Abstract
Description
Die Erfindung geht aus von einer Flügelzellenpumpe nach der Gattung des Anspruchs 1, wie in
Eine solche Flügelzellenpumpe ist durch die
Die erfindungsgemäße Flügelzellenpumpe mit den Merkmalen gemäß Anspruch 1 hat demgegenüber den Vorteil, dass die Druckbeaufschlagung der Innenbereiche der Nuten des Rotors durch die sich über den gesamten Umfang des Rotors erstreckende Ringnut verstärkt ist. Außerdem ist durch die Exzentrizität der Ringnut bezüglich der Drehachse des Rotors die radiale Erstreckung des Dichtbereichs zwischen der Ringnut und der Antriebswelle eine gezielte Vergrößerung der radialen Erstreckung des Dichtbereichs in einem Umfangsbereich des Rotors ermöglicht, wodurch die Leckage aus der Ringnut verringert werden kann.The vane pump according to the invention with the features of claim 1 has the advantage that the pressurization of the inner regions of the grooves of the rotor is reinforced by extending over the entire circumference of the rotor annular groove. In addition, by the eccentricity of the annular groove with respect to the axis of rotation of Rotor, the radial extent of the sealing area between the annular groove and the drive shaft allows a targeted increase in the radial extent of the sealing area in a peripheral region of the rotor, whereby the leakage from the annular groove can be reduced.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Flügelzellenpumpe angegeben.In the dependent claims advantageous refinements and developments of the vane pump according to the invention are given.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen
In den
In der Pumpenkammer ist wie in
Die Innenseite der Umfangswand 18 des Pumpengehäuses 10 ist exzentrisch zur Drehachse 13 des Rotors 20 ausgebildet, beispielsweise kreisförmig oder mit anderer Form. In wenigstens einer Gehäusestirnwand 14,16 ist wie in
In wenigstens einer Gehäusestirnwand 14,16 ist wie in
Die Verbindungsnut 40 kann beispielsweise radial oder geneigt zu einer Radialen bezüglich der Drehachse 13 von der Drucknut 34 nach innen verlaufen. Die Verbindungsnut 40 kann insbesondere derart verlaufen, dass diese sich in Drehrichtung 21 des Rotors 20 der Ringnut 38 annähert. Weiterhin kann die Verbindungsnut 40 schneckenförmig gekrümmt verlaufen. Die Verbindungsnut 40 mündet vorzugsweise einerseits zumindest annähernd tangential in die Drucknut 34 und/oder andererseits zumindest annähernd tangential in die Ringnut 38. Vorzugsweise mündet die Verbindungsnut 40 in den entgegen der Drehrichtung 21 des Rotors 20 weisenden Endbereich der Drucknut 34. Durch die Verbindung der Ringnut 38 mit der Drucknut 34 herrscht in der Ringnut 38 und damit in den mit dieser in Verbindung stehenden inneren Endbereichen der Nuten 24 des Rotors 20 ein erhöhter Druck, durch den die Anlagekraft der Flügel 26 an der Innenseite der Umfangswand 18 verstärkt wird, wodurch die Förderleistung der Flügelzellenpumpe verbessert wird. Durch den gekrümmten Verlauf der Verbindungsnut 40 wird außerdem bei der Drehbewegung des Rotors 20 in dieser eine Schleppströmung erzeugt, die zu einer weiteren Druckerhöhung in der Ringnut 38 und damit den Nuten 24 führt, wodurch die Anpresskraft der Flügel 26 an die Umfangswand 18 weiter erhöht wird. Insbesondere erfolgt infolge dieser Schleppströmung bereits beim Anlaufen der Flügelzellenpumpe ein Druckaufbau in der Ringnut 38, so dass die durch die Flügelzellenpumpe bereits beim Anlaufen eine ausreichende Kraftstoffmenge fördert. Durch den gekrümmten Verlauf der Verbindungsnut 40 ist außerdem sichergestellt, dass die Flügel 26 sich bei der Drehbewegung des Rotors 20 annähernd tangential über die Verbindungsnut 40 bewegen, wodurch der Verschleiß der Flügel 26 und der Gehäusestirnwand 14,16 gering gehalten wird.The connecting
Es kann vorgesehen sein, dass nur in einer Gehäusestirnwand 14 oder 16 die Ringnut 38 und die diese mit der Drucknut 34 verbindende Verbindungsnut 40 angeordnet ist oder es können in beiden Gehäusestirnwänden 14 und 16 jeweils eine Ringnut 38 und eine Verbindungsnut 40 angeordnet sein, die dann vorzugsweise spiegelbildlich zueinander in den Gehäusestirnwänden 14 und 16 angeordnet sind. Es kann auch vorgesehen sein, dass in beiden Gehäusestirnwänden 14 und 16 jeweils eine Ringnut 38 angeordnet ist, jedoch nur in einem Gehäuseteil 14 oder 16 eine Verbindungsnut 40 angeordnet ist. Es kann außerdem vorgesehen sein, dass nur in einer Gehäusestirnwand 14 oder 16 die Saugnut 30 und/oder die Drucknut 34 ausgebildet ist, wobei die andere Gehäusestirnwand 16 bzw. 14 glatt ausgebildet ist, oder dass in beiden Gehäusestirnwänden 14 und 16 jeweils eine Saugnut 30 und/oder Drucknut 34 ausgebildet ist, die dann vorzugsweise spiegelbildlich zueinander in den Gehäusestirnwänden 14 und 16 angeordnet sind. Die Saugöffnung 28 und die Drucköffnung 32 ist dabei jedoch nur in einer Gehäusestirnwand 14 oder 16 vorgesehen, wobei in einer Gehäusestirnwand 14 die Saugöffnung 28 vorgesehen ist und in der anderen Gehäusewand 16 die Drucköffnung 32 vorgesehen ist. Bei der spiegelbildlichen Anordnung der Saugnuten 30 und Drucknuten 34 sowie der Ringnuten 38 und Verbindungsnuten 40 in beiden Gehäusestirnwänden 14 und 16 wird erreicht, dass der Rotor 20 und die Flügel 26 in axialer Richtung beidseitig zumindest annähernd gleich belastet sind, so dass keine oder nur eine geringe resultierende Kraft auf den Rotor 20 und die Flügel 26 in Richtung der Drehachse 13 wirkt. Die Tiefe der Ringnut 38 und der Verbindungsnut 40 in der Gehäusestirnwand 14,16 beträgt beispielsweise zwischen 0,1 und 2mm, wobei vorzugsweise die Breite der Nuten 38,40 größer ist als deren Tiefe.It can be provided that only in a
