Abstract

Die Erfindung betrifft einen Druckzylinder (1) umfassend ein Zylindergehäuse (2) mit einem Zylinderrohr (5), einem Zylinderboden (8) sowie einer Stangenführungseinheit (9), welche zusammen einen Zylinderraum (10) definieren, und einen Kolben (3) sowie eine Kolbenstange (4). Ein erster Druckmediumanschluss (14) steht über eine erste Druckmediumleitvorrichtung (16) mit einem stangenführungsseitigen Zylinderteilraum (12) in Strömungsverbindung. Die Kolbenstange (4) ist in der Stangenführungseinheit (9) an einer ersten Kolbenstangenführungsvorrichtung (13) geführt. Die erste Kolbenstangenführungsvorrichtung (13) ist auf der dem Zylinderboden (8) zugewendeten Seite der Stangenführungseinheit (9) angeordnet und weist eine erste Führungsfläche (24) auf. Die erste Druckmediumleitvorrichtung (16) weist im Bereich der ersten Kolbenstangenführungsvorrichtung (13) zumindest einen zwischen der Kolbenstange (4) und der ersten Führungsfläche (24) ausgebildeten Leitkanal (25) auf.
