Abstract

Die Erfindung bezeichnet einen fluidbetriebenen, vorzugsweise einfach wirkenden Arbeitszylinder mit führungsseitiger Dämpfung, dessen Dämpfungsstrecke und Dämpfungscharakteristik dem jeweiligen Einsatzgebiet einfach anpaßbar ist, keine mechanisch wirkenden Bauteile aufweist, keine zusätzlichen äußeren oder inneren Verbindungen mit hohem Fertigungsaufwand oder großer radialer Ausdehnung benötigt und durch eine progressive Dämpfungscharakteristik die schonende Bewegung von Massen bzw. Kräften in getriebetechnischen Systemen ermöglicht sowie kostengünstig herstellbar ist. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß ein Arbeitszylinder (1) aus einem Zylinderrohr (3) und einem mit diesem verbundenen Dämpfungsrohr (4) besteht und, daß das Dämpfungsrohr (4) an seiner Innenmantelfläche (25) eine sich über dessen gesamte Länge erstreckenden Abströmkerbe (23) aufweist, deren Mittelachse (24), gegenüber der Zentralachse (2) des Arbeitszylinders (1), in einem Winkel mit dem Wert tan =0,02 bis 0,3 geneigt ist.
