Abstract

Die Erfindung betrifft eine Düseneinheit (1) zum Zerstäuben von Flüssigkeiten, wobei eine Flüssigkeitsdüse (2) mit einer Luftdüse (3) für Außenmischung kombiniert ist. Um eine Düseneinheit (1) zu schaffen, mit der auch auf größere Spritzentfernungen ein sauberes Spritzbild erzielbar ist, wird vorgeschlagen, eine Flüssigkeitsdüse (2) mit einem scheibenförmigen oder flachen Spritzbild mit einer Luftdüse (3) mit einem kegelförmigen Spritzbild zu kombinieren.

Figure 00000001
The invention relates to a nozzle unit (1) for atomising liquids, wherein a liquid nozzle (2) is combined with an air nozzle (3) for external mixing. In order to create a nozzle unit (1) with which a clean spray pattern can be achieved even at larger spray distances, it is proposed to combine a liquid nozzle (2) with a disk-shaped or flat spray pattern with an air nozzle (3) with a conical spray pattern.
