摘要： An external combustion engine including a container 10 sealed with a working medium 14 in liquid phase adapted to flow, a multiplicity of evaporators 201 to 204 for heating and evaporating part of the liquid-phase working medium 14, a multiplicity of condensers 221 to 224 for cooling and condensing the working medium 14 evaporated in the evaporators 201 to 204, and an output unit 11 for outputting by converting the displacement of the liquid-phase portion of the working medium 14 into mechanical energy. The multiplicity of the evaporators 201 to 204 share a heat source from which heat is supplied thereto. The engine further includes an influent liquid amount regulation unit whereby the liquid-phase portion of the working medium 14 in a greater amount flows into the evaporators nearer the heat source upon displacement of the liquid-phase portion of the working medium 14 toward the multiplicity of the evaporators 201 to 204 from the output unit 11, while the influent liquid amount is smaller for the evaporators farther from the heat source. In this way, heat loss is reduced resulting in improved efficiency.

摘要： In a steam engine having a heating device, a cooling device, and an output device, the output device comprises a piston reciprocally moving by a self-excited fluid vibration of a working fluid in a fluid container. The piston is reciprocally moved by the output device for a certain period before starting an operation of the steam engine, so that the working fluid is moved to an inside space of the heating device. Since the working fluid is surely heated and vaporized by the heating device, the fluid vibration is stably started, and as a result, the operation of the steam engine can be smoothly started.

摘要： A liquid pump for circulating working fluid (water) in a Rankine cycle comprises a U-shaped fluid vessel having a bending pipe portion and a pair of straight pipe portions, wherein a heating device and a cooling device are provided at one of the straight pipe portions for heating and cooling the water in the fluid vessel. The liquid pump further has a discharge pipe portion and an inlet pipe portion, and check valves are respectively provided in the discharge and inlet pipe portions. The water is vaporized by a heating operation of the heating device to increase pressure of the working fluid in the pump, so that the working fluid is discharged. The vaporized working fluid is then cooled down by the cooling device to decrease the pressure of the working fluid in the pump, so that the working fluid is sucked into the pump.

摘要： A steam engine has a fluid container, a heating device and a cooling device provided at the fluid container for heating and cooling working fluid filled in the fluid container, so that a part of the working fluid is heated and vaporized to move the liquid-phase working fluid in one direction. When the vaporized steam is cooled and liquidized, the pressure of the working fluid in the fluid container is decreased, to thereby move the liquid-phase working fluid in the backward direction. Kinetic energy is thereby generated by using the back and forth movement of the working fluid. The heating device has multiple through-holes, through which the working fluid flows and heated by a heating surface (an inner surface of the through-holes) of the heating device, wherein a diameter “d” of the through-hole is made almost equal to or smaller than a depth of heat penetration “δ”, which is determined by the following formula: δ=√{square root over (2a/ω)} wherein “a” is a heat diffusivity of the working fluid, and “ω” is an angular frequency of the working fluid during the working fluid is periodically moved back and forth.
