Abstract

Eine Ringkolbenmaschine weist einen mit einer in einem Gehäuse drehbar gelagerten Welle drehfest verbundenen verzahnten Rotor und einen Ringkolben auf, dessen Zähne­ zahl um einen Zahn größer ist als die des Rotors, so daß zwischen den Zähnen Verdrängungskammern gebildet sind. Weiterhin sind Zu- und Abflußkanäle in dem Gehäuse oder der Welle, Stirnscheiben und mindestens eine mit Einlaßund Auslaßsteueröffnungen versehene, an dem Rotor und dem Ringkolben seitlich anliegende Steuerscheibe und ein auf sei­ ner Innenseite Vorsprünge aufweisender Gehäusering vorge­ sehen, dessen Mittellinie mit der Mittelachse des Rotors zusammenfällt und auf dessen Innenseite der von diesem mit Spiel eingefaßte und auf seiner Außenseite mit den Vor­ sprüngen entsprechenden Ausnehmungen versehene Ring­ kolben derart abrollt, daß dessen Mittelachse eine Kreisbe­ wegung um die feststehende Mittelachse des Rotors beschreibt. Um den Wirkungsgrad der Ringkolbenmaschine zu erhöhen und um zur Verringerung des Verschleißes zwi­ schen Rotor und Ringkolben die Abstützkraft zwischen Rotor und Ringkolben in dem nicht der Momentübertragung die­ nenden Gleitbereich zu verringern, sind die Vorsprünge des Gehäuserings und die Ausnehmungen des Ringkolbens durch Evolventen- oder Zykloidenverzahnungen gebildet und der Eingriffspunkt zwischen der Außenverzahnung des Ring­ kolbens und der Verzahnung des Gehäuserings und der Momentübertragungspunkt zwischen dem verzahnten Rotor und dem Ringkolben sind in den Bereich einer die Saug- und Druckräume trennenden Durchmesserlinie verlagert.
