Beschreibung der AusführungsbeispieleDescription of the embodiments

In Figur 1 ist ein Teil eines Kraftstoffinjektors 1 mit einem Injektorgehäuse 2 im Längsschnitt dargestellt. Der in Figur 1 sichtbare Teil des Injektorgehäuses 2 wird auch als Haltekörper 3 bezeichnet. Der Haltekörper 3 weist in Figur 1 unten ein abgeschnittenes Ende 4 auf, das dem (nicht dargestellten) Brennraum einer Brennkraftmaschine zugewandt ist. Deshalb wird das abgeschnittene Ende 4 auch als brennraumnahes Ende bezeichnet. In Figur 1 oben weist das Injektorgehäuse 2 beziehungsweise der Haltekörper 3 ein brennraumfernes Ende 5 auf. Das Injektorgehäuse 2 erstreckt sich zwischen dem brennraumnahen Ende 4 und dem brennraumfernen Ende 5 entlang einer Längsachse 6.FIG. 1 shows a part of a fuel injector 1 with an injector housing 2 in longitudinal section. The visible in Figure 1 part of the injector 2 is also referred to as a holding body 3. The holding body 3 has in Figure 1 below a cut end 4, which faces the (not shown) combustion chamber of an internal combustion engine. Therefore, the cut end 4 is also referred to as near the combustion chamber end. In FIG. 1 above, the injector housing 2 or the holding body 3 has an end 5 remote from the combustion chamber. The injector housing 2 extends between the end 4 close to the combustion chamber and the end 5 remote from the combustion chamber, along a longitudinal axis 6.

In dem Injektorgehäuse 2 ist mindestens ein Kraftstoffkanal 8 vorgesehen, welcher der Zufuhr und/oder Abfuhr von Kraftstoff dient. Der Kraftstoffkanal 8 mündet an seinem brennraumfernen Ende in eine trichterförmige Vertiefung 10, die sich nach außen hin konisch erweitert. Die Vertiefung 10 ist durch einen Ringkörper 12 am brennraumfernen Ende 5 des Injektorgehäuses 2 eingefasst. Radial außerhalb und konzentrisch zu dem Ringkörper 12 erstreckt sich eine Schweißverbindungsnaht 14, durch die ein Flansch 15 einer Klemmeinrichtung 16 stoffschlüssig mit dem Injektorgehäuse 2 verbunden ist.In the injector 2 at least one fuel passage 8 is provided, which serves for the supply and / or discharge of fuel. The fuel channel 8 opens at its end remote from the combustion chamber into a funnel-shaped depression 10, which widens conically towards the outside. The recess 10 is bordered by an annular body 12 at the combustion chamber remote end 5 of the injector housing 2. Radially outside and concentric with the ring body 12 extends a weld joint 14 through which a flange 15 of a clamping device 16 is integrally connected to the injector housing 2.

Die Klemmeinrichtung 16 umfasst einen Klemmstutzen 17 mit einem Grundkörper 18, der einstückig mit dem Flansch 15 verbunden ist. Der Grundkörper 18 hat im Wesentlichen die Gestalt eines Kreiszylindermantels, dessen brennraumnahes Ende stoffschlüssig mit dem Flansch 15 verbunden ist. Das brennraumferne Ende 19 des Grundkörpers 18 ist offen ausgebildet. Der Klemmstutzen 17 weist eine Ausnehmung 20 auf, durch die sich ein Winkelstutzen 22 hindurch erstreckt.The clamping device 16 comprises a clamping sleeve 17 with a base body 18 which is integrally connected to the flange 15. The main body 18 has substantially the shape of a circular cylinder jacket whose combustion chamber near the end is cohesively connected to the flange 15. The combustion chamber remote end 19 of the base body 18 is open. The clamping sleeve 17 has a recess 20, through which an elbow 22 extends therethrough.

Der Winkelstutzen 22 weist ein Leitungsanschlussende 23 mit einem Außengewinde auf, das zum Anschließen einer Kraftstoffleitung dient. Der Winkelstutzen 22 weist des Weiteren ein Injektoranschlussende 24 auf, das senkrecht zu dem Leitungsanschlussende 23 angeordnet ist. Der Winkel zwischen den Enden 23, 24 kann aber auch mehr oder weniger als 90 Grad betragen. Das Injektoranschlussende 24 ist mit einem Dichtkegel ausgestattet, der komplementär zu der Vertiefung 10 in dem brennraumnahen Ende des Injektorgehäuses 2 ausgebildet ist.The elbow 22 has a pipe end 23 with an external thread, which serves to connect a fuel line. The elbow 22 further includes an injector port end 24 which is disposed perpendicular to the conduit port end 23. The angle between the ends 23, 24 may also be more or less than 90 degrees. The injector connection end 24 is equipped with a sealing cone, which is formed complementary to the recess 10 in the combustion chamber near the end of the injector housing 2.

