Description
Mehrere Verformungselemente 6 sind im kegelförmigen Innenraum 22 des Gehäuses 2 eingesetzt und liegen auf der Tragplatte 4 mit ihren kleineren Stirnflächen 61 auf. Diese Verformungselemente 6 umschließen einen durchgehenden Hohlraum 62, der aus einem Einlaufabschnitt 621 an der Eintrittsseite, einem Verformungsabschnitt 622 und einem Kalibrierabschnitt 623 besteht. Bei der Ausführung nach F i g. 3 hat der Hohlraum 62 in der ganzen Länge einen kreisrunden Querschnitt und einen spindelförmigen Verlauf. Die Größe des Hohlraum-Querschnitts ändert sich vom Einlaufabschnitt 621
