Definitions

  • the invention relates to a device with which a Fluid such as water e.g. on a vegetation area or the like can be applied as a jet.
  • a Fluid such as water e.g. on a vegetation area or the like can be applied as a jet.
  • the jet After detachment from the sprinkler at the fluid outlet, the jet passes under the fluid pressure bundled or sprayed in a free path to the vegetation area. It rises from the sprinkler or it falls to the area to be irrigated.
  • the sprinkler can with anchored to a sprinkler base upright on the ground will. Then the one provided at its upper end Fluid outlet at a distance above the anchor.
  • the sprinkler base has a supply connection for detachable coupling a fluid line, such as a water hose. About him the liquid is channeled under pressure, those inside the sprinkler from the connector to the outlet leads.
  • the outlet is expediently movable relative to the base, in particular rotatable, and in its movement by the flowing water powered. So with that emerging from it Water a larger area than this the case would be if the outlet were stationary.
  • the outlet can have a variety of radially directed outlets on one rotor rotating constantly in the same direction as one Turbine rotor, be provided so that the water in one Entire sector over 360 ° around or in the opposite smaller subsectors is carried out.
  • the discharge can take place close to the sprinkler itself, so that the same water jet radial to the sprinkler over a proportionate long distance strikes the area to be irrigated.
  • This radial expansion or the smallest distance of the sprinkled area from the sprinkler depends on beam cross sections which is the water jet at the fluid outlet or upstream of it inside the sprinkler. It is useful within the Sprinkler provided a nozzle arrangement. That comes from her Water as a jet so that it has a clear path comes against a guide surface, which it the fluid outlet feeds. This can be through the outlet end of the guide surface be educated.
  • the nozzle arrangement has an axis several neighboring nozzle units distributed the same radial distances on. They each set up a separate beam against separate areas of the guide body and supply therefore only the associated, constant Sub-sector of the vegetation area with water. By closure the associated sub-sector can be the associated nozzle unit to be excluded from the irrigation.
  • the single nozzle unit can be formed by a single or multiple jet nozzles be.
  • the outgoing from the nozzle unit or on the Beam cross sections hitting the guide surface also determine the jet shape at the fluid outlet. Is the nozzle unit through? a single, partially or circularly seen in the direction of flow The opening is formed as closely as possible focused beam, which from the fluid outlet via a long distance is carried out and that until immediately area of the vegetation area close to the sprinkler not watered.
  • the invention has for its object a sprinkling device to create at what disadvantages known Training or the type described are avoided and which in particular enables the generation of a fluid jet, which to irrigate the near field of the sprinkler is suitable or is carried out less far than the described, far-reaching water jet.
  • upstream of the fluid outlet Means are provided to remove from the individual nozzle unit to influence generated beam cross section in that it has a shape deviating from the circular shape and in this deviating shape may hit the guide surface.
  • the nozzle channel advantageously has in axial section at least one non-linear channel flank, which is particularly in the direction of flow from the nozzle axis away.
  • a single jet nozzle is expediently provided, which is not circular in axial view, but elongated limited, e.g. long round, flat oval, elliptical or is lenticular. This can narrow the nozzle laterally Areas and have an expanded area in between, so that the beam cross sections mentioned are generated.
  • Axial view expediently lies the larger cross-sectional extent the nozzle at right angles to the corresponding one Fluid outlet leaving the jet, causing this to correspond widened and therefore not carried out as far or already before leaving the fluid outlet parallel and / or at right angles is fanned out to the irrigation area.
