  • the object of the invention is therefore to provide a spray device for irrigation systems of the aforementioned type, by means of which it is easily possible, despite the Rotational movement of the spray nozzle to produce a rectangular spray pattern, so that even rectangular areas are irrigated. Furthermore, the aim is to ensure that the area to be irrigated is sprayed with water everywhere in an extremely uniform manner. The construction effort required for this should be kept low, nevertheless a satisfactory working method should be guaranteed and an easy installation should be given. Furthermore, existing spraying systems should also be easy to equip without difficulty.
  • the spray nozzle is preceded by an allocation device by means of which the amount of the spray medium to be supplied in each case can be regulated depending on the position of the spray nozzle.
  • the metering device is to be formed from two control disks which can be rotated relative to one another and are arranged in a planar or spherical manner and into which control openings which are assigned to one another are incorporated in order to change the amount of spray medium through which flow can occur.

In the corner areas of such a spray pattern, a larger amount of spray medium is supplied to the spray nozzle, so that a protruding liquid jet is generated and the corner is sprayed out.
  • the control of the spray medium to be supplied to the spray nozzle can be controlled with the help of the control disks without difficulty in such a way that a straight-line limitation of the sprayed field can be achieved.
  • the spraying device is equipped with a device for periodically regulating the speed of rotation of the spray nozzle. This device thus ensures with certainty that the field to be sprayed is applied uniformly everywhere, despite the larger area in the corner regions of a rectangular field, with the medium to be sprayed.
