Abstract
Description
Die Erfindung betrifft eine Flügelzellenpumpe, insbesondere zur Kraftstoffförderung, mit einem mehrere Flügel aufweisenden Läufer, der von einem Außenring umgeben ist.The Invention relates to a vane pump, especially for fuel production, with a several wings having runners, that of an outer ring is surrounded.
Die aus dem Stand der Technik bekannten Flügelzellenpumpen sind nicht für die Förderung dünnflüssiger Medien, wie beispielsweise Kraftstoff, geeignet. Die Fliehkraft, welche die Flügel im Betrieb gegen den Außenring drückt, reicht beim Startvorgang eines Verbrennungsmotors nicht aus, um eine ausreichende Abdichtung im Anliegebereich zwischen den Flügeln und dem Außenring sicherzustellen. Bisher löst man dieses Problem dadurch, dass man mit einer Handpumpe einen Druck aufbaut, welcher die Flügel gegen den Außenring drückt. Wenn jedoch vergessen wird, die Handpumpe zu betätigen, treten Betriebsstörungen auf. Deshalb werden bisher hauptsächlich Zahnradpumpen für die Kraftstoffförderung verwendet. Zahnradpumpen sind jedoch im Vergleich zu Flügelzellenpumpen verschleiß- und wartungsanfälliger. Radialkolbenpumpen kommen als Alternative ebenfalls nicht in Betracht. Sie sind im Vergleich zu Flügelzellenpumpen relativ aufwändig.The Vane pumps known from the prior art are not for the Promotion of low-viscosity media, such as fuel, suitable. The centrifugal force, which the wings in operation against the outer ring suppressed, is not sufficient when starting an internal combustion engine to a sufficient seal in the contact area between the wings and the outer ring sure. So far This problem by using a hand pump pressure builds up the wings against the outer ring suppressed. However, forgetting to operate the hand pump will cause malfunction. Therefore, so far mainly Gear pumps for the fuel production used. Gear pumps, however, are compared to vane pumps wear- and more susceptible to maintenance. Radial piston pumps are also not considered as an alternative. They are compared to vane pumps relatively expensive.
Die Erfindung hat die Aufgabe, eine Flügelzellenpumpe der eingangs genannten Art dahingehend zu verbessern, das mit ihr unter Vermeidung der oben genannten Nachteile auch dünnflüssige Medien gefördert werden können.The Invention has the task of a vane pump of the beginning mentioned type to improve that with her while avoiding the above-mentioned disadvantages also low-viscosity media promoted can be.
Die Erfindung löst die gestellte Aufgabe mit einer Flügelzellenpumpe der eingangs genannten Art, die erfindungsgemäß eine Feder aufweist, mit welcher die Flügel radial gegen den Außenring gedrückt werden. Durch die Feder werden alle Flügel zu jedem Zeitpunkt gegen den Außenring gedrückt. Somit können auch dünnflüssige Medien, wie beispielsweise Kraftstoff oder Wasser gefördert werden. Die Betätigung einer Handpumpe kann außerdem zukünftig entfallen.The Invention solves the task with a vane pump of the beginning mentioned type according to the invention a spring has, with which the wings radially against the outer ring depressed become. By the spring, all wings against each other at any time the outer ring pressed. Thus, you can also low-viscosity media, such as fuel or water are promoted. The actuation of a Hand pump can as well future omitted.
Der Läufer kann an seinen Stirnseiten eine Ausnehmung aufweisen, in welche die Feder eingelegt werden kann. Die Feder hat somit einen sicheren Sitz im Läufer, so dass sie die Flügel zuverlässig gegen den Außenring drücken kann.Of the runner can have at its end faces a recess in which the spring can be inserted. The spring thus has a secure fit in the runner, so they are the wings reliable against the outer ring to press can.
Die Feder kann mehrere Windungen und eine zylindrische Form aufweisen. Mit dieser Federbauart werden in der Praxis sehr gute Ergebnisse erzielt.The Spring can have several turns and a cylindrical shape. With this type of spring are in practice very good results achieved.
Für eine optimale Anpressung der Flügel am Außenring hat es sich bewährt, wenn der Federdraht einen Durchmesser von maximal 0,5 Millimeter aufweist. Ein zu großer Durchmesser des Federdrahts erzeugt eine zu hohe Anpressung der Flügel an den Außenring. Somit ist es aufgrund der starken Reibung möglich, dass die Flügel am Außenring fressen.For an optimal Pressing the wings on the outer ring has it proven if the spring wire has a maximum diameter of 0.5 millimeters having. One too big Diameter of the spring wire produces too high contact pressure wing to the outer ring. Thus, it is possible due to the strong friction that the wings on the outer ring eat.
In einer weiteren Ausführungsform ist es auch möglich, dass die Feder ein Elastomerring ist. Der Elastomerring lässt sich sehr kostengünstig in großen Stückzahlen fertigen.In a further embodiment it is also possible that the spring is an elastomeric ring. The elastomer ring can be very inexpensive in big numbers finished.
In einer Weiterbildung der Erfindung kann eine Elastomermasse die Ausnehmung ausfüllen. Die Elastomermasse kann während der Montage der Flügelzellenpumpe schnell und kostengünstig in die Ausnehmung eingespritzt werden. Die Elastomermasse drückt die Flügel gegen den Außenring.In a development of the invention may be an elastomer mass the recess fill out. The Elastomer mass may during the assembly of the vane pump fast and inexpensive be injected into the recess. The elastomer mass presses the wing against the outer ring.
Damit die Feder die Flügel gut an den Außenring anpressen kann, ist es wichtig, dass die Feder gut an den Flügeln anliegt. Deshalb können die Flügel im Anliegebereich der Feder mit Kerben versehen sein.In order to the spring the wings good to the outer ring it is important that the spring fits snugly against the wings. That's why the wings be provided with notches in the contact area of the spring.
Die erfindungsgemäße Flügelzellenpumpe stellt ihre hervorragenden Eigenschaften beim Pumpen von dünnflüssigen Medien auch dann unter Beweis, wenn der Außenring als ein Exzenterring oder als ein Kurvenring ausgeführt wird.The inventive vane pump provides their outstanding properties when pumping low-viscosity media also proves if the outer ring as an eccentric ring or executed as a cam ring becomes.
Nachfolgend werden verschiedene Ausführungsbeispiele der erfindungsgemäßen Flügelzellenpumpe anhand der beiliegenden Zeichnungen näher erläutert.following Be different embodiments the vane pump according to the invention explained in more detail with reference to the accompanying drawings.
