Abstract

Das vor dem Zusammenbau glatte Zylinderrohr (1) eines Arbeitszylinders, welches im zusammengebauten Zustand mit seinen Enden über bundartige Haltebereiche (16) an Ansätzen (17) von Deckel- (3) und Bodenteil (2) des Arbeitszylinders greift und in axialer Richtung gesehen außerhalb dieser Haltebereiche (16) jeweils in nutartige Vertiefungen (19) der Ansätze (17) verpreßt ist, weist in den endseitigen Verpressungsbereichen (20) auf der Außenseite eine mitverpreßte, bundartige Verstärkung (21) auf, welche bevorzugt von einem vor dem Verpressen aufgesetzten Haltering (22) gebildet ist. Damit kann die einfach und kostengünstige Verbindung zwischen Zylinderrohr (1) und Deckel- bzw. Bodenteil (2, 3) auch bei hinsichtlich ihrer Wandstärke relativ dünnen Zylinderrohren (1) angewandt werden.
