The nozzle comprises an internal chamber (8) supplied with pressurized fluid which communicates with an annular discharge orifice (5). It comprises an internal channel (2) centered on the annular orifice axis and whose diameter corresponds substantially to the diameter of said annular orifice, said channel providing for a double flow around the nozzle and the fluid film coming out of the orifice. The nozzle may be used to spray all types of fluids: water, fuel, in applications involving high flow rates in the order of 5 to 60m<3>/h, yet in very fine droplets. The spraying device fitted with such nozzle comprises preferably two contrarotary fans (22 and 23). The nozzle (1) may also be provided with nucleators (70) arranged on its periphery so as to provide seeding of the water/air mixture for the production of artificial snow. The disclosed spraying device has the advantage of being particularly compact. |
