Definitions

  • the invention relates to a fuel injection valve according to the preamble of the main claim.
  • a fuel injector in which a fuel filter is press-fitted into the fuel inlet port at the upstream end of the fuel injector.
  • This fuel filter is provided at the periphery, for example, with a brass ring which forms the mating with the wall of the Brennscherinlassstutzens when pressing the fuel filter.
  • the brass ring surrounds an annular solid plastic section of the main body of the fuel filter, from which extend, for example, three webs in the longitudinal direction to a common bottom portion, of which the actual screen mesh is encapsulated in these sub-areas.
  • An adjusting sleeve downstream of the fuel filter is used to adjust the spring bias of a voltage applied to the adjusting return spring.
  • the fuel injection valve according to the invention with the features of the main claim has the advantage that a setting element is used as a combined component in the fuel inlet that combines a high functional integration (adjustment of the spring force of the return spring, filtering the fuel, damping of pressure pulsations) in itself, the adjustment of a Sleeve is formed to the outside, which receives two inserts in their interior and encloses them safely and protected.
  • the filter element is brought from a metal fabric by deep drawing in a dome or dome contour, which is very precisely in the sleeve of the adjusting element can be fitted.

  • FIGS. 2 to 5 Embodiments of a fuel injection valve according to the invention will be described in more detail, is to better understand the invention first with reference to FIG. 1 an already known fuel injection valve will be briefly explained with respect to its essential components.
  • fuel injection valve 1 is designed in the form of a fuel injection valve 1 for fuel injection systems of mixture-compression, spark-ignition internal combustion engines.
  • the fuel injection valve 1 is suitable in particular for the direct injection of fuel into a combustion chamber, not shown, of an internal combustion engine.
  • the fuel injection valve 1 consists of a nozzle body 2, in which a valve needle 3 is arranged.
  • the valve needle 3 is operatively connected to a valve closing body 4 which cooperates with a valve seat body 6 arranged on a valve seat body 5 to form a sealing seat.
  • the fuel injection valve 1 in the exemplary embodiment is an inwardly opening fuel injection valve 1, which has at least one injection opening 7.
  • the nozzle body 2 is sealed by a seal 8 against an outer pole 9 of a magnetic coil 10.

  • the plug contact 17 is surrounded by a plastic casing 18, which may be molded on
  • valve needle 3 is guided in a valve needle guide 14, which is designed disk-shaped. Upstream of the dial 15 is an armature 20. This is a non-positively connected via a first flange 21 with the valve needle 3 in connection, which is connected by a weld 22 with the first flange 21. On the first flange 21 is supported Return spring 23 from which is brought in the present design of the fuel injection valve 1 by an adjusting sleeve 24 to bias.
  • Fuel channels 30, 31 and 32 extend in the upper valve needle guide 14, in the armature 20 and on a lower guide element 36.
  • the fuel is supplied via a central fuel supply 16 and filtered by a filter element 25.
  • the fuel injection valve 1 is sealed by a seal 28 against a fuel distributor line, not shown, and by a further seal 37 against a cylinder head, not shown.
  • a Vorhubfeder 38 is arranged, which holds the armature 20 in the resting state of the fuel injection valve 1 in abutment against the second flange 34.
  • the spring constant of the Vorhubfeder 38 is substantially smaller than the spring constant of the return spring 23rd
  • the armature 20 In the idle state of the fuel injection valve 1, the armature 20 is acted upon by the return spring 23 and the Vorhubfeder 38 against its stroke direction so that the valve closing body 4 is held on the valve seat surface 6 in sealing engagement. Upon excitation of the magnetic coil 10, this builds up a magnetic field, which initially moves the armature 20 counter to the spring force of the prestroke spring 38 in the stroke direction, wherein an anchor free travel is predetermined by the distance between the first flange 21 and the armature 20. After passing through the armature free passage, the armature 20 takes the first flange 21, which is welded to the valve needle 3, against the spring force of the return spring 23 also in the stroke direction with.
  • the armature 20 passes through a total stroke, which corresponds to the height of the working gap 27 between the armature 20 and the inner pole 13.
  • the valve closing body 4 communicating with the valve needle 3 lifts off from the valve seat surface 6, and the fuel guided via the fuel channels 30 to 32 is sprayed through the injection opening 7.
  • the armature 20 drops after sufficient degradation of the magnetic field by the pressure of the return spring 23 from the inner pole 13, whereby the valve connected to the needle 3 in communication first flange 21 moves against the stroke direction.
  • the valve needle 3 is thereby moved in the same direction, whereby the valve closing body 4 touches on the valve seat surface 6 and the fuel injection valve 1 is closed.
  • the Vorhubfeder 38 then acts on the armature 20 again so that it does not rebound from the second flange 34, but returns to the rest state without Anschlagspreller.
  • the inner pole 13 is made sleeve-shaped towards the inlet end of the fuel injection valve 1 and thus forms a connecting sleeve 40 in this area.
  • the connecting sleeve 40 can also be formed as a separate component independently of the inner pole 13, into which then e.g. the inner pole 13 is fitted.
  • the filter element 25 is introduced, which serves to filter out such particles in the fuel, which could otherwise lead to functional impairments of the relevant valve components such as the sealing seat.
  • the electromagnetic circuit may e.g. be replaced by a piezoelectric actuator or a magnetostrictive actuator as an actuator.

  • the throttle bore 54 has, for example, a diameter of 0, 4 mm to 1.5 mm, depending on the opening width of the connecting sleeve 40.
