Device for producing artificial snow, snow cover facility comprising such a device, and method for the operation of such a device

A culture snow making device, comprising a body including:

• a pressurised water supply duct,
• a pressurised air supply duct,
• at least one spray element for spraying water or a mixture of air and water,
• at least one control valve adjusting the supply of pressurised water and/or pressurised air to said at least one spray element, and
• piloting means intended to pilot said at least one control valve, the piloting means comprising a camshaft driven into rotation about a longitudinal axis thereof by an actuator,
• said at least one control valve cooperating with a cam carried by said camshaft,
• wherein said at least one control valve is placed on said pressurised water supply duct and on said pressurised air supply duct, and includes, over a perimeter part, at least one water chamber intended to be supplied with pressurised water via said pressurised water supply duct, and, at least one air chamber intended to be supplied with pressurised air via said pressurised air supply duct, said at least one control valve comprising a fixed body, generally tubular in shape, delimiting an inner housing accommodating a mobile body, translationally mobile along a translation axis extending perpendicular with respect to said longitudinal axis of said camshaft.
