Abstract

The fuel injector, particularly common rail injector has an injection valve element (7) adjustable in axial direction between a closing position and a releasing position opened in the fuel current into the combustion chamber. A squeezing gap (31) is limited on a side of a valve needle (17) opposite to an anchor (19).
