After the production the adjusting sleeve, the filter fabric in a further step in be suitably fastened to the adjusting sleeve. In use of the Fuel injection valve there is a risk that the filter fabric back from the Can release the adjusting sleeve.
  • the fuel injection valve according to the invention with the characterizing features of the main claim has In contrast, the advantage that the sleeve for adjusting the dynamic flow integral with the filter element is formed and thus on the one hand, the position of the sleeve is easily adjustable by the outstanding filter element and on the other hand a fast and inexpensive Production and assembly is possible.
  • the combined filter sleeve is doing by deep drawing manufactured inexpensively, so that on a plastic frame dispensed with an attached filter grid can.
  • flow openings are provided which through Laser drilling in large numbers quickly and accurately in the Filter sleeve can be introduced.
  • the filter sleeve if the Need exists, can also be removed again.
  • a fuel injection valve 1 is z. B. in the form of a Injector for fuel injection systems of spark-ignited, mixture-compressing internal combustion engines executed.
  • the illustrated fuel injection valve 1 suitable for direct injection of fuel into one not shown combustion chamber of an internal combustion engine.
  • the Invention is also in fuel injection valves. 1 for injecting fuel into a suction pipe of Internal combustion engine in the same way suitable.

  • the fuel injection valve 1 acts it is in the exemplary embodiment to an inwardly opening Fuel injection valve 1, which via a Spray opening 7 has.
  • the nozzle body 2 is through a Seal 8 against an outer pole 9 of a magnetic coil 10th sealed.
  • the magnetic coil 10 is in a coil housing 11 encapsulated and wound on a bobbin 12, which rests against an inner pole 13 of the magnetic coil 10. Of the Inner pole 13 and the outer pole 9 are through a gap 26th separated and based on one Connecting component 29 from.
  • the magnetic coil 10 is connected via a Line 19 of a via an electrical plug contact 17th energized electric current.
  • the plug contact 17 is surrounded by a plastic sheath 18, the Inner pole 13 may be molded.
  • the valve needle 3 is in a valve needle guide fourteenth guided, which is designed disk-shaped.
  • Stroke adjustment is a paired shim 15.
  • An the other side of the dial 15 is a Anchor 20. This is frictionally connected via a flange 21 with the valve needle 3 in conjunction, by a Weld 22 is connected to the flange 21.
  • a return spring 23 is supported, which in the present design of the Fuel injection valve 1 by a sleeve 24 Bias is brought.
  • the as adjusting sleeve trained sleeve 24 is inventively integral with a filter element 25 is formed.

  • the fuel injection valve 1 is through a Seal 28 against a not shown Receiving bore, z. B. in a fuel rail, sealed.
  • the armature 20 drops sufficient reduction of the magnetic field by the pressure of the Return spring 23 from the inner pole 13, causing the with the valve needle 3 operatively connected flange 21st moved against the stroke direction.
  • the valve needle 3 is thereby moved in the same direction, causing the Valve closing body 4 touches on the valve seat surface 6 and the fuel injection valve 1 is closed.
  • Fig. 2 shows in an excerpted sectional view of the in Fig. 1 with II designated detail of the invention designed fuel injection valve. 1
  • the filter sleeve 34 is so constructed that at the inlet end 36, the Through openings 35 are formed, while the downstream end 37 is sleeve-shaped, so that the bias of the return spring 23 by the insertion the filter sleeve 34 in the fuel injection valve. 1 is changeable.
  • the filter sleeve 34 is preferably made of metal Molded to a permanent clamping effect during the entire life of the fuel injection valve 1 to guarantee.
  • the production is done by deep drawing, a Manufacturing process that is simple and inexpensive.
  • the diameter the flow-through openings 35 is preferably 0.04 to 0.05 mm, whereby dirt particles in the fuel in can be filtered satisfactorily.
  • the number the flow openings 35 depends on the available area of the filter area 25. For example can by an extension of the filter sleeve 34 or through Utilization of the surface of an inlet-side cover plate 38 of the Filter sleeve 34 increases the number of flow openings 35 become.
