Abstract: A flushing device has a first pushbutton for triggering a flushing with essentially the total amount of water present in the flushing tank and a second pushbutton for triggering a flushing with part of this amount of water. Both pushbuttons are connected to a valve pipe, which is to be raised during flushing and is mounted in a float housing. A beaker-shaped hollow body, which is raised as an additional weight with the closing element in the case of a partial flushing, is arranged in the flushing tank. The hollow body is raised with the closing element during a complete flushing and during a partial flushing alike. In the case of a complete flushing, the hollow body is opened by an opening such that water contained in the said hollow body flows out at least partially when the closing element with the hollow body is raised.

Abstract: A flush valve mounting permitting adjustment of water flow to the requirements of different types of toilet bowl comprises a housing in which a float container with a float therein is removably emplaced. The lower portion of the housing has window apertures through which water can flow from the flush tank into a drain upon lifting of the pipe which carries the valve plate. A wall extending downwardly from the floor of the float container abuts the interior of the window openings, and this wall itself has through-flow apertures separated by webs formed by the wall. The openings in the window apertures are diminished by rotating the float container relative to the housing. This permits the water flow to be adjusted to the requirements of the particular toilet bowl.

Abstract: A regulatable flush valve for tank type flush toilets includes a piston-cylinder dash pot, a weighted (fluid filled) plug/valve, a cylindrical overflow tube and a fluid vortex generating element secured in a coaxial arrangement vertically above the outlet of the toilet tank. The piston and plug/valve secured to the overflow tube are lifted from a normally closed position by a conventional pivoting handle mechanism. The piston-cylinder dash pot determines the water volume of a particular flush by controlling the rate of descent of the weighted plug/valve. The vortex generating element works in combination with the walls of the raised plug/valve to generate an energetic fluid vortex as the water flows from the tank into the toilet bowl. The vortex generated by the generating element is complementary to vortex generating elements within the toilet basin to increase washing action in the toilet bowl. The above combination of elements significantly reduces the volume of water required for complete flushing action.
