Abstract

To provide a cannon (1) of optimum efficiency, which is able to produce an artificial snow of various characteristics and also as close as possible to those of natural snow, and is quieter than current cannons for equal nozzles installed, use is made of water atomization nozzles (8) provided with a sized capillary hole (11) having lobes (12) positioned on opposite sides of the central axis of symmetry (9) of the nozzle (8), (Figure 5). <IMAGE>
