摘要： A thermally powered engine has a pair of power cylinders with each power cylinder defining a closed interior space. A power pistin is reciprocally mounted in the interior space of each power cylinder with each piston dividing the interior of its cylinder into upper and lower portions. A liquid piston interconnects the upper portions of the two power cylinders. First mechanically powered valves having two states control the flow of the working fluid of a heat transfer loop through the lower portions of each power cylinder. A second mechanically powered valve causes the first mechanically powered valve to change state so that movement of the power pistons in the pair of power cylinders is substantially 180.degree. out of phase.
