Abstract:
A snow gun (40) having a tubular housing (41), outlet (43) for cold compressed air (42) and outlet (44) for water (49) discharged under pressure, said outlet for water consisting of nozzles (44) disposed along a ring-shaped cross-sectional area of the housing, each nozzle forming an angle relative to an internal wall (41b) of the housing, and said nozzles (44) being located downstream in relation to the compressed air outlet (43) where the compressed air expands, characterized in that said nozzles are located upstream in relation to an outlet aperture (45) of the housing, and that both are outlet (43) for compressed air (42) and the water nozzles (44) are thus surrounded by the tubular housing (41) between an inlet end (41a) and the outlet aperture (45) of the housing, and that water jets from the nozzles (44), where they meet upstream in relation to the outlet aperture (45) of the housing, form a configuration having approximately the shape of a polygon or circle (47), there being a fan (50) downstream in relation to the inlet end (41a) of the housing (41), said fan (50) being located coaxial with the housing (41) axis and being operated by the pressurised water which in addition is fed to the water nozzles (44).
