Abstract
Kraftstoffpumpe (
Description
Die Erfindung betrifft eine Kraftstoffpumpe (
Derartige Pumpen sind aus der
Es ist weiter ein Transformator bekannt,
in dessen magnetischen Rückschlusskreis
ein Rotor angeordnet ist (
Der Erfindung liegt somit die Aufgabe zugrunde, eine Kraftstoffpumpe der eingangs genannten Art zu schaffen, um eine zuverlässige Methode zu finden, die Kraftstoffpumpe in ihrer Effizienz zu steigern, d. h., bei vorgegebenem Systemdruck den spezifizierten Durchflusswert einzustellen.The invention is therefore the object to create a fuel pump of the type mentioned in the introduction, to be reliable Finding a way to increase the efficiency of the fuel pump, d. i.e., the specified flow value for a given system pressure adjust.
Diese Aufgabe wird erfindungsgemäß dadurch
gelöst,
dass eine Veränderung
der Motordrehzahl über
den magnetischen Fluss erreicht wird. Der magnetische Fluss wird
durch Anbringung eines zusätzlichen
Rückschlusskörpers, der
gedreht und/oder verschoben werden kann, verstärkt oder abgeschwächt (
Die Rückschlussdicke des Motorgehäuses muss
so ausgelegt sein, dass ...
eine Übersättigung vorliegt, so daß durch
Anbringen des zusätzlichen
Rückschlusses
(
there is oversaturation, so that by adding the additional inference (
Der Vorteil der Erfindung besteht weiterhin darin, daß durch ein Verschieben oder Drehen (je nach Ausführung) der gewünschte Durchfluß im Arbeitspunkt erreicht wird und dann der zusätzliche Rückschluß durch Punktschweißen oder ähnlichem Verfahren an dem Motorgehäuse fixiert wird.The advantage of the invention is continue in that by a shifting or rotating (depending on the version) the desired flow in the operating point is reached and then the additional conclusion by spot welding or similar process on the motor housing is fixed.
Ein weiterer Vorteil der Erfindung
besteht darin, daß ein
ringförmig
geschlossener (
Es können mehrere Rückschlüsse gegeneinander angeordnet werden. Several conclusions can be drawn against each other to be ordered.
Der hier dargestellte Arbeitsablauf kann in dem Fertigungsprozeß vollautomatisiert ausgeführt werden, sodass damit die erforderliche Wirtschaftlichkeit gewährleistet ist.The workflow shown here can be fully automated in the manufacturing process be executed so that the necessary economy is guaranteed is.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben. Es zeigenEmbodiments of the invention are shown in the drawing and are described in more detail below. Show it
Gemäß
Durch die Öffnung im zusätzlichen Rückschluß kann dieser auf dem Motorgehäuse in radialer Richtung sowohl nach links als auch nach rechts gedreht werden.Through the opening in the additional This can be inferred on the motor housing rotated in the radial direction both to the left and to the right become.
Durch diese variabel ausgestalteten
Rückschlußringe (Größe und Dicke)
wird der Wirkungsgrad des Motors als auch der Pumpleistung durch das
Drehen oder Verschieben jeweils verstärkt oder abgeschwächt (
