摘要: The cryogenic pump operates in two stages, utilizing a supercharging part and a high pressure part. These two parts are comprised of a high pressure piston pump (3, 4, 34, 35) and a supercharger (5, 6, 61, 62) disposed in a tandem relationship and sharing a common piston rod (8). The supercharger is enclosed in a heat insulated intermediate container (7) and delivers the liquid cryogenic fluid to the high pressure cylinder. The pump operates to convey a liquid cryogenic fluid such as liquid nitrogen, for example, at a high pressure through evaporating means into pressure resistant commercial steel cylinders where the gaseous nitrogen is kept at a pressure of 200 bar and ambient temperature.

摘要: The device operates with an internal combustion engine (1) and utilizes the combustion heat of the same. In addition to the heat of the cooling water exiting from the engine (1), the exhaust gases are transferred to a water circuit in an exhaust gas heat exchanger (4). The mechanical performance of the engine (1) is, through the direct application of a hydraulic brake (14), almost completely changed into thermal energy, and the heat thus produced is likewise conducted to the water circuit. The water heated is conducted through a vaporizing unit (7), where it brings the cryogenic fluid conducted in a pipe coil (25) or in a pipe assembly to vaporization.
摘要翻译: 该装置与内燃机(1)一起工作,并利用其内燃机的热量。 除了从发动机(1)排出的冷却水的热量之外,废气也被传送到排气热交换器(4)中的水回路。 发动机(1)的机械性能通过直接施加液压制动器(14)几乎完全变成热能,并且由此产生的热量同样被传导到水回路。 加热的水通过蒸发单元(7)进行,其中将导管在管线圈(25)或管道组件中的低温流体带入蒸发。
