  • Fuel injection device for an internal combustion engine
    Patent number: 7143955
    Abstract: A fuel injection apparatus having at least one solenoid valve for controlling the fuel injection that is contained in a housing part and a solenoid assembly having a magnetic coil and a magnet armature inserted into a recess of the housing part. A cover piece that can be attached to the housing part fixes the solenoid assembly in the housing part. A spring element is disposed between the cover piece and the solenoid assembly and clamps the solenoid assembly in the housing part. At least one securing element is formed onto the spring element and is of one piece with it, which secures the spring element to the housing part and secures the solenoid assembly in the recess of the housing part without the cover piece being attached to the housing part.
