ABSTRACT:
A tap for the delivery of water in sanitary, domestic, public and industrial plants is equipped with one or more than one shutters of truncated-cone or flat spiral shape, controlled by a push-button. The push-button consists of a small strip of elastic metallic material coated with rubber or plastic material. The turn with the smallest diameter of each shutter is fastened to the end of its control shaft. The turn with the widest diameter can be fixed around the housing of the shutter bore or be movable with respect to the same. Each shutter may also be opened only in part to have the tap deliver water at a variable rate of flow or it may be locked in the open position by a locking and release device to have the tap deliver water at a constant rate of flow. To each shutter corresponds a different rate of water flow when completely opened, the rate of flow being indicated with reference marks on the push-button. By combination of two taps having more than one shutter, a hot and cold water mixing tap is obtained.
