Definitions

  • the invention relates to a snow gun with a fan tube, which is traversed by air and at the end of nozzles for introducing water and compressed air are arranged in the exiting spray, wherein the nozzle valves are connected upstream.
  • the invention has set itself the goal of creating a snow gun, the valves are smaller and cheaper.
  • valves are controlled by compressed air, to which pilot valves are arranged.
  • the advantage of the invention is in particular that small pilot valves control large working valves, wherein the pilot valves can be arranged in a heated cabinet.
  • the invention is described in more detail below with reference to an embodiment shown in the drawing, without being limited to this example.
  • the single figure shows schematically a snow gun according to the invention.
  • the fan tube 1 of a snow gun in the direction of arrow 2 is traversed by air.
  • This air is generated by a fan arranged at the other end of the fan tube 1.
  • nozzles 3 are arranged to bring water and compressed air in the exiting spray.
  • valves 4 are connected upstream. These valves 4 water is supplied via the line 5 and compressed air via line 6.
  • the valves 4 are controlled by pilot valves 7. These pilot valves 7 are supplied with compressed air via the line 8.
  • the valves 4 are controlled by the pilot valves 7 via compressed air lines 9.
  • the pilot valves 7 may be arranged in a heated cabinet and are much smaller than the valves 4.
  • pilot valves 7 are shown near the valves 4, but this is only chosen to illustrate the invention, in fact, the pilot valves 7 will be further away from the valves 4.

Abstract

L'invention concerne un canon à neige doté d'une conduite d'air (1), qui est traversée par de l'air. A l'extrémité de la conduite sont disposées des buses (3) introduisant de l'eau et de l'air comprimé dans le jet de pulvérisation sortant, des vannes (4) étant montées en amont des buses (3). Les vannes (4) sont commandées par air comprimé, des vannes pilotes (7) étant par conséquent montées.
