  • the foaming device 1 can be rinsed with water and, in particular, can also be used only for dispensing pure water or another cleaning liquid, for example as a conventional dispensing or high-pressure nozzle. In this case, preferably no foaming takes place. If necessary, the air supply, which is otherwise required for foaming, can then be blocked by the valve device 7.
  • the valve device 7 preferably has a rotary handle 8 which surrounds in particular the foam output and / or the foam device I and / or is arranged coaxially therewith for controlling the valve device 7 or chemical admixing. This allows a simple, intuitive operation.
  • the valve device 7 preferably has a particular bolt-shaped adjusting element 9, which is preferably provided with different cross-sectional passage openings, in particular holes 10, for the gradual adjustment of the chemical admixing.
  • the adjusting element 9 is adjustable or displaceable in particular by means of the rotary handle 8, particularly preferably in the axial direction or parallel to the dispensing direction A of the foam device 1.

  • the adjusting element 9 is adjustable in such a way that the chemical admixing or supply can also be blocked. This position is shown in Fig. 2.
  • a helical slotted guide 13 For adjusting the adjusting element 9, in particular geared coupling with the rotary handle 8, in particular a helical slotted guide 13 is provided. In particular, this engages the longitudinally displaceable, for example, in a groove, guided actuator 9 with a radial projection 14 in a formed on the inner surface of the rotary handle 8, preferably helically extending groove 15, so that turning the rotary handle 8, the desired axial displacement of the control element 9 causes.
  • the chemical admixture or the valve device 7 or the rotary handle 8 is only adjustable in stages or latching.
  • the partially transparent, schematic plan view according to FIG. 3 illustrates, in particular, the preferred helical slide guide 13.
