ABSTRACT:
A solar engine including an air motor driven by a quantity of pressurized hot air from a solar heater vessel and including an air pump for pumping substantially an equal mass of cool air back into the solar heater. The driving action of the air motor and simultaneous pumping action of the pump is accomplished in one embodiment by means of a moving piston which separates the driving and pumping sides of the air motor enclosure, whereby substantially both displaced volumes are substantially equal. Air is used as both the heat transfer means and as the actual working fluid. The engine provides for an unlimited life for the solar collector, and an engine of relatively low friction and substantial simplicity.
