19 und einer großen zentralen Öffnung 20, die andere 17 aus dünnerem Feinblech mit zur ersten Scheibe gleichliegenden peripheren Drall-Lappen 21 bzw. 19 and a large central opening 20, the other 17 made of thinner Thin sheet metal with peripheral twist tabs 21 or
22 und mit Drall-Lappen 23, die um eine kleinere Öffnung 24, beide im Bereich der großen Öffnung 20, liegen. 22 and with swirl flaps 23, which around a smaller opening 24, both in the area of the large opening 20.
Die peripheren Drall-Lappen in den Fig. 1 bis 8 sind sämtlich paarweise durch Schränken abgebogen. Es kann aber auch jeweils nur ein Lappen abgewinkelt sein.The peripheral swirl flaps in FIGS. 1 to 8 are all in pairs bent through cupboards. However, only one flap can be angled at a time be.
Die Drallscheiben sind erforderlichenfalls - in den Figuren nicht dargestellt - randlich z.B. mit Zacken oder durch Umbörteln mit einem Rand versehen, mit denen sie im Düsengehäuse beim Einpressen verankert werden. Es können aber auch im Innern des Düsengehäuses Noppen, Sicken oder Ringe zur formschlüssigen Verbindung mit den Drallscheiben vorgesehen sein.The swirl disks are if necessary - not in the figures shown - at the edge e.g. provided with spikes or by flanging with an edge, with which they are anchored in the nozzle housing during pressing. But it can also Inside the nozzle housing, knobs, beads or rings for a form-fitting connection be provided with the swirl disks.
Die Ausstülpungen nach den Fig. 6 und 7 können durch Tiefziehen geformt sein, nachdem zuvor in diesem Teil der Scheiben die Löcher eingestanzt wurden.The protuberances according to FIGS. 6 and 7 can be formed by deep drawing after the holes have been punched in this part of the discs.
Da bei der Kleinheit der Scheiben die Verformung bei relativ dicken Feinblechen nicht durchführbar ist, können wie Fig. 7 zeigt, die Drall-Lappen und Durchbrüche in Scheiben aus feineren Blechen angebracht sein, die dann von einem Stützring im Düsengehäuse getragen werden, der entsprechend den Verformungen in der dünneren Scheibe gleichliegende Öffnungen hat.Because with the smallness of the disks the deformation with relatively thick ones Thin sheet metal is not feasible, as FIG. 7 shows, the swirl tabs and Breakthroughs in disks made of finer sheet metal, which are then made by a Support ring are carried in the nozzle housing, which corresponds to the deformations in the thinner disc has openings that are identical to the thinner disc.
