Definitions
- the invention relates to a fuel injector according to the preamble of the main claim.
- a fuel injector with a seal arranged on the spray side is known.
- the seal which is made, for example, of a copper-tin alloy or stainless steel, is arranged in an annular groove radially encircling a nozzle body and is axially positively fixed in this way, sealing the fuel injector against a cylinder head.
- a disadvantage of the fuel injector known from the abovementioned publication is, in particular, that the seal cannot be arranged as close as desired to the transition to the combustion chamber due to the completely positive embedding of the seal. Gases or fuel in the combustion chamber can penetrate into the gap between the injection-side end of the fuel injector and the cylinder head and lead to leaks in the seal, for example by lifting the seal from the annular groove or unburned Fuel settles in the gap, which can have a negative impact on the exhaust gas.
- the fuel injector according to the invention with the characterizing features of the main claim has the advantage that the seal can be performed up to the transition to the combustion chamber and the sealing effect is improved.
- the seal is advantageously joined by welding, laser welding, caulking or pressing in the area of the fuel injector on the spray-side side.
- the joint can thus be manufactured inexpensively and reliably according to the requirements.
- the seal consists of a metal, in particular steel or V2A steel, a copper alloy and / or a brass alloy. Depending on the requirements for temperature resistance and temperature behavior, the seal can be designed accordingly advantageously and inexpensively.
- the seal has the shape of a sleeve or the seal is produced by reshaping, in particular deep drawing and / or flanging.
- the seal can thus be produced very inexpensively and very accurately in large quantities.
- the first section is advantageously at least partially permanently elastic and is therefore biased against the valve receiving opening.
- the seal can, for example, after removing the Fuel injector can be reused when installing the same fuel injector and can remain on the fuel injector.
- the sealing effect of the seal can be improved by the first section protruding outward from the adjacent parts of the seal and / or the first section being designed in a wave shape and thereby abutting the valve receiving opening at several points.
- the seal can also be produced more easily by a U-shaped design of the seal.
- the bottom of the U-shaped section is also advantageous to arrange the bottom of the U-shaped section at the level of one step, as a result of which the dead space located between the nozzle body and the valve receiving opening is minimized, or to be arranged at the level of the end of the diameter indentation remote from the spray, as a result of which the first section is caused by the gas pressure in the combustion chamber is pressed against the valve receiving opening and the sealing effect is thereby improved.
- the seal advantageously extends axially between the spray-side region of the fuel injection valve and the valve receiving opening up to a transition at which the valve receiving opening merges into the combustion chamber. This also minimizes dead space.
- the first section lies at least partially in a sealing manner on a diagonally tapering first contact surface that narrows the diameter of the valve receiving opening. This can improve the sealing effect of the seal, and this can also be achieved in that the seal is biased indirectly against other parts of the fuel injector against at least the first contact surface.

- the magnetic coil 10 is excited via an electrical 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.

- 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 surface 6.
- the magnetic coil 10 When the magnetic 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 12 and the armature 20.
- the armature 20 also takes the first flange 21, which is welded to the valve needle 3, in the lifting direction.
- the valve closing body 4 connected to the valve needle 3 lifts off the valve seat surface 6, and the fuel supplied under pressure is sprayed through the spray opening 7 into the combustion chamber (not shown).
- 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, as a result of which the first flange 21, which is connected to the valve needle 3, moves counter to 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 injector 1 is closed.
