Description

Flüssigkeitssteuerung für Zahnradpumpen mit zur Leistungsänderung achsialer Verstellung des einen Zahnrades gegen das andere. Die Erfindung betrifft eine Flüssigkeitssteuerung für Zahnradpumpen mit zur Leistungsänderung achsialer Verstellung des einen Zahnrades gegen das andere. Das Neue besteht in einer an sich bekannten Einrichtung, welche den Zu- und Abfluß der Flüssigkeit selbsttätig absperrt, sobald das zu verstellende Zahnrad eine der Verstellung des Steuerschiebers entsprechende Verstellung erhalten hat. Hierdurch wird eine große Genauigkeit in der Verstellung erreicht, was bei Zahnradpumpen mit Leistungsänderung durch achsiale Verstellung des einen Zahnrades regen das andere von besonderer Bedeutung ist.Fluid control for gear pumps with to change the performance axial adjustment of one gear against the other. The invention relates to a fluid control for gear pumps with an axial change in output Adjustment of one gear against the other. The new consists of one in itself known device, which automatically shuts off the inflow and outflow of the liquid, as soon as the gear to be adjusted has a corresponding adjustment of the control slide Has received pretense. This results in a high degree of accuracy in the adjustment achieved, which is achieved with gear pumps with a change in output through axial adjustment of the one gear stimulate the other is of particular importance.

Die in der Zeichnung dargestellte Erfindung wirkt in folgender Weise: Die aus der Druckleitung der Pumpe oder aus sonst geeigneter Quelle nach der Richtung i() strömende Flüssigkeit wird durch die an sich bekannte Schiebervorrichtung 17 geführt, so daß die zu verstellenden Teile der Zahnradpumpe, Welle 18, Zahnrad i9, Verschlußkörper 2o und Scheibe 2i eine der Verstellung des Schiebers 22 entsprechende Verstellung erhalten. Wird z. B. der Schieber 22 in der Richtung 23 verstellt, so strömt die Flüssigkeit durch das Rohr 24 in den Hohlraum 25 des Pumpengehäuses und verschiebt den Körper 2o, die Scheibe 21 und das Zahnrad i9 mit der Welle 18 in der Richtung 26, wobei die Flüssigkeit aus dem entgegengesetzten Hohlraum 27 durch das Rohr 28 und die Schiebervorrichtung 17 in der Richtung 29 abströmt. Der doppelarmige Hebel 30 mit dem festen Drehpunkt 34 welcher an den Bund 32 der Welle 18 angreift, verschiebt dabei den zweiten Schieber 33 und sperrt hierdurch den Zufluß der Flüssigkeit ab, sobald die Welle 18 die durch den Schieber 22 bedingte Lage erreicht hat.The invention shown in the drawing works in the following way: The liquid flowing from the pressure line of the pump or from another suitable source in the direction i () is passed through the known slide device 17, so that the parts of the gear pump, shaft to be adjusted 18, gear wheel i9, closure body 2o and disk 2i receive an adjustment corresponding to the adjustment of the slide 22. Is z. B. adjusted the slide 22 in the direction 23, the liquid flows through the tube 24 into the cavity 25 of the pump housing and moves the body 2o, the disc 21 and the gear i9 with the shaft 1 8 in the direction 26, the Liquid flows off from the opposite cavity 27 through the pipe 28 and the slide device 17 in the direction 29. The double-armed lever 30 with the fixed pivot point 34, which engages the collar 32 of the shaft 18, moves the second slide 33 and thereby blocks the flow of liquid as soon as the shaft 18 has reached the position caused by the slide 22.

Anstatt der Schiebervorrichtung 17 kann auch ein Vierweghahn verwendet werden.Instead of the slide device 17 , a four-way valve can also be used.
