Abstract

Ein Druckmittelzylinder (1) weist eine in axialer Richtung abgedichtet aus dem Zylinder (2) geführte, mit dem Kolben (3) mitbewegte Kolbenstange (4) auf, die ein längserstrecktes, unterschiedlich magnetisierte Zonen aufweisendes Indikatorelement (6) trägt, das durch eine im Bereich der Herausführung (7) der Kolbenstange (4) angeordnete Sensoreinrichtung (10) zur Ermittlung der Kolbenposition abtastbar ist. Zur Vereinfachung der Herstellung und zur Erleichterung der Abdichtbarkeit der Kolbenstange bei möglichst unbeeinflußter Festigkeit derselben ist das Indikatorelement (6) in einer in der Kolbenstange (4) im wesentlichen zentral angeordneten Axialbohrung (15) untergebracht.
