Definitions
- the invention relates to a fuel injector according to the preamble of claim 1.
- an electromagnetically actuated fuel injection valve in which an armature interacts with an electrically excitable solenoid for electromagnetic actuation and the stroke of the armature is transmitted to a valve closing body via a valve needle.
- the valve closing body interacts with a valve seat.
- the armature is not rigidly attached to the valve needle, but is arranged to be axially movable relative to the valve needle.
- a first return spring acts on the valve needle in the closing direction and thus keeps the fuel injector closed when the solenoid is de-energized and not energized.
- the armature is acted upon in the stroke direction by means of a second return spring such that the armature in the rest position rests against a first stop provided on the valve needle.
- a disadvantage of the fuel injector known from DE-OS 33 14 899 is, in particular, the complicated design, which provides for several individual components for the upper and the lower anchor stop. As a result, the manufacturing tolerances of the individual components add up to an overall tolerance, which has a disadvantageous effect on the switching precision of the fuel injector.
- the fuel injector according to the invention with the characterizing features of the main claim has the advantage that one of the armature stops, which define the size of a forward stroke gap for an armature free path construction, is formed in one piece with the valve needle, as a result of which accuracy in manufacturing processes has less of an impact due to the saving of at least one component ,
- the armature stop arranged on the outflow side of the armature is formed in one piece with the valve needle and forms a collar against which the armature rests.
- the size of the pre-stroke gap can be adjusted by moving the driving flange in the valve needle.
- a pre-lift spring acts on the armature in the idle state of the fuel injector, so that it is held in contact on the outflow-side armature stop.
- the fuel flowing through the fuel injection valve can be passed directly through the valve needle to the flow openings and to the sealing seat without diversions.
- Another advantage is the formation of a guide area on the driver flange, which ensures precise guidance of the valve needle during its axial movement.
- Fig. 1 shows a schematic section through an embodiment of a fuel injector designed according to the invention.
- a fuel injector 1 is in the form of a fuel injector for fuel injection systems of mixed compression, spark-ignited
- the Fuel injection valve 1 is particularly suitable for injecting fuel directly into a combustion chamber (not shown) of an internal combustion engine.
- the fuel injector 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 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 preferably connected by welding to an outer pole 9 of a magnet coil 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 performed in the present embodiment, thin-walled hollow cylinder and has a central recess 8.
- Flow-through openings 14, which are introduced into the wall of the valve needle 3, serve for the fuel line to the sealing seat.
- the valve needle 3 has at its inflow-side end a collar-shaped anchor stop 32 which is formed in one piece with the valve needle 3.
- An anchor 20 is supported on the anchor stop 32. This is non-positively connected to the valve needle 3 via a driver flange 21.
- the driver flange 21 is also tubular and extends through the armature 20 through a central recess 33. The driver flange 21 is inserted into the inflow end of the valve needle 3 and through a weld 15 is connected to the valve needle 3.
- a restoring spring 23 is supported on the driving flange 21, which in the present design of the fuel injection valve 1 is preloaded by a sleeve 24.
- the return spring 23 acts on the valve needle 3 via the driving flange 21 so that the valve closing body 4 is held in sealing contact with the valve seat surface 6.
- the driver flange 21 has an outer circumferential surface, which supports the valve needle 3 during its axial movement when actuating the fuel injector 1 as a guide area such that center offsets and subsequent malfunctions of the fuel injector 1 can be avoided by a tilted or jammed valve needle 3. Downstream of the projection 34, the driver flange 21 has a guide section 36 which serves to guide the armature 20.
- a pre-lift spring 22 is arranged which acts on the armature 20 in such a way that it is held in contact with the armature stop 32.
- the fuel which is supplied via a central fuel supply 16 and filtered by a filter element 25, is passed through the recess 8 of the valve needle 3, a through opening 37 in the driving flange 21 and through the throughflow openings 14 to the spray opening 7.
- the fuel injector 1 is sealed by a seal 28 against a distribution line, not shown.
- the driver flange 21 inserted into the valve needle 3 is acted upon by the return spring 23 against its stroke direction in such a way that the valve closing body 4 on the valve seat 6 is held in sealing contact.
- the armature 20 rests on the armature stop 32 when acted upon by the pre-lifting spring 22.
- the magnetic coil 10 When the magnetic coil 10 is excited, it is installed Magnetic field, which moves the armature 20 against the spring force of the preliminary stroke spring 22 and the return spring 23 in the stroke direction.
- the stroke of the armature 20 is divided into a preliminary stroke, which serves to close a preliminary stroke gap 30, and an opening stroke.
- the axial height of the forward stroke gap 30 is defined by a shoulder 35 of the driver flange 21 facing the armature 20, which is undercut by the armature 20 after the forward stroke gap 30 is closed, as a result of which the frictional connection for actuating the valve needle 3 is achieved.
- the armature 20 After passing through the forward stroke against the force of the preliminary stroke spring 22, the armature 20 takes the driving flange 21, which is welded to the valve needle 3, and thereby the valve needle 3 in the stroke direction.
- the valve closing body 4, which is operatively connected to the valve needle 3, lifts off from the valve seat surface 6, as a result of which the fuel which is led via the recess 8 in the valve needle 3 and through the throughflow openings 14 to the spray opening 7 is sprayed off.
- the armature 20 drops from the inner pole 13 after the magnetic field has been sufficiently reduced by the “pressure of the return spring 23 on the driving flange 21, as a result of which the valve needle 3 moves counter to the stroke direction.
- the valve closing body 4 rests on the valve seat surface 6 and the fuel injection valve 1 is closed.
- the anchor 20 touches the anchor stop 32.
- the pre-lift spring 22 has a damping effect against bouncing of the armature 20 on the armature stop 32 when the fuel injector 1 closes. If the armature 20 is in contact with the armature stop 32, the armature 20 can be lifted briefly from the armature stop 32 again come. The prestroke spring 22 brakes the resulting motion of the armature "20 from in the lifting direction, so that the driving flange 21 and thus also the valve needle 3 remain unaffected by the movement of the armature 20 and no undesirable, short-term opening operations of the fuel injection valve 1 occur.
- the invention is not restricted to the exemplary embodiments shown and can also be used for other forms of anchors 20, for example for submersible and flat anchors, as well as any construction of fuel injection valves 1.
