  • Patent number: 7017840
    Abstract: An injection device for injecting fuel comprises a nozzle needle (2), which is arranged in a nozzle body (1), and a micro-bore (10) formed in the nozzle body (1), in which at least one injection hole (8) is configured. Here one tip (3) of the nozzle needle (2) projects into the micro-bore (10) in such a way that the tip (3) is arranged at the level of the injection holes (8) in the axial direction (X—X) of the nozzle needle, with recesses being formed in the tip at the tip (3) of the nozzle needle (2) level with the injection holes (8), in order to ensure a minimum distance between the tip (3) and the injection holes (8).
    Type: Grant

  • Patent number: 6086348
    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.
