Abstract: A water tap assembly particularly for kitchen sinks includes two ports for connection to cold and hot water supply lines, and also a third port for connection to a special-water supply line, e.g., for supplying filtered or carbonated water. The assembly further includes a control valve, a spout, and a water discharge head removably carried by the spout at the end of a pull-out water conduit. The control valve selects whether mixed-water or special-water is fed to the water discharge head, and the latter head includes a diverter which selects whether the mixed-water is to be outletted as an aerated stream or as a spray.

Abstract: A water tap particularly for kitchen sinks includes a body member attachable to the kitchen sink and having first and second ports for connection to hot and cold water supply lines, respectively, of the kitchen sink and a third port for connection to a third water supply line; and a handle rotatably mounted about a longitudinal axis with respect to the body member and operatively connected to a valve assembly such that: (a) rotating the handle to a selected position within a first operating region connects the first and second ports to a mixing chamber and controls the proportions of the hot and cold water supplied to the mixing chamber from the respective hot and cold water supply lines for discharge through a spout; and (b) rotating the handle to a selected position within a second operating region connects the third port to the spout for discharging water from the third water supply line.
