Kraftstoffverbindungsrohr für ein Kraftstoffeinspritzventil

A fuel injector (10) for discharging fuel to an internal combustion engine is disclosed. The injector includes a nozzle body (12) having a solenoid actuator (18), a pole piece (50) with an axial extending fuel passage (188), a valve assembly (16) including a reciprocably moveable armature operable against the bias of a spring member a calibration tube extending through the pole piece fuel passage and operable to load the spring, an axially extending, drawn metal fuel tube (74) having a first end defining an injector fuel inlet (76) and a second end (84) in communication with the axially extending fuel passage of the pole piece. The fuel tube (74) includes features (180,92) which extend radially inwardly in the wall of the fuel tube (74) to define depressions in the outer surface of the wall which function, with an overmolded composite jacket (54) to deter rotation of the tube. Additionally, the features defining radial inward projections from the inner surface of said wall and may be used to position the filter assembly (94) and to align externally installed components of the injector.
