Abstract
A heat engine. A plurality of body members each having a pressure chamber and a cooling chamber. A valve is mounted in each body member and adapted to connect and disconnect the pressure chamber and cooling chamber. A heat source is mounted in the pressure chamber and a ratchet operated pinion gear is connected to the pressure chamber. A not quite circular cam is mounted to operate the valves. The plurality of body members are mounted inside the cam to rotate about the center point of the cam whereby the pinion gears of the body members are connected to rotate a power output gear when the valve for each body member is in closed, heated position, and the pinion gear in each body member are disconnected from the power output gear when the valve in each body member is in open, cooling position. The heat source may be a radio-isotopic heat element.
