    • Injection apparatus is provided for injecting a drive fluid, such as liquefied nitrogen, into the working chamber (50) of a cryogenic engine. Liquefied nitrogen is admitted to a housing (36) of the apparatus under the control of an inlet valve (42) and expelled from the housing (36) under the control of an outlet valve (48). In the housing (36), heat is transferred to the liquid nitrogen to cause a small volume of the liquefied nitrogen to boil and thereby inject the drive fluid into the cryogenic engine under pressure. In each of two embodiments (Figures 1 to 7) the liquid nitrogen is transferred to a warmed region of the housing by a moveable injection member (4, 20) and in two further embodiments the housing is formed as a heat exchanger through which the nitrogen passes.
    • 提供注入装置用于将驱动流体例如液化氮注入低温发动机的工作室(50)。 液化氮在入口阀(42)的控制下进入设备的壳体(36),并在出口阀(48)的控制下从壳体(36)排出。 在外壳(36)中,热量被传递到液氮中,使得少量液化氮气沸腾,从而在压力下将驱动流体注入低温发动机。 在两个实施例(图1至7)中的每一个中,通过可移动注射构件(4,20)将液氮转移到壳体的加热区域,并且在另外两个实施例中,壳体形成为热交换器, 经过。
