Abstract
Die Erfindung betrifft eine hydrostatische Maschine, insbesondere Axialkolbenmaschine, mit einer Triebwelle, die in einem Gehäuse drehbar gelagert eine Gehäusewand durchsetzt, wobei ein Spalt zwischen Triebwelle und Gehäusewand durch ein Radialwellendichtsystem abgedichtet ist, welches einen Radialwellendichtring und eine Gegenlauffläche aufweist, deren Oberfläche eine hydrodynamische Rückförderstruktur aufweist. Es stellt sich die Aufgabe, eine hydrostatische Maschine, insbesondere Axialkolbenmaschine der der eingangs genannten Art zu schaffen, die ein besonders beständiges Radialwellendichtsystem mit hoher Dichtigkeit und besonders geringem Leckageverhalten aufweist. Dies wird dadurch erreicht, indem die Rückförderstruktur mit einer harten diamantähnlichen Oberflächenbeschichtung versehen ist.
