AxialkolbenpumpeAxial piston pump

Die Erfindung betrifft eine Axialkolbenpumpe mit zwei gleichsinnig von der gleichen Achse angetriebenen Taumel-Scheiben und den den Taumelscheiben zugeordneten in einer Zylindertrommel verschiebbaren Kolben. Bei einer bekannten Pumpe dieser Bauart werden die Taumelscheiben annähernd oder genau um 90° gegeneinander versetzt. Die Erfindung besteht darin, daß Elemente so gegeneinander versetzt sind, daß die Hubbewegungen gegenüberliegender Kolben entsprechend der halben Teilung gegeneinander verschoben sind. Damit bleiben die Massenkräfte annähernd ausgeglichen und der Gleichförmigkeitsgrad der Druckmittelförderung wird erhöht. Bei einer AusführungBform der Erfindung, bei der die Kolben gegenläufig in den gleichen Bohrungen einer Zylindertrommel verschiebbar sind, erfolgt der Kolbenantrieb durch um den halben Teilungswinkel gegeneinander versetzte Taumelscheiben. Bei einer anderen Ausführungsform, bei der symmetrisch gegeneinander geneigte Taumelscheiben zwischen den Zylindertrommeln angeordnet sind, sind die Zylindertrommeln um den halben Teilungswinkel gegeneinander verdreht.The invention relates to an axial piston pump with two swash plates driven in the same direction by the same axis and the piston which is assigned to the swash plates and is displaceable in a cylinder drum. With a well-known This type of pump will approximate the swashplate or offset from each other by exactly 90 °. The invention consists in that elements offset from one another are that the stroke movements of opposing pistons are shifted against each other according to half the division are. This means that the inertial forces and the degree of uniformity of the pressure medium delivery remain approximately balanced will be raised. In an embodiment of the invention, in which the pistons rotate in opposite directions in the the same bores of a cylinder drum are displaceable, the piston is driven by swash plates offset from one another by half the pitch angle. At a Another embodiment, in the symmetrically mutually inclined swash plates between the cylinder drums are arranged, the cylinder drums are rotated against each other by half the pitch angle.

In der Zeichnung sind die Abbildungen 1 und 2 Ausführungsbeispiele der Erfindung, schematisch dargestellt. In the drawing, Figures 1 and 2 exemplary embodiments of the invention are shown schematically.

In einem nicht dargestellten Gehäuse ist die Antriebswelle 1 drehbar gelagert, auf die die Taumelscheiben 2 und 3 um den halben Winkel der Zylinderteilung verdreht fest aufgekeilt sind. In dem Gehäuse ist auch die Zylinder-The drive shaft 1, onto which the swash plates 2 and 3 rotated by half the angle of the cylinder pitch are firmly wedged. In the housing is also the cylinder

In the cylinder bores 5, the pistons 6 and 7 move in opposite directions.

In Abbildung 2 ist das Gehäuse mit 8 bezeichnet und enthält die beiden um die halbe Teilung der Zylinderbohrungen gegeneinander versetzten Zylindertrommel^ In den Zylindertrommeln ist die Pumpenwelle 1o gelagert· Die Taumelscheiben 11 sind symmetrisch gegeneinander geneigt und fest auf der Welle 1o aufgekeilt.
