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. A ring piston machine has one with one in one Housing rotatably connected shaft rotatably connected toothed rotor and an annular piston whose teeth number is one tooth larger than that of the rotor, so that displacement chambers are formed between the teeth. There are also inflow and outflow channels in the housing or the shaft, face plates and at least one with inlet and Exhaust control openings provided on the rotor and the Ring piston on the side of the control disc and one on inner ring with projections see its center line with the center axis of the rotor coincides and on the inside with that of Match edged and on its outside with the front jumps corresponding recesses provided ring piston rolls in such a way that its central axis is a Kreisbe movement around the fixed central axis of the rotor describes. To the efficiency of the ring piston machine to increase and to reduce wear between between rotor and ring piston the supporting force between the rotor and ring piston in which the torque transmission is not reducing the sliding area are the projections of the Housing rings and the recesses of the annular piston formed by involute or cycloid gears and the point of engagement between the external teeth of the ring piston and the toothing of the housing ring and the Torque transfer point between the toothed rotor and the ring piston are in the area of the suction and Diameter line separating pressure chambers.
