ABSTRACT:
The invention disclosed herein relates to an improved method and apparatus for extracting useful energy from the superheated vapor of a working fluid by a vapor actuated power generating device. The apparatus utilized includes a high pressure vessel which receives a superheated vapor and contains one or more positive displacement piston and cylinder assemblies connected to a rotational output shaft with the top face of each piston directly connected to a larger piston and cylinder assembly which operates at lower pressure and is contained within one of the low pressure sections of the apparatus which also serves as the condenser. The low pressure piston is axially connected to an injector piston and cylinder assembly also located within the same low pressure section which transfers liquefied working fluid to heat absorption cells for acquiring sufficient heat to vaporize and superheat the working fluid for recycling.
