Abstract

Eine Drehkolbenmaschine hat ein Gehäuse und einen Ringkolben, der mit einer relativ zu dem Gehäuse drehbaren Welle (20) drehfest verbunden und in einem zu der Welle (20) koaxialen Ringraum (38) des Gehäuses drehbar und axial verschiebbar geführt ist, wobei die axiale Endfläche des Ringraumes (38) und/oder des Ringkolbens als Wellenfläche (54) mit achsparalleler Amplitude und mindestens einem Wellenberg und einem Wellental ausgebildet ist und wobei an dem der Wellenfläche (54) zugekehrten Stirnende des Ringkolbens oder axialen Ende des Ringraumes mindestens ein zur Anlage an der Wellenfläche (54) bestimmter Wälzkörper (52) mit radial zur Kolbenachse gerichteter Drehachse gelagert ist, somit jeweils einen Einlass- und einen Auslasskanal (18, 19) in dem Gehäuse, die mit dem zwischen dem Ringkolben (22) und der Endfläche des Ringraumes (38) gebildeten Arbeitsraum der Drehkolbenmaschine in Verbindung stehen. Der mindestens eine Wälzkörper (52) ist in einer kolbenfesten oder gehäusefesten Tasche frei drehbar gehalten und stützt sich auf der der Wellenfläche (54) entgegengesetzten Seite an einer Laufscheibe (58) ab, die über ein Wälzkörperlager (60) koaxial zur Kolbenachse drehbar an dem Ringkolben bzw. dem Gehäuse gelagert ist.
