    • A scroll-type fluid displacement machine includes first (2) and second (6) scroll bodies that rotate synchronously together, their rotation axes being offset from one another. A cylindrical partition wall (4a) is provided to extend axially in the center of the scroll bodies. A space is provided between scroll vanes of the scroll bodies and the cylindrical partition wall. The interior of the cylindrical partition wall is cooled by air ventilation, and a grease-lubricated Oldham coupling (13,14,15) is disposed inside the cylindrical partition wall. Hence, the Oldham coupling that is made of a metal is prevented from wear and deformation thereof over a long time. The displacement machine requires neither a counterweight nor a pin-crank device. The machine may be oil-free in the fluid compression part of the scroll bodies.
    • 涡旋型流体排出机器包括同步旋转的第一(2)和第二(6)涡旋体,它们的旋转轴彼此偏移。 提供圆柱形分隔壁(4a)以在涡卷体的中心轴向延伸。 在涡旋体的涡旋叶片和圆筒形分隔壁之间设有空间。 圆柱形分隔壁的内部通过空气通风进行冷却,并且在圆柱形分隔壁内设置润滑脂润滑的十字联轴节(13,14,15)。 因此,防止由金属制成的十字联轴器长时间地磨损和变形。 排量机既不需要配重也不需要销曲柄装置。 机器在涡卷体的流体压缩部分中可以是无油的。
