Abstract

Eine Druckwasser-Spritzdüse für Hochdruckreinigung hat in Umkehrung bekannter Bauarten einen vom Druckwasser durchflossenen kleinen Durchmesser, dem ein geringfügig größerer, den Wasserstrahl nachzentrierender Durchmesser nachgeschaltet ist, so daß sich ein besonders scharfer Punktstrahl ergibt, der durch verschiedene Bauartmodifikationen in Parallel- und/oder Hintereinanderschaltung modifiziert werden kann.

Figure 00000001
Reversing known designs, a pressurized water spray nozzle for high-pressure cleaning has a small diameter through which pressurized water flows, which is followed by a slightly larger diameter that re-centers the water jet, so that a particularly sharp point jet results, which is due to various design modifications in parallel and / or series connection can be modified.
