  • the water jets emerging from the nozzles impinge on the inside of the deflector hood, spread there and run down over the surface of the inside to the lower edge of the deflector hood. Most of the water then drips down from the lower edge of the deflector hood.
  • the deflector hood already has a certain inner diameter in order to be able to cover the pipe to be supplied with water, the lower edges of the deflector hood are at a distance from one another, which can already correspond approximately to the thickness of an air-permeable element.
  • the dripping water then impinges on the outer edges of the air-permeable element, when the water pipe and the deflector hood are aligned with each other.

  • a channel is formed at the top of the air-permeable element whose side walls project beyond the channel bottom by a distance measure, the channel bottom and / or side walls to the air-permeable element are water-permeable, and formed on the water pipe nozzles or the deflector plates associated with the nozzles are aligned with the channel.

  • the water-permeable bottom and / or the side walls of the channel the water enters from the channel down into the central vertical inner layer and thus into the inner core of the air-permeable element and can go through in this area down to.
  • the air-permeable element in its inner core much better and more evenly supplied with water. From the inner core, the water seeping down can and should reach the area of the outer surfaces of the air-permeable element.

  • the material of the distributor element may have finer structures than the material of the air-permeable element, so that it sucks well with water and achieved over a uniform distribution of water.
  • the distributor element thereby causes a homogenization of the water supply over the contact surface and over time.

  • the nozzles may be arranged at greater distances from each other and have larger outlet openings, since the discharged water over the channel with a horizontal orientation of the channel again distributed evenly over the working width of the air-permeable element.
