    • A flushing device for toilets having a float directly connected to the movable part of an inlet valve to form a unitary moving element. A siphon empties the flush tank and becomes inactive until a full tank is flushed again. When the float, which is slidably mounted in a chamber, is forced down for flushing, it forces water from the float chamber into the siphon either alone or with water from the inlet valve, to start a siphoning action to empty the flush tank. At the same time the float opens the inlet valve to supply additional water to start the siphon and to keep the valve open until the flush tank is refilled at which time the float has been raised to its normal position. Provisions are made for preventing a reverse flow from the tank into the inlet pipe during failure of the water supply and for filling the toilet bowl to the desired level at the end of the flushing operation. Provision is also made for conserving water by flushing a predetermined quantity of water for solids and considerably less water for liquids and by providing means for regulating the amount of water to be flushed by the flushing unit.
    • 一种用于厕所的冲洗装置,其具有直接连接到入口阀的可移动部分的浮子,以形成一体的移动元件。 虹吸管清空冲洗水箱,变成无效状态,直到满罐再次冲洗干净。 当可滑动地安装在腔室中的浮子被迫下压以冲洗时,其将来自浮子室的水单独地或与来自入口阀的水一起推入虹吸中,以开始虹吸作用以清空冲洗罐。 同时,浮子打开入口阀,以提供额外的水来启动虹吸管并保持阀门打开,直到冲洗槽被重新填充,此时浮子已升至其正常位置。 规定了防止在供水失败期间从罐进入入口管的过程,并且在冲洗操作结束时将马桶盖填充到所需水平。 还规定了通过冲洗预定量的用于固体的水和相当少的用于液体的水并通过提供用于调节冲洗单元冲洗的水量的装置来节约用水。