Das Injektoranschlussende 24 liegt mit seinem Dichtkegel unter Dichtwirkung an der Vertiefung 10 an. Zusätzlich liegt der Winkelstutzen 22 auf einem Aufnahmelager 28 auf, das im Bereich der Ausnehmung 20 an dem Klemmstutzen 17 vorgesehen ist. An der dem Brennraum abgewandten Seite des Winkelstutzens 22 liegt ein Einstellstück 29 an, das mit Hilfe eines Schraubelements 30 zum Brennraum hin, also in Figur 1 nach unten, mit einer Klemmkraft beaufschlagt ist. Die von dem Schraubelement 30 über das Einstellstück 29 auf den Winkelstutzen 22 aufgebrachte Klemmkraft bewirkt, dass der Dichtkegel mit dem Injektoranschlussende 24 in dichter Anlage in der Vertiefung 10 gehalten wird. Durch das Aufnahmelager 28 in Kombination mit dem Einstellstück 29 wird eine stabile Befestigung des Winkelstutzens 22 gewährleistet.The injector connection end 24 rests with its sealing cone under sealing effect on the recess 10. In addition, the angle piece 22 is located on a receiving bearing 28 which is provided in the region of the recess 20 on the clamping piece 17. At the side facing away from the combustion chamber of the elbow 22 is an adjusting piece 29, which is acted upon by means of a screw 30 towards the combustion chamber, ie in Figure 1 down, with a clamping force. The force exerted by the screw 30 on the adjusting piece 29 on the elbow 22 clamping force causes the sealing cone is held with the Injektoranschlussende 24 in close contact with the recess 10. By the receiving bearing 28 in combination with the adjusting piece 29 a stable attachment of the angle piece 22 is ensured.

Der Haltekörper 3 und der Klemmstutzen 17 sind jeweils aus einem schweißfähigen Material gebildet. Der dargestellte Kraftstoffinjektor hat den Vorteil, dass das Injektorgehäuse 2 nach der Fertigung und vor dem Anschweißen des Klemmstutzens 17 genauso geprüft werden kann wie bei herkömmlichen Kraftstoffinjektoren mit einem Anschlussstutzen, der sich nach oben, das heißt vom Brennraum weg, erstreckt. Des Weiteren kann die Fertigung des Injektorgehäuses 2 genauso erfolgen wie bei herkömmlichen Kraftstoffinjektoren. Das Anschweißen des Klemmstutzens 17 erfolgt vorzugsweise erst nach der Fertigung und Prüfung des Injektorgehäuses 2. Der Klemmstutzen dient nach dem Anschweißen zur Aufnahme des Winkelstutzens 22, der dann unter Zwischenschaltung des Einstellstücks 29 mit Hilfe des Schraubelements 30 unter Dichtwirkung an dem brennraumfernen Ende des Injektorgehäuses 2 festgeklemmt wird. Die Lage des Winkelstutzens 22 ist in Umfangsrichtung um die Längsachse 6 des Injektors 1 frei wählbar.The holding body 3 and the clamping piece 17 are each formed of a weldable material. The illustrated fuel injector has the advantage that the injector housing 2 can be tested in the same way as in the case of conventional fuel injectors with a connecting piece which extends upwards, that is to say away from the combustion chamber, after manufacture and prior to welding on the clamping piece 17. Furthermore, the manufacture of the injector housing 2 can be carried out in exactly the same way as with conventional fuel injectors. The welding of the clamping piece 17 is preferably carried out after the manufacture and testing of the injector 2. The clamp is used after welding for receiving the elbow 22, which then with the interposition of the adjusting piece 29 by means of the screw 30 under sealing effect at the combustion chamber remote end of the injector. 2 is clamped. The position of the elbow 22 is freely selectable in the circumferential direction about the longitudinal axis 6 of the injector 1.

In den Figuren 2 und 3 ist eine ähnliche Darstellung wie in Figur 1 in verschiedenen Ansichten gezeigt. Zur Bezeichnung gleicher Teile werden die gleichen Bezugszeichen verwendet. Um Wiederholungen zu vermeiden, wird auf die vorangegangene Beschreibung der Figur 1 verwiesen. Im Folgenden wird hauptsächlich auf die Unterschiede zwischen den beiden Ausführungsbeispielen eingegangen.FIGS. 2 and 3 show a similar representation as in FIG. 1 in different views. To denote the same parts, the same reference numerals are used. To avoid repetition, reference is made to the preceding description of FIG. In the following, the differences between the two embodiments are mainly discussed.

Bei dem in den Figuren 2 und 3 dargestellten Ausführungsbeispiel weist der Klemmstutzen 17 eine Ausnehmung 41 in Form eines Durchgangslochs auf.In the embodiment shown in Figures 2 and 3, the clamping piece 17 has a recess 41 in the form of a through hole.

Der Winkelstutzen 22 erstreckt sich durch das Durchgangsloch 41 hindurch. In Figur 3 sieht man, dass das Auflager 28 in einer halbkreisförmigen Vertiefung eines Ringkörpers 45 ausgebildet ist. Der Ringkörper 45 ist einstückig mit dem Injektorgehäuse 2 verbunden. Innerhalb des Ringkörpers 45 ist ein Sackloch 44 ausgebildet. Im Zentrum des Sacklochs 44 ist die Vertiefung 10 mit der Durchtrittsöffnung angeordnet.The elbow 22 extends through the through hole 41 therethrough. In Figure 3 it can be seen that the support 28 is formed in a semicircular recess of an annular body 45. The annular body 45 is integrally connected to the injector housing 2. Within the annular body 45, a blind hole 44 is formed. In the center of the blind hole 44, the recess 10 is arranged with the passage opening.

In den Figuren 4 und 5 ist die Befestigung eines Winkelstutzens 52 an einem Haltekörper 3 gemäß einem weiteren Ausführungsbeispiel dargestellt.
