Abstract

Die Erfindung betrifft eine Vorrichtung zur Dämpfung von Druckschwingungen in einem hydraulischen Antriebssystem mit einem Senkbremsventil (11), bei dem in einer Abzweigung (13) der Steuerdruckleitung (12) zur Aufsteuerung des Senkbremsventils (11) eine Dämpfungsvorrichtung aus Drossel (29) und Druckspeicher (14) vorgesehen ist. Gemäß der Erfindung weist der Druckspeicher (14) eine oder mehrere Kammern auf, in die ein Füllkörper aus einem geschlossenzelligen Elastomermaterial eingebracht ist, das die Kammer(n) ausfüllt.
