- the spray perforated disc 21 has at least one, for example, four ejection openings 27 formed by erosion, laser drilling or punching.
- the insertion depth of the core 2 in the injection valve is decisive for the stroke of the valve needle 14.
- the one end position of the valve needle 14 is fixed in the non-energized magnetic coil 1 by the contact of the valve closing body 19 on the valve seat surface 16 of the valve seat body 15, while the other End position of the valve needle 14 results in energized solenoid coil 1 by the system of the anchor portion 17 at the downstream end of the core.
- the stroke is adjusted by an axial displacement of the core 2, for example, produced by a machining process such as turning, which is subsequently connected firmly to the valve sleeve 6 according to the desired position.

- a fuel filter 32 is disposed above the adjusting sleeve 29 in the valve sleeve 6.
- the injector described so far is characterized by its particularly compact design, so that a very small, handy injection valve is created.

- the largely executed as a plastic part connector 40 therefore has a serving as a fuel inlet nozzle tubular body 42.
- a concentric to the valve longitudinal axis 10 extending flow bore 43 of an inner connecting pipe 44 in the base body 42 serves as a fuel inlet and is flowed through from the inflow end of the fuel injection valve in the axial direction of the fuel ,
- a hydraulic connection of connecting part 40 and functional part 30 is achieved in the fully assembled fuel injection valve in that the flow holes 43 and 28 of both modules are brought to each other so that an unimpeded flow through the fuel is ensured.
- a lower end 47 of the connecting tube 44 protrudes into the opening 11 of the valve sleeve 6 in order to increase the stability of the connection.
- the main body 42 made of plastic can be sprayed onto the functional part 30 so that the plastic immediately surrounds parts of the valve sleeve 6 and of the valve jacket 5.
- a secure seal between the functional part 30 and the main body 42 of the connecting part 40 is achieved, for example, via a labyrinth seal 46 on the circumference of the valve jacket 5.

- the components valve sleeve 6 and connecting pipe 44 which should be emphasized that the illustrated and described inventive measures are adequately transferable to all pressing areas of two metallic components in the fuel injector.
- press fits between the two components to be fastened are appropriate.
- press fits generally lead to compressions or strains of a plastic or elastic nature in the components, depending on the tolerance position, material and component geometry. Due to their rigidity, the component partners can not stretch or compress, or they are too soft in their material, eg soft magnetic chromium steels, it is very likely to cold welds ("eaters") during the joining process of the pressing.
- the installation conditions of the component partners If the press connection, for example, in the installed state subjected to an internal pressure, so this can lead to strains and widening. Again, there is a risk of loosening the press connection and in the worst case of loosening the connection. To prevent this, therefore, the largest possible pressure should be generated, which in turn increases the tendency of the components to cold welding.
- costly, precise and costly machining processes such as fine grinding or honing, the tolerances can be narrowed and press joints improved.
- the aim is to produce as cost-effective components that are provided as turned parts, press connections between metallic component partners that hold securely and reliably over a long period of time while avoiding cold welding and tight.
- the press connections should be made very simple and inexpensive, which is why a separate operation of coating or oiling or heating of the component partners is omitted for shrinking.
- FIG. 2 an example of a thin-walled valve sleeve 6 is shown, which extends over a large part of the axial length of the fuel injection valve and in which the connecting pipe 44 ( FIG. 3 ) in a region a and the core 2 can be pressed in a region b and to which the valve jacket 5 can be pressed in a region c.
- the connecting pipe 44 correspondingly has an outer pressing area a ', which corresponds to the area a in the installed state in the valve sleeve 6 to a press connection.
- a and a ' are characterized areas that come in principle for a material contact in the press connection in question; however, it does not have to span the entire length of a and a ' the press connection come about, as based on the FIGS. 4 to 8 will be explained.
- the connecting pipe 44 should be installed in the valve sleeve 6 with the lowest possible insertion force.
- inlet fillets 59 in the transition of the pressing area a 'to the axially following on both sides sections are inventively modified before.
- FIG. 4 shows a detailed view of a connecting pipe 44 before a profiling according to the invention. It becomes clear that the pressing area a 'on the connection pipe 44 is subdivided into three zones.
- the zone I is characterized by a Ein Industriesfase 50, which is designed either as obliquely inclined or slightly curved performed annular circumferential material reduction. This Ein Industriesfase 50 serves the safe, centered and spanverhindernden introduction of the component to be pressed component 6, 44 into each other.
- Zone II is followed by zone II, which forms the actual cylindrical pressing section 51.
- This cylindrical pressing section 51 is followed on the side opposite the insertion chamfer 50 by a zone III which, like the insertion chamfer 50, is withdrawn and defines a welding region 52.
- the welding region 52 extends at an angle ⁇ obliquely inclined back from the outer surface of the cylindrical pressing portion 51. The angle ⁇ is about 1 ° to 5 °.
- FIG. 5 shows a detailed view of an alternative connection pipe 44 before profiling according to the invention.
- the zone III is set back abruptly relative to the zone II serving as pressing section 51 via a shoulder 53, so that the outer jacket surface of the welding region 52 with a smaller outside diameter runs predominantly parallel to the outer circumferential surface of the cylindrical pressing section 51.
- connection pipe 44 in the valve sleeve 6 this profiling of the pressing area a ' is a very effective measure to avoid the unwanted effect described above.
- the two components 6, 44 are additionally secured and sealed against one another by means of a material-bonding joining method, such as welding or laser welding, then the profiling in the pressing region a 'may not be fully effective.
- the welding depth in the welding area 52 Eg, about 0.8 to 1.2 mm.
- a variable tread depth of the groove-like grooves 61 in the zones I, II, III of the pressing area a ' is provided, whereby a low-pore welding is made possible.
- FIG. 6 is a detailed view of a connecting tube 44 shown with a first profiling according to the invention.
- set back welding area 52 (zone III) is the lowest profile depth.
- the profile depth of the grooves 61 in the pressing section 51 (zone II) may correspond to that of zone II or be slightly larger.
- the zone I with the chamfer 50 has the area of grooves 61 which have the largest profile depth.
- FIG. 7 shows a section of the view according to FIG. 6 with an unavoidable disturbing paragraph 55 or any other erratic increase.
- groove-like grooves 61 are not shown to scale with their profile depths, but are clearly oversubscribed for a better understanding of the invention.
- FIG. 8 is a detailed view of a connecting pipe 44 with a second profiling according to the invention in a mounting situation in a valve sleeve 6 is shown.
- the middle cylindrical pressing section 51 is subdivided into two subzones IIa and IIb. While the grooves 61 of the first partial zone IIa still have the same profile depth as the grooves 61 of the lead-in chamfer 50, the grooves 61 of the partial zone IIb of the pressing section 51 have fewer deep grooves 61 whose low profile depth then extends as far as the welding area 52 continues.
