Definitions

  • the invention relates to a sprinkler, in particular a pop-up sprinkler.
  • nozzle body emitting the water jet within a Sets of several nozzle bodies changeable, for example, depending on the size of a variable adjustable angle sector of irrigation to choose a best adapted to the selected sector size nozzle body as the water jet emitting active nozzle body.
  • a change of the nozzle body can, for. B.
  • the invention has for its object to improve the possibility of correct nozzle selection in such a sprinkler, and / or to avoid inappropriate irrigation by an incorrect labeling.
  • the fixed assignment of a distinguishable marking to each of the several different nozzles and their recognizability when looking at the lid of the sprinkler head allows the user to quickly understand which of the nozzles is in the position determined in the sprinkler head for discharging a jet of water, thereby also making it easy to judge it is possible whether the active nozzle body is tuned sufficiently well to the current irrigation task or a nozzle change would have to be made.
  • the fixed assignment which can be arranged on a respective uniquely coupled auxiliary element both by the preferred arrangement of the marking on the respective nozzle body itself or, in particular with rotatable multi-nozzle carrier, avoids accidental false labeling, as in the case of only loose assignment of a separate handle from the nozzle bodies identification element , as the type plug mentioned above may occur.
  • the marking can be given both alphanumerically and by symbols.
  • the label may also have markings on the top facing lid surface, which may also be given alphanumeric or by symbols, work together.
  • a window is provided in the upward-facing cover plate of the lid in a preferred embodiment.
  • the window can both have a through-passage through the cover plate and be covered by a transparent pane.
