Abstract
In order to obtain a flat jet having a particularly uniform distribution of pressure in a flat jet nozzle for a high-pressure cleaning device with an outlet opening and a flow channel arranged upstream of and opening into this outlet opening, it is suggested that the flow channel and the outlet opening have a circular cross section transversely to the direction of flow and be arranged concentrically to one another, that the flow channel narrow conically in the direction of flow and merge into a circular-cylindrical section located upstream in front of the outlet opening, the end of this section forming the outlet opening, and that pocket-like extensions of the flow channel be arranged on diametrally opposite sides of the flow channel in the region where the conical section of the flow channel merges into the circular-cylindrical section, these extensions being arranged and designed symmetrically to one another, extending essentially over the entire diameter of the circular-cylindrical section and having a deflecting surface conducting part of the liquid flowing through the conical section essentially transversely into the cylindrical section.
