Abstract

Bei einer Kolben-Zylinder-Einheit mit einer Kolbenendlagen­ dämpfung, die einen an der Stirnfläche des Kolbens (15) vor­ springenden Dämpfungskolben (31) aufweist, der unter Bildung eines Dämpfungsspaltes (38) in einen am zugekehrten Zylinder­ ende vorgesehenen Dämpfungsraum (32) einfahrbar ist, ist für die Einleitung einer Rückhubbewegung des Kolbens (15) ein Strömungsweg vorgesehen, der vom Anschluß (25) für Drucköl unter Umgehung des Dämpfungsspalts (38) zum an die Hauptkol­ benfläche (29) des Kolbens (15) angrenzenden Druckraum (40) führt und ein Rückschlagventil (47) enthält. Dieser Strömungs­ weg erstreckt sich innerhalb des Kolbens (15) zwischen einer Eintrittsöffnung am vorderen Ende (45) des als hohle Hülse ausgebildeten Dämpfungskolbens (31) und einen vom Innenraum (43) dieser Hülse nach außen führenden Durchbruch (55).
