Abstract

The fuel injector has nozzle needle (21), a coupling rod (40), which is partly surrounded by an annular space, which forms an internal storage space (36) for the fuel. The guide element (20) has a flange-like base plate (61) with a formed guide bush (62), which is guided in the axially adjustable coupling rod with the coupling piston (41).
