Abstract
Abstract An apparatus and method for converting heat energy to mechanical energy in a closed circuit power unit by alternately expanding and vaporizing and then condensing a working fluid to product a pressure differential utilized to operate a reciprocal engine component such as a piston or diaphragm. The apparatus includes an improved and simplified engine component efficiently operated by the pressure differential resulting from the heating and cooling of the working fluid and also includes a series of nonsimultaneously operating combination fluid heat generators and condensors to maintain a continuously available source of heat and cooling for acting on the working fluid. This invention is illustrated in association with a motor vehicle air conditioning system where the heated fluid in the normal engine cooling system is utilized to provide heat to the working fluid heat generators in a controlled sequence whereby the heat energy created is utilized to operate the engine component which in turn is coupled to the compressor unit of the air conditioning system or which may otherwise be connected to any other appropriate work load. This new engine is also operable by any other suitable source of heat.
