 2 descends and reaches the bottom dead center. Then, the discharge valve 7 is closed, and the suction valve 6 is opened, and thus one cycle of the prime mover is completed. |
