Description

Bei als Pumpe oder. Motor wirkenden Flüssigkeits;etrieben mit im Kreise und parallel angeordneten Kolben nach Patent 823 239, deren Achsen aber auch auf einem Kegelmantel angeordnet sein können, ist vorgeschlagen worden, die balligen Kolbenköpfe auf eine Kegelfläche als Führungsbahn wirken zu lassen. Hierbei wird aber bald eine Grenze erreicht, bei dü-r eine weitere Leistungssteigerung nicht möglich ist, da der vom Druck der Betriebsflüssigkeit abhängige spezifische Flächendruck zwischen Kolbenkopf und Führungsbahn unzulässige Werte erreicht.With as a pump or. Motor acting liquid; driven with in a circle and pistons arranged in parallel according to patent 823 239, but their axes also have a conical shell can be arranged, it has been proposed that the convex Let piston heads act on a conical surface as a guideway. Here is but soon reached a limit, with no further increase in performance is possible because the specific surface pressure depends on the pressure of the operating fluid Inadmissible values reached between the piston head and the guideway.

Gemäß der Erfindung gelingt es, bei solchen Flüssigkeitsgetrieben einen höheren Druck der Betriebsflüssigkeit zuzulassen und damit eine Leistungssteigerung zu erzielen, und zwar dadurch, daß die Führungsbahn für die balligen Kolbenköpfe nach Art einer Kugelschale oder ähnlich gekrümmt ist. Hierdurch läBt sich eine größere Auflagefläche für die Kolbenköpfe erzielen, die eine Erhöhung des Betriebsdruckes und damit eine höhere Leistung ergibt.According to the invention, it is possible to use such fluid drives to allow a higher pressure of the operating fluid and thus an increase in performance to achieve, namely that the guide track for the spherical piston heads is curved in the manner of a spherical shell or similar. This allows a larger Achieve contact surface for the piston heads, which increases the operating pressure and thus results in a higher performance.

Die Zeichnung zeigt im Längsschnitt ein vereinfachtes Ausführungsbeispiel der Erfindung, und zwar ein als Motor wirkendes Flüssigkeitsgetriebe. Auf der einerseits im Gehäuse i und andererseits im Gehäusedeckel 2 gelagerten Antriebswelle 3 ist der Kolbenträger ,4 mit Hilfe des Keiles 5 befestigt. Der Kolbenträger ,4 ist mit Zylinderbohrungen für die im Kreise und parallel angeordneten Kolben 6 . versehen. Die Kolbenköpfe 7 der Kolben 6 sind ballig abgedreht und wirken auf die nach Art einer Kugelschale gekrümmte Führungsbahn 8, die in die im Gehäusedeckel 2 drehbar gelagerte, exzentrisch zur Antriebswelle angeordnete Führungsscheibe 9 eingearbeitet ist. Die Betriebsflüssigkeit wird bei io unter Druck zu- und bei i i entspannt abgeführt. Die Wirkungsweise selbst ist im übrigen dem Fachmann bekannt.The drawing shows a simplified embodiment in longitudinal section of the invention, namely a fluid transmission acting as a motor. On the one hand in the housing i and on the other hand in the housing cover 2 mounted drive shaft 3 the piston carrier, 4 fastened with the aid of the wedge 5. The piston carrier, 4 is with Cylinder bores for the pistons 6 arranged in a circle and in parallel. Mistake. The piston heads 7 of the pistons 6 are turned crowned and act on the according to Art a spherical shell curved guide track 8 which can be rotated into the housing cover 2 incorporated guide disk 9 arranged eccentrically to the drive shaft is. The operating fluid is supplied under pressure at io and discharged under pressure at i i. The mode of action itself is otherwise known to the person skilled in the art.
