Abstract

Druckmittelzylinder mit verstellbarem Hub, in welchem ein zumindest einseitig innerhalb eines Zylindergehäuseabschnitts (1) mit Druckmittel beaufschlagbarer Kolben (7) axial bewegbar angeordnet ist, an dem eine aus dem Zylindergehäuseabschnitt (1) zu einer Stirnseite hin austretende Kolbenstange (3) für eine Kraftübertragung befestigt ist, wobei koaxial benachbart an der gegenüberliegenden Stirnseite des Zylindergehäuseabschnitts (1) ein Hubeinstellabschnitt (2) angeordnet ist, in welchen die verlängerte Kolbenstange (3) mit einem endseitigen Anschlag (10) hineinragt, der mit mindestens einem in Form eines im wesentlichen orthogonal zur Längsachse der Kolbenstange (3) an dem Hubeinstellabschnitt (2) angebrachten Sperrdruckmittelzylinder (4a; 4b) zur Hubbegrenzung zusammenwirkt, wobei der Sperrdruckmittelzylinders (4a; 4b) eine endseitig abgewinkelte Kolbenstange (11) aufweist, die mit einem korrespondierenden Radialschlitz (12) an dem Hubeinstellabschnitt (2) zur Hubbegrenzung zusammenwirkt
