Abstract: A dual flush mechanism equipped with a two independent flush valves which are each separately controlled by a separate spring loaded button. The flush valves are at different heights in the toilet tank such that actuation of the upper flush valve, by pressing a first button on top of the tank, will produce a short flush, while pressing of the second button will actuate the lower flush valve to produce a long flush. Pivot rods are pivotably supported on a common axis below the first and second buttons. The upper end of each pivot rod is coupled through a spring to its respective push button on top of the tank. The opposite ends of the pivot rods are coupled respectively through a chain to the upper and lower flush valves. Pressing the first button exerts a downward force through the spring on the first pivot rod to raise the opposite end thereof which in turn raises the upper flush valve. Pushing the second button actuates the second pivot rod in the same manner to raise the lower flush valve.

Abstract: A tap includes a sensor (20) for determining the distance between a user's hands (3) and the tap, a mixing valve (40) regulating the temperature of water fed to delivery port (11) of the tap and a controller (30) for processing the distance values provided by the sensor. The temperature of water delivered differs based on the position of the user's hands relative to the tap.

Abstract: A sanitary water fitting having a bearing ring arranged as a sliding bearing between the fitting body and the bearing sleeve. The bearing ring seals off a circling groove holding sealing rings from the bearing sleeve and is itself sealed off from the bearing sleeve by means of an external seal placed at the bearing ring. In its axial extension it borders a water passage opening which is between a circulating water channel and a swivel spout connection piece. The advantage of this invention is that the water flow in the circulating water channel and towards the swivel spout connection piece is controlled in such a way that the formation of lime deposits in the area of the sealing rings is considerably limited even after a relatively long period of operation, or even prevented completely.

Abstract: A cartridge for sanitary fittings including at least one stationary and one movable valve disk enclosed by a housing. The stationary valve disk is adjacent to a base of the housing and has at least one channel for water intake with a recess on the side of the stationary valve disk facing the base. This recess is coaxial with a passage in the base of the housing and accommodates a sealing ring which is also lodged in the passage. A rim is formed on the surface of the base which faces the stationary valve disk whereby the rim encircles the passage and extends into the recess of the stationary valve disk.

Abstract: A sanitary water valve having control elements consisting of at least two discs. The first disc is arranged immovably and constitutes the valve seat disc and the second disc, which constitutes the control disc, is arranged movably on the first disc and has a surface conduit for deflection functions which can simultaneously be made to overlap the inflow apertures and outflow aperture on the first disc. The second disc includes one or more depressions which substantially reduce the actuation forces required to open the water valve and as a result, operating efficiency is considerably enhanced.

Abstract: A valve device is provided, the base of which includes a lower valve seat of a reflux and aerating valve, which is inserted into a hollow space located above the taps. The hollow space is sealed at the bottom and open at the top and/or side. If the valve device has any sealing flaws, the leaking water is collected, and air flows into the valve device via the hollow space if the pressure in the main water supply drops. If any water seeps out of the valve device due to sealing flaws in the valve, water flows from the lower valve seat to the hollow space of the separator wherein it collects and flows out through the opening in the separator. As a result, leakages in the fittings can be detected easily and quickly.
