Abstract

Durch die Erfindung wird eine Kraftstoffzuführvorrichtung mit einer Einspritzeinrichtung geschaffen, bei der bei gleichbleibender Querschnittsfläche im Vergleich zu einer bekannten kreisförmigen Querschnittsfläche (15) einer Querbohrung in einem Common Rail (17) durch Streckung der Querschnittsfläche in Umfangsrichtung (M) und Stauchung in Längsrichtung (B) der Längsbohrung (18) in dem Common Rail (17) eine Querbohrung mit einer elliptischen oder schlitzförmigen Querschnittsfläche (15, 16) geschaffen wird. Alternativ oder zusätzlich zu dieser Maßnahme ist die Querbohrung von der äußeren Mantelfläche des Common Rails (17) in Richtung zu der Längsbohrung (18) derart aufgeweitet, dass die Bohrungsverschneidung der Querbohrung zu der Längsbohrung (18) in Umfangsrichtung vergrößert wird.

Figure 00000001
The invention provides a fuel supply device with an injection device, in which, with a constant cross-sectional area compared to a known circular cross-sectional area (15), a transverse bore in a common rail (17) by stretching the cross-sectional area in the circumferential direction (M) and compression in the longitudinal direction (B ) of the longitudinal bore (18) in the common rail (17), a transverse bore with an elliptical or slot-shaped cross-sectional area (15, 16) is created. As an alternative or in addition to this measure, the transverse bore is widened from the outer lateral surface of the common rail (17) in the direction of the longitudinal bore (18) in such a way that the intersection of the holes in the transverse bore with the longitudinal bore (18) is increased in the circumferential direction.
