ABSTRACT:
The invention is a solar-powered, Rankine cycle, two fluid engine useable for many functions, especially for pumping liquids from the ground such as water or oil in remote locations. The engine driven by heat energy collected in standard collectors or in solar ponds utilizes a heated fluid such as water to transfer the heat from the collectors to a tank where a volatile working medium is transformed into a pressurized vapor. The heated working medium is then fed to a double acting cylinder where work is extracted from the working medium. The engine's valving is controlled by electric switches. The storage batteries are continuously charged by solar energy. If the source of energy is heat collected by standard collectors, a tracking device for the collectors, also driven by solar power, is incorporated in order to attain high collection efficiencies. The engine is used to drive either mechanical or hydraulic pumping devices. The invention is especially suited to remote locations, and for those purposes where constant vigil of the engine is impractical. The engine and the accessories are self-sufficient in that they require little or no maintenance, and are not dependent on a fuel or electricity supply.
