Abrégé

The invention relates to a snow-making system containing a unit (10) having a water-jet gas compressor (2), in which water (W1) as a driving medium under pressure can be introduced into an intake chamber (7) in the form of a driving jet and into which air (L1) can be drawn. The unit further comprises a separating arrangement (3) for separating the water-air mixture (M) from the water-jet gas compressor in the form of a separating chamber, whereby water (W2) and air (L2) can be fed separately from the separating arrangement to a snow gun (4) to produce artificial snow.

A nucleator nozzle (20) for producing ice nuclei is designed as convergent-divergent nozzle. The nozzle channel (25) has a section (27) that is widening. The ratio of the cross-sectional area of the outlet opening (23) to the cross-sectional area of the nozzle channel (25) in the region of the nucleus diameter (26) is at least approximately 4:1. A snow lance (1) having at least one nucleator nozzle (20) and having at least one water nozzle (30; 30') is designed such that water droplets (32) produced by the water nozzle (30; 30') pass through a droplet path (31; 31') of at least 20 cm until they reach ice nuclei (28) from the nucleator nozzle (20) in a germination zone E.

The device for creating artificial snow has a retaining device (6) for receiving an ice block (1), a shaving tool (2), a feeding and retaining element (3; 11) connected to the shaving tool (2) in order to position the shaving tool (2) opposite of the retaining device (6), and a drive device (9, 10, 11) in order to displace the shaving tool (2) opposite of the retaining device (6). With the aid of the feeding element (3; 11) the shaving tool (2) is displaced to rest against the ice block (1), which is disposed in the retaining device (6). This is achieved such that the shaving tool (2) is finally disposed in the working position opposite of a surface (I1) of the ice block (1), that is that with a relative displacement between the shaving tool (2) and the surface of the ice block (1) small particles (S) are shaved, or grated off the ice block (1). These particles (S) correspond to natural snow flakes with regard to their consistency.
