Abstract: An electronically operated mixing valve is disclosed wherein a combination of a control module which houses the electronics for electrically operating a valve module having one or more valves for mixing, shut-off and distribution of mixed water which is in contact with at least one temperature sensor, and an electromechanical motor module which is electrically connected to the valve module for automatically operating the one or more valves.
Abstract: A self-closing valve, having means to discharge a predetermined volume of water for each cycle of operation, is disclosed. The valve includes the arrangement of timing means which determines the elapsed time for its operational cycle, a one-way valve means to expel air from the metering chamber during the actuating cycle of the valve, and air metering means which replaces air entering the mixing chamber at a constant uniform rate, all of which cooperate with the valving means to discharge a predetermined volume of water.

Abstract: The invention relates to a sanitary single-handle mixing valve having control elements composed of at least two discs, one of which serves as a fixed valve seat disc with two inlet openings for cold and hot water. For purposes of operating the mixing valve in combination with thermally or hydraulically controlled flow heaters, the centroids of the port areas of the inlet openings, or at least the centroid of the port area of the cold water inlet opening, is shifted a few degrees of angle towards the cold water setting in order to achieve hydraulic asymmetry when the operating handle is in its central position.
Abstract: The invention relates to a combination single-handle mixing valve and appliance valve assembly, mounted in a common housing and having common hot and cold water connections. The appliance valve, axially positioned between the mixing valve cartridge and the manifold, is in fluid communication with the mixing valve and includes a handle to supply water to the appliance.
Abstract: A self-closing valve assembly for sanitary installations is disclosed. The valve assembly includes upper and lower valve housings which define a metering chamber that is normally filled with a metering fluid. A metering means, shiftably mounted in the lower valve housing, includes a first one-way valve means which displaces a predetermined volume of the metering fluid when said valve assembly is shifted to its opened position. A closure means, which includes a second one-way valve means, is operably coupled to the metering means to automatically shift said metering means from its opened to its normally closed position, by transferring the displaced volume of said metering fluid in the metering chamber through a second one-way valve means after a predetermined period of time has elapsed, to thereby close said valve assembly.
Abstract: An illustrative embodiment of the invention provides a peripheral flange generally perpendicular to the plane of the lavatory basin. The flange has a generally downwardly, inwardly sloping surface to enable the splash water to flow into the basin within the lavatory. As the flange sweeps around the periphery of the lavatory it develops into a massive spout support. The spout support enables the spout to direct water into the basin without causing the spout to extend across the basin surface. The support also has a protruding portion that establishes a reentrant basin surface in which the overflow drain is concealed from view when the lavatory is installed.
