Definitions

  • the adjusting sleeve 48 is usually so in the central Recess 46 of the fuel injection valve 1 is pressed, that in their entire length of, for example, 8 mm the wall 47 of the central recess 46 of the core. 2 is applied. This is disadvantageous in so far as a to Pressing the adjusting sleeve 48 required assembly tool at the slightest deviation from the longitudinal axis 10 of the Fuel injection valve 1 Abspanungen on the wall 47th causes and this leaks or malfunction by the deposition of the chips in the Fuel injector 1 can cause.
