ABSTRACT:
A vapor driven heat engine utilizing a working medium boiling at less than ambient temperature and atmospheric pressure. A heat source vaporizes the medium in a boiler with the vapor being transferred to an insulated vapor header reciprocating a piston in an insulated cylinder by the operation of a control valve exhausting spent vapor at a lower temperature and pressure to a condenser which in turn transfers condensed vapor to a holding tank periodically discharged into the boiler. Vapor is continuously circulated to and from the boiler through heat coils surrounding the vapor header and cylinder to conserve heat energy and pressure.
