Description
Die Erfindung betrifft eine volumenstromvariable Rotorpumpe in einer im Oberbegriff des Anspruchs 1 erläuterten Ausbildung.The The invention relates to a volumetric flow variable rotor pump in one in the preamble of claim 1 explained training.
Rotorpumpen
dieser Art sind z. B. aus der
Der Erfindung liegt die Aufgabe zugrunde, bei solchen Rotorpumpen Veränderungen des theoretischen Fördervolumens auf anderer konstruktiver Basis zu bewerkstelligen.Of the Invention is based on the object in such rotor pumps changes the theoretical funding volume to accomplish on another constructive basis.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.These The object is achieved by the characterizing features of claim 1 solved.
Durch Verdrehen des scheibenförmigen Einstellgliedes aus seiner das Maximalvolumen der durch die Konturen von Zähnen und Zahnlücken der beiden Rotoren begrenzten Verdrängungskammer bestimmenden Nulllage lässt sich eine Veränderung des Kammervolumens zur Einstellung eines gewünschten theoretischen Fördervolumens bewerkstelligen.By Twisting the disc-shaped Adjusting member of his the maximum volume of the contours of teeth and tooth gaps the two rotors limited displacement chamber defining zero position let yourself a change of the Chamber volume for setting a desired theoretical delivery volume accomplish.
Nach einer solchen Neueinstellung des Einstell gliedes werden zwischen Saug- und Druckseite im Verlaufe des sich bei einer Drehung der Verdrängungskammer um eine Zahnteilung kontinuierlich verkleinernden Kammervolumens, aufgrund ungenügender Überdeckung, zwischen Saug- und Druckanschluss volumetrische Verluste vermieden, indem sich der für eine gewünschte Veränderung des theoretischen Fördervolumens vorzunehmenden Drehbewegung des Einstellgliedes zu seiner Neueinstellung eine entsprechende Relativbewegung der durch Außen- und Innenrotor gebildeten Rororbaugruppe durch Verdrehen des Stellringes überlagern lässt.To Such a readjustment of the adjusting member will be between Suction and pressure side in the course of a rotation of the displacement chamber around a tooth pitch continuously decreasing chamber volume, due to insufficient coverage, avoiding volumetric losses between suction and pressure connections, by himself for a desired one change the theoretical funding volume to be made rotary movement of the adjusting member to his new setting a corresponding relative movement of the outer and inner rotor formed Rororbaugruppe overlaid by turning the collar.
Das Verdrehen von Einstellglied und Stellring lässt sich auf verschiedene Weise erreichen, wobei die Merkmale des Anspruches 2 für die Rotorpumpe eine Seibstregelung ermöglicht, um zu vermeiden, dass beispielsweise in einem zu versorgenden Ölsystem einer Druckumlaufschmierung eines Verbrennungsmotors der Betriebsdruck nicht über eine zulässige Grenze ansteigen wird.The Twisting the setting member and adjusting ring can be done in different ways achieve, with the features of claim 2 for the rotor pump a Seibstregelung allows to avoid, for example, in an oil system to be supplied a pressure circulation lubrication of an internal combustion engine, the operating pressure not over one allowed Limit will rise.
Dies lässt sich mit Hilfe eines Druckregelventiles einrichten, durch das der Betriebsdruck begrenzt und überschüssig gefördertes Schmieröl in einem Nebenstrom zum Tank zurückgeführt wird.This let yourself set up by means of a pressure regulating valve, through which the operating pressure limited and excess funded oil is recycled in a side stream to the tank.
Zur Durchführung der einander zu überlagernden Drehbewegungen von Einstellglied und Stellring zur Veränderung des Volumenstromes ergibt sich eine vorteilhafte Konstruktion einer Betätigungsvorrichtung nach Anspruch 3, wobei die zur Verstellung von Einstellglied und Stellring vorgesehenen Stellkolben gemäß Anspruch 4 angeordnet sein können.to execution of each other overlaid Rotary movements of setting member and collar for change the volume flow results in an advantageous construction of a actuator according to claim 3, wherein the adjustment of adjustment and Adjusting ring provided actuating piston can be arranged according to claim 4.
Eine zu bevorzugende Kolbenausbildung hat hierbei Anspruch 5 zum Gegenstand, indem die Führung der Flachkolben die den durch Verdrehen zu verstellenden Komponenten der Rotorpumpe zugeordnet sind, innerhalb des Pumpengehäuses entlang eines Kreisabschnittes erfolgen wird. Eine solche Kolbenführung lässt sich in das Pum pengehäuse günstig integrieren und ermöglicht so eine besonders raumsparende Bauform für dasselbe.A preferred piston configuration here is the subject of claim 5, by the leadership the flat piston the components to be adjusted by turning associated with the rotor pump, within the pump housing along a Circular section will be done. Such a piston guide can be In the pen housing cheap integrate and allows such a particularly space-saving design for the same.
Um hierbei Stellring und Einstellglied von dem bei einer solchen Kolbenführung auf diese wirkenden Radialdruck zumindest weitgehend zu entlasten, wird für diese Teile eine Anordnung von Flachkolben gemäß den Ansprüchen 6 und 7 vorgeschlagen. Around here adjusting ring and adjusting member of the in such a piston guide This acting radial pressure is at least largely relieved for this Parts proposed an arrangement of flat piston according to claims 6 and 7.
