Abstract
A fluidic nozzle which is flown through by a singular injection jet and which periodically deflects the injection jet. The nozzle has a nozzle channel, whose cross section is expanded in relation to the injection jet, and with control openings opening into the nozzle channel downstream close to the neck of the nozzle for injecting a control fluid that brings about the deflection of the jet. The nozzle channel has a channel cross section, which is two-dimensionally expanded in height and width in relation to the cross section of the jet, with a cross-section contour corresponding to the desired distribution cross section, and it is provided with a number of control openings. The control openings are arranged offset in relation to one another in the circumferential direction of the nozzle channel and are activated one after another in sequence to generate a jet movement rotating along the circumference of the nozzle channel.
