Abstract
1. Snow gun having a central compressed-air supply line (1) and a pressurized-water supply line surrounding the latter and disposed coaxially therewith, the compressed-air supply line opening out into an interior space of a spray-head (7) at the front, in the direction of the compressed air supply, the space being bounded by a bored endpiece (8) and serving as a preexpansion chamber (9), inner nozzles (4) in the form of bores passing through the outside wall of the compressed-air supply line (1) being provided between the compressed-air supply line (1) and the pressurized-water supply line, through which nozzles the compressed air issues into the pre-expansion chamber (9) and mixes with the pressurized-water, characterized in that the compressed-air supply line (1) has three identical inner nozzles (4), and the endpiece has three centrosymmetrically disposed discharge nozzles (10) of identical diameter, none of which is situated in the geometric axis of the compressed-air supply line (1), and the diameter of a discharge nozzle (10) corresponds to 1 to 3 times the diameter of an inner nozzle (4).
