    • A flush valve for use in a flush tank for control by the operator of the amount used in flushing, the valve including an elongate body having a solid generally hemispherical protuberance extending outwardly on one side and a hollow frusto-conical cup member extending outwardly from the other side. A tab and opening therethrough on the forward portion of the body for connection to the valve operating system allows the valve to be alternatively turned with the cup member facing upward and being non-buoyant or having the cup member facing downwardly whereby air trapped therein renders the valve buoyant for substantially a full flush. Spaced arm members extend laterally from the rearward portion of the valve body and have one or more openings pivotally mounting the valve to the normal overflow tube to position the valve with respect to the water outlet in either selected position.
    • 一种用于冲洗水箱的冲洗阀,用于操作者用于冲洗的量控制,该阀包括一个细长体,该细长体具有在一侧向外延伸的实心大致半球状的突起,以及从该侧向外延伸的中空的截头圆锥形杯构件 另一边。 在主体的前部与阀操作系统连接的突片和开口允许阀可选地转动,其中杯构件面向上并且是非浮力的或者使杯体面向下,从而使空气被捕获在其中 阀浮力基本上完全冲洗。 间隔的臂构件从阀体的后部横向延伸并且具有一个或多个开口可枢转地将阀安装到正常溢流管,以将阀相对于出水口定位在任一选定位置。

    • A dual flush valve assembly for a toilet tank including an overflow pipe, a pair of spaced inlets communicating with the pipe, a pair of flap valves selectively closing the inlets, a pair of spaced handles connected to respective valve operating rods controlling the flap valves, a fitting disposed in an opening in a front of a tank mounting the handles thereto in substantially the same vertical plane one above the other, and two spaced pairs of shoulders extending outwardly from the fitting with the handles being movable between a respective spaced pair of shoulders to limit the movement thereof. The flap valves have a wedge shaped body and are reversible for increased life thereof. The pipe and pair of inlets are removably mounted to a drain extending within the tank from the toilet basin without removal of the drain pipe. The overflow pipe may be aligned with the drain pipe with the inlets being offset therefrom, or one drain pipe and full flush inlet may be offset with the partial flush inlet being aligned with the drain pipe.
    • 一种用于马桶水箱的双冲洗阀组件,包括溢流管,与管连通的一对间隔开的入口,一对选择性地关闭入口的活门阀,连接到控制活瓣阀的相应阀操作杆的一对隔开的手柄, 一个配置在一个开口中,一个安装手柄的开口中的一个开口,该手柄在大体上相同的垂直平面上相互垂直放置,并且两个间隔开的一对肩部从配件向外伸出,手柄可在相应间隔开的肩部之间移动 以限制其运动。 瓣阀具有楔形体,并且是可逆的以增加其寿命。 管道和一对入口可移除地安装到从马桶盆内延伸到罐内的排水口,而不需排除排水管。 溢流管可以与排水管对准,其中入口从其排出,或者一个排水管和全冲洗入口可以偏移,而部分冲洗入口与排水管对齐。
