Abstract
Description
Bei der Abb. 1 wird die Flüssigkeit durch die Öffnung 3 in die Pumpe gesaugt. Durch die Drehung der Pumpscheibe 2 die von der Antriebswelle 5 angetrieben wird und durch die, durch die Drehung der Pumpscheibe 2 gegen das Pumpgehäuse 1 gedrückten, frei beweglichen Schieber 6 wird die Flüssigkeit zur Öffnung 4 befördert und durch diese aus der Pumpe hinausgedrückt.In Fig. 1, the liquid is sucked through the opening 3 into the pump. By the rotation of the pump disk 2 which is driven by the drive shaft 5 and by the freely movable slide 6 , which is pressed against the pump housing 1 by the rotation of the pump disk 2 , the liquid is conveyed to the opening 4 and is pressed out of the pump by this.
Da der Mittelpunkt vom Pumpgehäuse 1 vom Mittelpunkt der Pumpscheibe 2 abweicht vergrößert sich zunächst das Volumen zwischen den einzelnen Schiebern 6. Dadurch wird Flüssigkeit durch die Öffnung 3 angesaugt. Durch weiteres Drehen der Pumpscheibe 2 verkleinert sich dann der Zwischenraum zwischen den Schiebern 6 wieder, die Flüssigkeit wird durch die Öffnung 2 hinausgepreßt.Since the center of the pump housing 1 deviates from the center of the pump disk 2 , the volume between the individual slides 6 initially increases. This draws liquid through the opening 3 . By further turning the pump disk 2 , the space between the slides 6 is reduced again, the liquid is pressed out through the opening 2 .
Während die Pumpscheibe 2 starr ist, ist das Pumpgehäuse schwenkbar. (Bei starrem Pumpgehäuse 1 und schwenkbarer Pumpscheibe 2 würde die Pumpe genauso funktionieren. Jedoch ist diese Variation wegen des größeren technischen Aufwands nicht sinnvoll.)While the pump disk 2 is rigid, the pump housing can be pivoted. (With a rigid pump housing 1 and a swiveling pump disk 2 , the pump would work in the same way. However, this variation is not useful because of the greater technical complexity.)
Wird nun das Pumpgehäuse 1 wie in Abb. 2 geschwenkt ist der Abstand zwischen Pumpgehäuse 1 und Pumpscheibe 2 und somit auch das Volumen zwischen den Schiebern 6 überall in der Pumpe gleich. Die in der Pumpe befindliche Flüssigkeit wird innerhalb der Pumpe im Kreis bewegt. Es erfolgt keine Förderung.If the pump housing 1 is now pivoted as in Fig. 2, the distance between the pump housing 1 and the pump disk 2 and thus also the volume between the slides 6 is the same everywhere in the pump. The liquid in the pump is circulated within the pump. There is no funding.
Bei der, in der Zeichnung dargestellten Variante, sind die Form von Pumpgehäuse 1 und Pumpengehäuse 8 genau aufeinander abgestimmt.In the variant shown in the drawing, the shape of the pump housing 1 and pump housing 8 are precisely matched to one another.
In Abb. 3 ist die Förderrichtung umgekehrt. Das Prinzip ist das Gleiche wie bei Abb. 1.In Fig. 3 the conveying direction is reversed. The principle is the same as in Fig. 1.
Da jede Stellung des Pumpgehäuses 1 zwischen den Stellungen Abb. 1 und Abb. 3 möglich ist, ist auch ein Verringern bzw. Erhöhen der Fördermenge stufenlos und unter Last bei gleicher Pumpendrehzahl und Drehrichtung möglich.Since any position of the pump housing 1 between the positions Fig. 1 and Fig. 3 is possible, a reduction or increase in the delivery rate is stepless and possible under load with the same pump speed and direction of rotation.
Das äußere Pumpengehäuse 8 in dem die Antriebswelle 5 gelagert ist, dient gleichzeitig als Deckplatte und Bodenplatte für die Pumpe. (Deck- und Bodenplatte sind in der Zeichnung nicht abgebildet.)The outer pump housing 8 in which the drive shaft 5 is mounted serves at the same time as a cover plate and base plate for the pump. (The top and bottom plates are not shown in the drawing.)
Der Zwischenraum zwischen dem Pumpgehäuse 1 und dem äußeren Pumpengehäuse 8 ist zweckmäßigerweise mit der gleichen Flüssigkeit aufgefüllt, die in der Pumpe gefördert wird. Auf diese Weise ist es nicht notwendig, daß das schwenkbare Pumpgehäuse 1 zum äußeren, starren Pumpengehäuse 8 vollkommen dicht ist. The space between the pump housing 1 and the outer pump housing 8 is expediently filled with the same liquid that is conveyed in the pump. In this way, it is not necessary that the pivotable pump housing 1 is completely sealed to the outer, rigid pump housing 8 .
Weitere mögliche Schieberformen 6 sind in Abb. 4 und Abb. 5 dargestellt.Further possible slide shapes 6 are shown in Fig. 4 and Fig. 5.
Da das Pumpgehäuse 1 innerhalb des äußeren Pumgengehäuses 8 geschwenkt wird, ist es sinnvoller die Öffnungen 3 und 4, nicht wie auf der Zeichnung vereinfacht dargestellt in das Pumpgehäuse 1 zu machen, sondern in das äußere Pumpengehäuse 8 d. h. in die Deck- bzw. in die Bodenplatte. Vertiefungen in der Deck- und Bodenplatte (Pumpeninnenseite) können die Flüssigkeitsförderung noch verbessern.Since the pump housing 1 is pivoted within the outer pump housing 8 , it makes more sense to make the openings 3 and 4 , not as shown in the drawing in the pump housing 1 , but in the outer pump housing 8, ie in the cover or in the Base plate. Recesses in the top and bottom plate (inside of the pump) can further improve the liquid delivery.
Durch spezielle Formgebung von Schieber 6 und Pumpgehäuse 1 (Innenwand) kann bewerkstelligt werden, daß sich auch bei hoher Drehzahl immer z. B. bei der Förderung von Öl ein Ölfilm zwischen Pumpgehäuse 1 und Schieber 6 preßt. Auf diese Weise wird der Verschleiß erheblich reduziert.By special design of slide 6 and pump housing 1 (inner wall) can be accomplished that even at high speed z. B. in the production of oil presses an oil film between the pump housing 1 and slide 6 . This significantly reduces wear.
