Abstract (en)
The front-nozzle (10a) has a water inlet opening and a water outlet opening, where a fin system is arranged within the front-nozzle. An inlet region of the front-nozzle is provided without fin system. The front-nozzle is formed in a rotationally asymmetric manner. A water-inlet-side opening area (19) of the front-nozzle is greater than a water-inlet-side opening area of a rotationally symmetrical front-nozzle with the same center radius.
