Abstract: A snow making nozzle in which streams of water impinge on each other to atomize the water and to direct the water out of the nozzle with the assistance of compressed air to spray the atomized water into the atmosphere to make snow is disclosed. The nozzle uses opposed groups of water outlet ports carried in nozzle plates. These water outlet ports are angled toward the outlet of the nozzle and are located at the venturi of a converging-diverging nozzle with each water outlet port in the upper plate being directly opposite from a corresponding water outlet port in the lower plate so that the water streams from cooperating ports directly contact each other. Impingement of these streams with each other provides superior water atomization which takes place without contacting the body of the nozzle. The inclination of the water outlet ports increases the operating efficiency of the snow making nozzle and allows more snow production per unit of energy than prior art devices.

Abstract: A snow-making nozzle assembly which is very effective in producing uniform, small, highly atomized droplets of liquid that freeze to form snow is disclosed. The nozzle assembly in accordance with the present invention is comprised generally of opposed pairs of water outlets spaced at the periphery of a generally fan-shaped convergent-divergent compressed air nozzle. The water streams emitted from the water outputs impinge on each other and atomize substantially without contacting the walls of the nozzle. These liquid particles are entrained in the compressed air stream for further atomization and for distribution into the ambient air. The use of the nozzle in accordance with the present invention results in greatly improved snow-making capabilities when compared with prior art devices.
