Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Pumpenflansch in einen inneren und einen äußeren Teil unterteilt ist, wobei der innere Teil die Lagerstelle der Pumpennockenwelle und der äußere Teil Elemente des Niederdruckkreislaufes aufnimmt. Durch diese Maßnahme kann der innere Teil des Pumpenflansches als rotationssymmetrisches Bauteil hergestellt werden, während der äußere Teil den Begebenheiten und Anschlüssen des Pumpengehäuses sowie der Brennkraftmaschine angepasst werden kann. Durch die rotationssymmetrische Ausführung des inneren Teils kann eine höhere Präzision bei derAccording to the invention, this object is achieved in that the pump flange is divided into an inner and an outer part, wherein the inner part of the bearing of the Pump camshaft and the outer part of elements of the low pressure circuit absorbs. By this measure, the inner part of the pump flange can be made as a rotationally symmetric component, while the outer part of the events and connections of the pump housing and the internal combustion engine can be adjusted.

Dies hat den Vorteil, dass der Aufwand bei der Montage der beiden Teile des Pumpenflansches an dem Pumpengehäuse wesentlich reduziert wird. In einer weiteren Ausgestaltung der Erfindung verfügt der äußere Teil zur Führung an einer dem inneren Teil zugewandten Stirnseite über einen Steg. Vorteilhaft ist hierbei, dass sich diese Art der Führung mit niedrigem Herstellungsaufwand realisieren lässt.In a further development of the invention, the outer part is guided over the inner part of the pump flange. This has the advantage that the cost of mounting the two parts of the pump flange is substantially reduced to the pump housing. In a further embodiment of the invention, the outer part has to guide on a the inner part facing end side via a web. The advantage here is that this type of leadership can be realized with low production costs.
