Abstract
The present invention comprises a venturi- and snorkel-less water fountain nozzle that creates low mounds of flowing water for water fountain displays. Instead of incorporating a venturi and snorkel like prior art nozzles, the present invention features an inverted cone dispersion element mounted partially within the nozzle that accelerates water flowing through the nozzle and directs it radially outwards to produce the appearance of a mound. The nozzle is typically submerged under 1/2 to 3/4 inches of water. The appearance of the mound can be varied by varying the depth of submergence of, or the flow rate of water through the nozzle.
