In der Figur sieht man einen Teil einer Hochdruckpumpe 1,
an die eine Kraftstoff-Förderpumpe 2 angebaut ist. Bei der
Kraftstoff-Förderpumpe 2 handelt es sich um eine
Zahnradpumpe. Das Pumpengehäuse 3 der Zahnradpumpe 2 dient
dabei als Gehäusedeckel der Hochdruckpumpe 1 und ist
mittels mehrerer Schrauben 4 fest mit dem Gehäuse 6 der
Hochdruckpumpe 1 verbunden. Ein 0-Ring 5 dichtet das als
Deckel dienende Gehäuse 3 der Zahnradpumpe 2 gegen das
Gehäuse 6 der Hochdruckpumpe 1 ab.In the figure you can see part of a
In dem Gehäuse 6 der Hochdruckpumpe 1 ist eine Nockenwelle
7, die zum Antrieb der Hochdruckpumpe 1 dient, drehbar
gelagert. Mit dem zu der Zahnradpumpe 2 gewandten Ende der
Nockenwelle 7 der Hochdruckpumpe 1 ist ein Hohlrad 8 mit
Hilfe einer Zentralschraube 9 und einem Federring 10
kraftschlüssig verbunden. Alternativ zu der
kraftschlüssigen Verbindung kann auch eine formschlüssige
Verbindung verwendet werden. Das Hohlrad 8 trägt eine
Skalenscheibe 11 für einen Drehwinkelsensor. Statt dessen
kann das Hohlrad 8 auch als Skalenscheibe ausgeführt sein.There is a camshaft in the
Das Hohlrad 8 befindet sich in Eingriff mit einem Ritzel
13, das an einem Ende einer Antriebswelle 12 der
Zahnradpumpe 2 kraft- oder formschlüssig montiert ist. An
dem anderen Ende der Antriebswelle 12 der Zahnradpumpe 2
ist ein erstes Pumpenzahnrad 15 angebracht. Die
Drehbewegung der Antriebswelle 12 der Zahnradpumpe 2 wird
über einen Mitnehmer 14 auf das erste Pumpenzahnrad 15
übertragen.The ring gear 8 is in engagement with a pinion
13, the at one end of a
Das erste Pumpenzahnrad 15 wirkt mit einem zweiten
Pumpenzahnrad 16 zusammen, um Kraftstoff zu fördern. Das
zweite Pumpenzahnrad 16 ist auf einem als Bestandteil des
Gehäuses 3 der Zahnradpumpe 2 ausgebildeten Achsstummel 18
gelagert. The
Die bei 19 angedeutete Pumpkammer wird auf der von der
Hochdruckpumpe 1 abgewandten Seite durch einen Pumpendeckel
20 dicht verschlossen. Die Abdichtung zwischen der
Pumpkammer 19 und dem Pumpendeckel 20 erfolgt über einen 0-Ring
21.The pump chamber indicated at 19 is on that of the

An dem Pumpendeckel 20 ist eine Handpumpe 22 befestigt, die
mit Hilfe von im Pumpendeckel 20 integrierten
Rückschlagventilen eine Handförderpumpeneinheit bildet. Mit
der Handförderpumpeneinheit kann die Pumpkammer 19 bzw. der
Pumpenraum 19 und das (nicht dargestellte)
Niederdruckleitungssystem entlüftet werden.A

Durch pumpenintegrierte Regeleinrichtungen kann die Fördermenge der Zahnradpumpe von 100 l pro Stunde bis 1000 l pro Stunde bei einer Drehzahl von 2 500 pro Minute eingestellt werden. Durch eine Saugdrosselung wird erreicht, dass der geförderte Volumenstrom nicht linear mit der Drehzahl ansteigt, sondern ab einer gewissen Pumpendrehzahl konstant ist. Im Gegensatz zum Anpassen der Fördermenge durch Absteuern über ein Druckregelventil wird bei der Saugdrossel weniger Leistung "vernichtet". Das führt zu einer geringeren Erwärmung des Kraftstoffs. Lediglich die Differenz zwischen momentaner Bedarfsmenge und der sauggedrosselten Menge wird über ein Druckregelventil abgesteuert.The pump-integrated control devices can Flow rate of the gear pump from 100 l per hour to 1000 l per hour at a speed of 2 500 per minute can be set. By suction throttling achieved that the volume flow is not linear with the speed increases, but from a certain Pump speed is constant. In contrast to customizing the Flow rate is controlled by a pressure control valve less power "destroyed" with the suction throttle. The leads to less heating of the fuel. Only the difference between the current requirement quantity and the throttled crowd gets over one Pressure control valve shut off.
Durch die Verwendung des Übersetzungsgetriebes können große Fördermengen erzielt werden. Durch die Kombination des Übersetzungsgetriebes mit der Saugdrosselung wird eine Anpassung an ein Förderkennfeld möglich. By using the translation gear can be large Production rates can be achieved. By combining the Transmission gear with the suction throttling becomes one Adaptation to a funding map possible.
Durch das Übersetzungsgetriebe erhöht sich die Pumpendrehzahl beim Starten des Motors (Motordrehzahl ungefähr gleich 100 pro Minute). Bei einem direkten Antrieb über die Nockenwelle (Drehzahl gleich 50 pro Minute) würde die Zahnradpumpe infolge des schlechten Wirkungsgrades eventuell gar nicht ansaugen. Durch die höhere Pumpendrehzahl arbeiten auch die Gleitlager der Pumpe effizienter. Mischreibung durch zu geringe Drehzahlen kommt seltener vor.The transmission gear increases Pump speed when starting the engine (engine speed approximately equal to 100 per minute). With a direct drive over the camshaft (speed equal to 50 per minute) the gear pump due to poor efficiency possibly not suction at all. By the higher one Pump speed also work the slide bearings of the pump more efficient. Mixed friction comes from too low speeds less often.
Mit der erfindungsgemäßen Zahnradpumpe können unterschiedliche Flanschformen, unterschiedliche Deckel mit verschiedenen Anschlüssen, unterschiedliche Dichtelemente und /oder unterschiedliche Ventile kombiniert werden. Außerdem kann ein Vorreiniger oder ein elektrisches Notabschaltventil integriert werden.With the gear pump according to the invention different flange shapes, different lids with different connections, different sealing elements and / or different valves can be combined. It can also be a pre-cleaner or an electric one Emergency shutdown valve can be integrated.
