  • Patent number: 4145000
    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.
