Abstract (en)
The pressurised fluid jet leaves the nozzle channel (50) in the nozzle body and enters into a larger rectifying channel (58) in a direct axial extension of the nozzle channel so that the fluid parts are bundled together to form a concentrated jet. The ratio of the through-flow faces of the rectifying channel and nozzle is below 16. At least one by-pass flow device allows at least one by-pass current parallel to the central current through the nozzle channel whereby the fluid inlet and the start of the rectifying channel are connected. The fluid by pass can be switched on and off by a preferably infinitely adjustable fluid valve.

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. <IMAGE>
