(FR) CLAPET D'AMORTISSEMENT POUR UN AMORTISSEUR DE VIBRATIONS
Abstract
(DE)
Dämpfventil für einen Schwingungsdämpfer, umfassend einen Dämpfventilkörper, der mindestens einen Durchtrittskanal aufweist, dessen Austrittsöffnung von mindestens einer Ventilscheibe abgedeckt wird, wobei die Ventilscheibe von mindestens einem Elastomerelement in Schließrichtung vorgespannt wird, das sich an einer Stützscheibe abstützt, wobei das Elastomerelement einen Knotensteg aufweist, von dem aus sich mindestens zwei Federstege schräg erstrecken.
(EN)
The invention relates to a damping valve for a vibration damper, comprising a damping valve body having at least one through channel, the outlet opening of which is covered by at least one valve disk, wherein the valve disk is prestressed in the closing direction by at least one elastomer element which is supported on a support disk, wherein the elastomer element has a nodal web, from which extend at least two spring webs in an oblique manner.
(FR)
L'invention concerne un clapet d'amortissement pour un amortisseur de vibrations, comprenant un corps de clapet d'amortissement qui présente au moins un canal de passage dont l'ouverture de sortie est recouverte par au moins un disque de clapet, le disque de clapet étant précontraint dans le sens de la fermeture par au moins un élément élastomère qui s'appuie sur un disque de support, l'élément élastomère présentant une âme de nœud à partir de laquelle s'étendent obliquement au moins deux âmes de ressort.
