Definitions

  • the invention relates to a sprinkler - in particular a surface, rectangular or square sprinkler sprinkler for gardening.
  • Sprinklers are in German usage as Sprenkler - derived from the English word Sprinkler - which in turn is mainly used in German in the fire fighting.
  • the terms irrigation system, sprinkler system, sprinkler, sprinkler or sprinkler are also used for irrigation preparation or installation.
  • the impulse sprinkler or rocker sprinkler is placed on a tripod for irrigation of larger areas and operated via one or two nozzles; These sprinklers work with a jet of water and a nozzle, with which the water can be distributed in different throw directions on the beds or the lawn.
  • a simplified version of the impulse or oscillating lever sprinkler for correspondingly modest applications is the circular, circular or all-round sprinkler, with two water-powered, rotating, mostly kinked pipe nozzles with water-pressure-dependent operation.
  • Pop sprinklers are special sprinklers that are used to irrigate green areas - especially lawns - commonly known as lawn sprinklers or lawn sprinklers. Pop-up sprinklers are offered in different versions; There are plastic or stainless steel climbers, full or partial circle sprinkler with different nozzles.
  • a gearbox opponent is a ground-fed pop-up sprinkler whose gearbox is supplied with water pressure and rotates;
  • the Revolver lawn sprinkler belongs in this type of construction.
  • Gearbox reactors are usually part of a sprinkler system; They allow the targeted irrigation of certain garden areas.

Since the hydraulic system is exclusively controlled by water pressure and no regulation is provided, oscillating relative movements between lawn sprinkler cylinder and nozzle can not be excluded up to a natural frequency of the system. The design of the hydraulic cylinder and the nozzle are not detailed.
