Abstract

Eine Vorrichtung dient zum Abdichten einer rotierenden Welle für den Einsatz unter Wasser. Sie weist Gleitringdichtungen auf, welche einen Arbeitsbereich gegenüber dem Wasser abdichten. Erfindungsgemäß sind die Gleitringdichtungen in Form von drei Gleitringen ausgebildet, wobei zwischen den drei Gleitringen zwei Bereiche angeordnet sind. Einer der Bereiche ist ein dem Wasser benachbarter mit einem ersten Medium gefüllter Dichtbereich und der andere der Bereiche ist ein dem Arbeitsbereich benachbarter Leckagebereich. In dem Dichtbereich wird das erste Medium auf einem Druckniveau gehalten, welcher höher als der Druck des benachbarten Wasser ist.
