    • A device (20) for improving drainline clearance for use with an ultra low flushing volume toilet (24). The device (20) includes a centrifuge separator means (30), for separating liquids (L) and solids (S), and a reservoir (42). The separator means (30) has a substantially horizontal inlet (32), adapted for connection to the outlet (26) of a toilet pan (24), an outlet (36) primarily for solids (S) and an outlet (38) primarily for liquids (L). The reservoir (42) is beneath the separator means (30) and has an inlet (38) in fluid communication with the liquids outlet (38) of the separator means (30). The reservoir (42) is adapted to syphonically empty substantially all of its contents into a sewerage drainline (22) after at least 2 flushes of the toilet (24). Further, the separator means (30) and the reservoir (42) have a combined vertical dimension less than the maximum height of the toilet pan outlet for installation adjacent the toilet (24) and substantially above the floor level (F) of the toilet (24).
    • 一种用于改善与超低冲洗容量马桶(24)一起使用的排水间隙的装置(20)。 装置(20)包括用于分离液体(L)和固体(S)的离心分离装置(30)和储存器(42)。 分离器装置(30)具有基本上水平的入口(32),其适于连接到马桶(24)的出口(26),主要用于固体(S)的出口(36)和主要用于出口 用于液体(L)。 储存器(42)位于分离器装置(30)下方,并且具有与分离器装置(30)的液体出口(38)流体连通的入口(38)。 储存器(42)适于在至少冲洗马桶(24)之后,将其所有内容物基本上清空到污水排水管(22)内。 此外,分离器装置(30)和储存器(42)具有小于便于马桶(24)安装并大体上在马桶(F)的地板水平面(F)上方的便厕盘出口的最大高度的组合的垂直尺寸 24)。

    • An automatically primed continuously operating siphon system including a tank for collecting a liquid therein, the tank having an upper inlet and a lower outlet communicating with a siphon discharge conduit leading therefrom. The tank inlet and outlet each have associated therewith a float operated valve arranged so that during automatic priming of the system the outlet is opened and the inlet is closed to seal the upper portion of the tank in response to a rise in the level of the liquid in the tank. After the tank is sealed a pressure head is established by introducing a pressurized fluid into the sealed tank to thereby force the liquid through the outlet to establish a siphoning flow therein. As the level of the liquid falls as a result of the siphoning flow, the tank inlet is reopened to allow flow therethrough to the siphon, and the introduction of the pressurized fluid is stopped. The tank outlet will open and close in response to the liquid level in the tank to maintain a supply of water in the siphon discharge conduit and permit periodic siphoning of the liquid as it collects in the tank. In addition, safety features may be included to break any suction that may develop due to rapid siphon flow prior to opening of the inlet valve, to shut off the flow of pressurized fluid when the liquid level in the tank is abnormally high, to vent the tank, and to stop further flow of the liquid to the tank.
    • 一种自动引燃的连续操作的虹吸系统,包括用于在其中收集液体的罐,所述罐具有与从其引出的虹吸排出管道连通的上入口和下出口。 储罐入口和出口每个都具有与其相关联的浮动操作阀,其布置成使得在系统的自动启动期间,出口被打开并且入口被关闭以响应于液体水平的升高而密封罐的上部 在坦克里 在罐被密封之后,通过将加压流体引入密封罐来建立压力头,从而迫使液体通过出口在其中建立虹吸流。 随着虹吸流量的下降,水箱入口被重新打开以允许流过虹吸管,停止加压流体的引入。 储罐出口将响应于罐中的液位而打开和关闭,以保持虹吸排放管道中的水供应,并且允许液体收集在罐中时定期虹吸。 此外,可以包括安全特征以打破在打开入口阀之前由于快速虹吸流可能发展的任何吸力,以在罐中的液位异常高时切断加压流体的流动,以排出 罐,并且停止液体进一步流入罐中。
