Title
(DE) DÄMPFUNGSANORDNUNG
(EN) DAMPING ARRANGEMENT
(FR) DISPOSITIF D'AMORTISSEMENT
Abstract
(DE) Bei einer Dämpfungsanordnung zur Dämpfung/Tilgung von unerwünschten Druckschwingungen in einer hydraulischen Strecke, insbesondere zur Kupplungsbetätigung, umfassend einen Geberzylinder und einen Nehmerzylinder, die über eine von einem Fluid durchströmte Druckleitung hydraulisch miteinander verbunden sind, wobei eine koaxial zu der Druckleitung angeordnete Dämpfungs - /Tilgungseinrichtung (1) eingesetzt ist, ist erfindungsgemäß wenigstens ein weiteres Schwingungsdämpfungselement (2, 4) in die Dämpfungs - /Tilgungseinrichtung integriert.
(EN) For a damping arrangement for damping/suppressing undesired pressure oscillations in a hydraulic segment, in particular for clutch actuation, comprising a master cylinder and a slave cylinder, which are hydraulically connected to each other by means of a pressure line through which a fluid flows, wherein a damping/suppressing device (1) arranged coaxially with the pressure line is used, according to the invention, at least one further oscillation-damping element (2, 4) is integrated in the damping/suppressing device.
(FR) L'invention concerne un dispositif d'amortissement pour amortir/supprimer des oscillations de pression parasites dans une voie hydraulique, notamment pour l'actionnement d'un embrayage, comportant un maître-cylindre et un cylindre récepteur reliés hydrauliquement l'un à l'autre au moyen d'une conduite de pression parcourue par un fluide, un appareil d'amortissement/suppression (1) disposé coaxial par rapport à la conduite de pression étant prévu. Selon l'invention, au moins un élément d'amortissement d'oscillations supplémentaire (2, 4) est intégré à l'appareil d'amortissement/suppression.
