Abstract

Die Erfindung betrifft einen hydraulischen Zylinder mit Stoßsicherung, aufweisend ein Zylindergehäuse (1), in dem ein über eine Kolbenstange (10) angetriebener Kolben (4) axial verschiebbar angeordnet ist, sowie ggf. einen hohlzylindrischen Dämpfungskolben (11). Mittels unterschiedlicher Ausführungsformen wird eine ein- oder beidseitige Endlagendämpfung realisiert. Kolbenstange (10), Kolben (4) und Dämpfungskolben (11) können hohlzylindrisch ausgebildet sein.
