摘要： A pliable hinged nonbuoyant flapper valve having a frusto conical projection for centering the valve in relation to a toilet drain, and for permitting the flapper valve to contact a toilet drain valve along a continuous line of engagement of seal the toilet valve. A chain connects the flapper valve to a toilet control lever. A ball float having a positive buoyancy slightly greater than the mass of the flapper valve is interposed an an adjusted location between the lever and the flapper valve for holding the flapper valve in an opened position to allow a predetermined volume of water to flow through the toilet drain.

摘要： A water saver unit to be immersed in an filled with the water of a water-flush toilet system, the unit comprising a hollow body having a pair of clearance holes disposed diametrically opposite one another; a slot formed in the body and connected to and extending between said clearance holes, the slot and clearance holes providing communication between the outside and inside of the body to permit the body to be filled with water. The body being formed of flexible material so that pressure applied adjacent each said clearance hole and respectively directed toward the center of the body caused the body to distort, which distortion cause the slot to increase in width and so that when said pressure is relieved, the body will return to the non-distorted condition wherein the width of the slot is the same as before said distortion; and a weight inside of said body and being in the form of an annular member, having a central clearance aperture and a slot extending from the aperture to the periphery of the member.

摘要： Apparatus is provided for installation in the water tank of a toilet to reduce the quantity of water discharged from the tank during flushing while maintaining a satisfactory flushing action. The apparatus comprises a pair of flat, flexible partition elements which extend in a bowed manner between the front and rear walls of the tank on opposite sides of the tank-drain. A bead of deformable gasket material extends along the side and bottom edges of each partition, and the bead is urged into frictional engagement with the walls by the tendency of the partition to straighten from its bowed position. The partition elements form pockets on each side of the drain for containing water near the bottom of the tank while permitting water above the drain and the pockets to flow down the drain when the toilet is flushed.
摘要翻译：提供装置用于安装在马桶的水箱中，以减少在冲洗期间从罐排出的水量，同时保持令人满意的冲洗作用。该装置包括一对平坦的，柔性的分隔元件，其以鞠躬的方式在罐排放管的相对侧上在罐的前壁和后壁之间延伸。可变形衬垫材料的胎圈沿着每个隔板的侧边缘和底部边缘延伸，并且通过分隔件从其弯曲位置伸直的倾向，使胎圈被迫与壁摩擦接合。分隔元件在排水口的每一侧形成凹槽，用于在罐的底部附近容纳水，同时允许排水口上方的水，并且当厕所冲洗时，口袋向下流出排水口。

摘要： The amount of water used in evacuating the bowl of a water closet is substantially reduced by an auxiliary device that is installed in the conventional closet water tank and which forms an open ended column around the valve so that water stored in the base of the tank and around the column is prevented from being discharged during flushing.

摘要： A flush toilet has a reservoir tank, a toilet main unit, a water supply apparatus, a water discharge apparatus, and a control device for controlling flushing of the bowl portion of the toilet main unit; wherein this control device includes a time measurement device for measuring the time after the water discharge apparatus has been driven for a predetermined time to discharge flush water, until the water level rises from a dead water level inside the reservoir tank with the water discharge apparatus in an off state to a predetermined stopped water level prior to start of flush; and the driving time of the water discharge apparatus responsive to pressure losses in the toilet main unit is adjusted by comparing the water level rise time measured by the time measurement device with the water level rise time in a standard toilet.

摘要： A dual-drainage switching mechanism of water tank has: a water container with bottom opening of the inner cavity, an air vent communicating with the inner cavity is arranged on the sealed top; a valve unit used for controlling opens or closes of the air vent; a drain valve controller comprising a partial flush button and a full flush button, and the air vent is opened through the linking and coupling of the full flush button and the valve unit, and the air vent is closed through the linking and coupling of the partial flush button and the valve unit. The dual-draining switch is achieved through hermetically storing or non-hermetically controlling part of water body in the inner cavity of the water container, traditional one-pressing drain valve can be transformed into the draining control mechanism with dual-draining function.
