摘要： A stem engine has a fluid container, a heating device and a cooling device. The fluid container has an outer pipe having an upper closed end, and an inner pipe provided in the outer pipe and having a fluid inlet port through which the inside of the inner pipe is operatively communicated with the outside of the inner pipe. The inner pipe has a pressure control device at its lower end, and a fluid injection port at its upper end for injecting the working fluid in the inner pipe into a space defined between the inner pipe and the outer pipe, when the pressure in the inner pipe is increased. The working fluid injected into the space between the inner and outer pipes is heated and vaporized by the heating device, so that volumetric expansion of the working fluid takes place to increase fluid pressure in the fluid container. The vaporized steam is then cooled and liquidized by the cooling device and thereby the volumetric contraction takes place, so that the fluid pressure is decreased. By repeating the above volumetric expansion and contraction of the working fluid, the pressure change is given to the working fluid in the fluid container.

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： To improve refrigerating efficiency by preventing working fluid flowing into a pulse tube from a high-temperature end side thereof from reaching a cooling part in a cryogenic refrigerator, a ball-shaped travel member which has almost the same cross-section as the cross section of the pulse tube is inserted into the pulse tube and moves together with the working fluid therein. In this arrangement, when the working fluid begins to flow into the pulse tube from a flow rate regulation part on the high-temperature end side of the pulse tube, the travel member located within the pulse tube moves toward a cooling part together with the working fluid flowing in the pulse tube. Since the travel member has almost the same cross-section as the cross-section of the pulse tube, there is no possibility that the working fluid flows through between the inner wall of the pulse tube and the travel member. Therefore, the travel member can reliably prevent the working fluid flowing into the high-temperature end of the pulse tube from reaching the cooling part, and thereby the refrigerating efficiency of the pulse tube refrigerator can be improved.
