    • A scroll-type vacuum pump (10) wherein an expander (40, 50) and a compressor (60, 70) are arranged in series, in two stages, in the same housing (20) and driven by the same shaft (22). The first stage is a scroll-type expander. It is in series with a scroll-type compressor, which is the second stage. The volume of the suction pockets of the second stage, the compressor, is not significantly smaller than the volume of the discharge pockets of the first stage device, the expander. Thus, the amount of heat associated with the re-expansion and compression process is reduced. The two stage pump also includes a double shaft seal mechanism (11, 92) which seals off the suction chamber of the expander from both the ambient and the discharge chamber of the expander. The two stage pump of the invention further includes a labyrinth structure (301-304) at the tip surfaces of the scroll elements to tightly control the axial ( delta ) gap between the tips and bases of the mating scroll elements.
    • 一种涡旋式真空泵,其中膨胀机和压缩机分成两个阶段并列在相同的壳体中并由相同的轴驱动。 第一阶段是滚动式扩展器。 它是与涡旋型压缩机串联,这是第二阶段。 第二级的吸入口压缩机的体积不会明显小于第一级装置(膨胀机)的排放口的体积。 因此,与再膨胀和压缩过程相关联的热量减少。 双级泵还包括双轴密封机构,其将膨胀机的吸入室与膨胀机的环境和排放室密封。 本发明的两级泵还包括在涡旋元件的尖端表面处的迷宫式结构,以紧密地控制配合涡旋件的顶端和底座之间的轴向间隙。
