Definitions
- the invention relates to a fuel injector according to the preamble of the main claim.
- a fuel injector is already known in which a fuel filter is made in one piece with a retaining collar.
- the retaining collar extends radially beyond the fuel inlet connector and has a nose outside the fuel inlet connector.
- the circumferential nose of the retaining collar forms, together with a groove on the outer circumference of the fuel inlet connection, a snap-in connection, through which the fuel filter is fastened in a defined manner.
- a filter for a fuel injection valve with a central fuel supply which is in a form-fitting connection with an adjusting sleeve for a return spring which keeps the fuel injection valve closed in the idle state.
- the filter consists of a plastic frame over which a mesh is placed.
- the filter is connected to the adjustment sleeve, which is preferably made of metal, by means of a snap lock.
- a disadvantage of the fuel injection valves known from the above-mentioned documents is, in particular, the high production expenditure which is incurred for fixing the filter either on the adjusting sleeve or on the fuel inlet connection. Furthermore, the filter and the adjustment sleeve are made of different materials, with chip removal and abrasion occurring mainly on the plastic of the filter, which can lead to malfunctions of the fuel injector due to the deposition of the particles.
- the fuel injector according to the invention with the characterizing features of the main claim has the advantage that the sleeve for adjusting the dynamic flow is integrally formed with the filter element 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 quick and inexpensive manufacture and Assembly is made possible.
- the combined filter sleeve is manufactured inexpensively by deep drawing, so that on a plastic frame with a filter grid attached to it can be dispensed with.
- Flow openings are preferably provided, which can be introduced quickly and precisely into the filter sleeve in large numbers by laser drilling.
- Another advantage is that the filter sleeve can also be removed if necessary.
- Fig. 1 shows a schematic section through an embodiment of a fuel injector designed according to the invention
- FIG. 2 shows an excerpted schematic section through the exemplary embodiment shown in FIG. 1 in area II in FIG. 1.
- a fuel injector 1 is e.g. B. in the form of an injection valve for fuel injection systems of spark-ignited, mixture-compressing internal combustion engines executed.
- the fuel injection valve 1 shown is suitable for injecting fuel directly into a combustion chamber (not shown) of an internal combustion engine.
- the invention is equally suitable for fuel injection valves 1 for injecting fuel into an intake manifold of the internal combustion engine.
- the fuel injector 1 consists of a nozzle body 2, in which a valve needle 3 is guided.
- the valve needle 3 is operatively connected to a valve closing body 4, which cooperates with a valve seat surface 6 arranged on a valve seat body 5 to form a sealing seat.
- fuel injector 1 is a fuel injector 1 that opens inward and has a spray opening 7.
- the nozzle body 2 is sealed by a seal 8 against an outer pole 9 of a solenoid 10.
- the magnet coil 10 is encapsulated in a coil housing 11 and wound on a coil carrier 12, which bears against an inner pole 13 of the magnet coil 10.
- the inner pole 13 and the outer pole 9 are separated from one another by a gap 26 and are supported on a connecting component 29.
- the magnet coil 10 is excited via a line 19 by an electrical current that can be supplied via an electrical plug contact 17.
- the plug contact 17 is surrounded by a plastic sheath 18, which can be molded onto the inner pole 13.
- valve needle 3 is guided in a valve needle guide 14, which is disc-shaped.
- a paired adjusting disk 15 is used for stroke adjustment.
- An armature 20 is located on the other side of the adjusting disk 15. This armature is non-positively connected via a flange 21 to the valve needle 3, which is connected to the flange 21 by a weld seam 22.
- a restoring spring 23 is supported on the flange 21, which in the present design of the fuel injector 1 is supported by a sleeve 24 Bias is brought.
- the sleeve 24, which is designed as an adjusting sleeve, is designed in one piece with a filter element 25 according to the invention.
- the component formed in this way is referred to below as filter sleeve 34.
- the filter effect arises through flow openings 35, which are introduced into an inflow end 36 of the filter sleeve 34.
