Abstract (en)

[origin: EP2071258A1] The nozzle (20) has a nozzle channel (25) with a compressed air inflow opening (24), where cross-section of the channel in a section is reduced in a direction of an outflow opening (23) of the channel up to a smaller diameter. The cross-section of the channel in another section (27) expands in the direction of the outflow opening. A water inflow opening (22) temporally opens out into the channel, where a ratio of cross-sectional surfaces of the outflow opening to cross-sectional surfaces of the channel in a region of the smaller diameter amounts to 4:1 preferably 9:1. Independent claims are also included for the following: (1) a snow blower comprising a nucleator nozzle (2) a method for producing artificial snow.
