    • A flushing cistern to produce an energetic flush with a reduce volume of water, some 5 or 6 liters for low-level use. The cistern has a housing supporting a rotatable water holder having a large flow aperture in a curved surface and otherwise closely conforming to the inside of the housing. The flush outlet is a large tapering outlet of hydraulically-efficient form to which the aperture matches when the holder is rotated to produce a flush. The filling of the water holder can be arranged to occur only when the holder is in the correct position. Fault conditions are indicated by a warning flow of water from an overflow or elsewhere.
    • 一个冲洗水箱,以减少水量产生精力充沛的冲水,约5或6升用于低水平使用。 水箱具有壳体,该壳体支撑在弯曲表面中具有大的流动孔的可旋转的水保持器,并且以其它方式紧密地符合壳体的内部。 冲洗出口是当保持器旋转以产生冲洗时孔径匹配的大型锥形出口的液压效率形式。 水保持器的填充可以仅在保持器处于正确位置时进行。 故障状况由溢流或其他地方的水的警告流量表示。