- An outflow end 37 of the filter sleeve 34 is shaped in such a way that it can be used to adjust the spring preload of the return spring 23 and thus to adjust the static flow rate through the fuel injector 1.
- a detailed description of the filter sleeve 34 can be found in the description of FIG. 2.
- Fuel channels 30a to 30c run in the valve needle guide 14, in the armature 20 and on the valve seat body 5, which channels the fuel, which is supplied via a central fuel supply 16, to the spray opening 7.
- the fuel injector 1 is sealed by a seal 28 against a receiving bore, not shown, for. B. sealed in a fuel rail.
- the armature 20 In the idle state of the fuel injection valve 1, the armature 20 is acted upon by the return spring 23 against its stroke direction in such a way that the valve closing body 4 is held in sealing contact with the valve seat 6.
- the magnet coil 10 When the magnet coil 10 is excited, it builds up a magnetic field which moves the armature 20 against the spring force of the return spring 23 in the stroke direction, the stroke being predetermined by a working gap 27 which is in the rest position between the inner pole 13 and the armature 20.
- the armature 20 also carries the flange 21, which is welded to the valve needle 3, in the lifting direction.
- the valve closing body 4, which is operatively connected to the valve needle 3, lifts off the valve seat surface and fuel is sprayed off via the spray opening 7.
- the armature 20 falls after the magnetic field has been sufficiently reduced by the pressure of the Return spring 23 from the inner pole 13, whereby the flange 21 which is operatively connected to the valve needle 3 moves against the stroke direction.
- the valve needle 3 is thereby moved in the same direction, as a result of which the valve-closure member 4 is seated on the valve seat surface 6 and the fuel injection valve 1 is closed.
- FIG. 2 shows an excerpted sectional view of the detail of the fuel injector 1 designed according to the invention, designated II in FIG. 1.
- the filter sleeve 34 is constructed in such a way that the throughflow openings 35 are formed at the inlet-side end 36, while the outflow-side end 37 is sleeve-shaped, so that the prestressing of the return spring 23 by inserting the filter sleeve 34 into the fuel injection valve 1 is changeable.
- the filter sleeve 34 is preferably formed from metal in order to ensure a permanent clamping effect during the entire service life of the fuel injector 1. It is manufactured by deep drawing, a manufacturing process that is simple and inexpensive.
- small-caliber flow openings 35 are introduced in large numbers into the inlet end 36 of the filter sleeve 34. This is preferably done by laser drilling, since extremely fine, small-volume bores can be produced here.
- the diameter of the flow openings 35 is preferably 0.04 to 0.05 mm, as a result of which dirt particles in the fuel can be filtered out to a satisfactory degree.
- the number of flow openings 35 depends on the available area of the filter area 25.
- the filter sleeve 34 can be extended or the area of an inlet-side cover plate 38 can be used Filter sleeve 34, the number of flow openings 35 can be increased.
- the interior of the fuel injection valve 1 can be protected twice against contamination which can lead to malfunctions during the operation of the fuel injection valve 1.
- the dynamic flow is adjusted by moving the filter sleeve 34 with the filter 25 already installed, so that contaminations of the adjusting tool cannot get into the valve interior.
- machining and abrasion are eliminated when filter 25 is pressed in at the end of the production line, which also prevents malfunctions due to deposition of the abrasion or larger particles.
- the setting of the dynamic flow through the fuel injection valve 1 can also be carried out more easily and quickly by the combined filter sleeve 34.
- the filter sleeve 34 projects so far upstream into the central fuel supply 16 that it can be moved more easily or even removed again in an emergency.
- the filter sleeve 34 is arranged considerably closer to the valve group after the flow has been set, so that the surface between the filter sleeve 34 and the valve group also becomes smaller and the risk of contamination thus decreases.
- the invention is not limited to the illustrated embodiments and suitable for any construction of fuel injection valves 1, for. B. for fuel injectors 1 for manifold injection or for fuel injectors 1 with connection to a common rail system.
