Abstract

A fuel injection pump for internal combustion engines which has an integrated feed pump with an outer ring and an inner ring, the latter being coupled to a drive shaft of the fuel injection pump via a toothing. The individual teeth of this toothing extend with their respective end face and tooth bottom along a respective circular arc about a center point, which is located in the radial plane of the drive shaft extending through these teeth along the axis of the drive shaft. As a result, an increased angular offset between the drive shaft and the plane of the inner ring without the risk of wear is possible.
