HIGH PRESSURE SNOW GUN

摘要

A snow gun for making artificial snow by atomizing a mixture of air and water is disclosed. The snow gun comprises a hollow body, a compressed air supply conduit terminated by an injection nozzle accommodated inside the hollow body and opening at an end into the hollow body. A pressurized water supply conduit opens into a space between the hollow body and the air supply conduit. A mixing chamber for mixing air and water communicates through an inlet port with the interior of the hollow body, the inlet port facing the discharge nozzle of the injection nozzle. The injection nozzle is displaceable longitudinally relative to the inlet port of the mixing chamber for adjusting the water flow passage to the mixing chamber. A needle valve adjusts the cross sectional area of discharge orifice of the air injection nozzle. The mixing chamber comprises the bore of a main nozzle extending in the continuation of the injection nozzle. A divergent nozzle extends from the discharge end of the bore and opens to the surrounding air.
