- the securing clip engages in the mounted state by corresponding recesses of the plug-in nipple and can be latched into a recess formed as an annular groove in a connecting piece of the fuel injection valve.
- the axial clearance between the recesses and the securing clip as well as between the annular groove and the securing clip should be kept small in order to achieve an exact fixation of the fuel injection valve without tension of the seal.
- a disadvantage of the DE 29 26 490 A1 known fastening device is in particular the bracing effect of the various mounting parts on the fuel injection valve.
- the force flow generated in the fuel injection valve leads to deformations and thus to changes in the stroke of the valve needle to jamming and to a pressure or bending load of the housing parts, which are generally thin-walled and welded together at several points.

- the fastening device comprises a sleeve which is clamped between a shoulder of the fuel rail and a shoulder of the fuel injection valve and is formed of an elastic material. Due to its tubular structure, the sleeve can transfer the hold-down forces to the fuel injector only to a limited extent effectively.
- the claimed by the shoulders of the fuel injector and fuel rail surfaces of serving as hold down sleeve represent the manufacturing edges resulting in the production of the blank of the sleeve cutting edges.

From the base member 11, two webs 21 extend with increased width largely in the axial direction and thus substantially perpendicular to the plane of extension of the base member 11. These webs 21 go kinked into the actual axially resilient hold-down bracket 13, wherein the hold-down bracket 13 composed of three essential sections.
- the hold-down bar 13 has, starting from the webs 21, only a small axial extent, which results from two uniform oblique sections 22.

Der erfindungsgemäße Niederhalter für eine Brennstoffeinspritzvorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, dass er eine besonders einfache Bauweise aufweist, sehr einfach und kostengünstig herstellbar ist und trotzdem eine sehr wirksame Niederhaltung eines Brennstoffeinspritzventils in einer Aufnahmebohrung eines Zylinderkopfes oder eines Ansaugrohres erzielbar ist. Mit herkömmlichen Fertigungsverfahren, wie Stanzen, Erodieren oder Laserschneiden lassen sich aus Blechen aus Federstahl bzw. Edelstahl Rohlinge für den späteren Niederhalter herauslösen und durch Biegen in zahlreiche, recht komplexe gewünschte Formen bringen.The hold-down device according to the invention for a fuel injection device with the characterizing features of
Mit dem erfindungsgemäßen Niederhalter ohne Mittel zur Verdrehfixierung ist eine genauere Ausrichtung des Brennstoffeinspritzventils gegenüber bekannten Niederhaltern mit integrierten Verdrehfixierungen möglich, da die Bauteiltoleranzen des Niederhalters für die Verdrehfixierung durch die erfindungsgemäße Ausgestaltung entfallen. Der Niederhalter kann zudem größere axiale Toleranzen ausgleichen, als dies mit bekannten Niederhaltern möglich ist. Vor allen Dingen in Verbindung mit der Brennstoffeinspritzvorrichtung, die eine einfache Verdrehfixierung aufweist, ergeben sich die oben angegebenen Vorteile.With the hold-down device according to the invention without means for Verdrehfixierung a more accurate alignment of the fuel injector over known holddowns with integrated Verdrehfixierungen is possible, since the component tolerances of the hold-down for Verdrehfixierung omitted by the inventive design. The hold-down device can also compensate for larger axial tolerances than is possible with known hold-downs. Especially in connection with the Fuel injection device having a simple Verdrehfixierung, the above-mentioned advantages.

Von Vorteil ist es, den Niederhalter als Stanz-Biege-Teil auszuführen und derart zu formen und in einer Brennstoffeinspritzvorrichtung zu verbauen, dass die durch Biegespannung beanspruchten Flächen der Schrägabschnitte und Anlageabschnitte des Niederhalters senkrecht zu den Schnittkanten verlaufen, die beim Herauslösen des Rohlings für den Niederhalter aus dem entsprechenden Blech entstehen. Auf diese Weise lässt sich die dauerhafte Belastbarkeit der auf Biegung beanspruchten Abschnitte des Niederhaltebügels des Niederhalters erhöhen und eine optimale Niederhaltekraft auf das Brennstoffeinspritzventil zur sicheren Fixierung in der Aufnahmebohrung erzielen.It is advantageous to carry out the hold-down as a stamped and bent part and shape and obstruct in a fuel injector that the stress of bending stress surfaces of the inclined portions and abutment portions of the blank perpendicular to the cutting edges, the release of the blank for the Hold-downs from the corresponding sheet arise. In this way, the permanent load capacity of the stressed portions of the hold-down bracket of the hold-down can be increased and achieve an optimum hold-down force on the fuel injection valve for secure fixation in the receiving bore.
Besonders vorteilhaft ist es, den Niederhalter in Umfangsrichtung gesehen derart mit einem offenen Bereich zu versehen, dass dieser von dem Anschlussstecker des Brennstoffeinspritzventils durchragt wird, so dass für den Niederhalter eine eindeutige Einbauposition definiert ist. Eine Verdrehfixierung des Niederhalters gegenüber dem Anschlussstutzen entfällt durch die Paarung Zapfen/Ausnehmung am Brennstoffeinspritzventil/Anschlussstutzen. Der Niederhalter ist dabei derart am Brennstoffeinspritzventil montiert, dass ein durch Biegespannung beanspruchter Niederhaltebügel vom Anschlussstecker des Brennstoffeinspritzventils weg gerichtet ist.It is particularly advantageous to provide the hold-down in the circumferential direction with an open area in such a way that it is penetrated by the connection plug of the fuel injection valve, so that a clear installation position is defined for the hold-down. A Verdrehfixierung the blank holder relative to the connection piece is eliminated by the mating pin / recess on the fuel injector / nozzle. The holding-down device is mounted on the fuel injection valve in such a way that a hold-down clip subjected to bending stress is directed away from the connection plug of the fuel injection valve.

Das Brennstoffeinspritzventil 1 weist an seinem zulaufseitigen Ende 3 eine Steckverbindung zu einer Brennstoffverteilerleitung 4 auf, die durch einen Dichtring 5 zwischen einem Anschlussstutzen 6 der Brennstoffverteilerleitung 4, der im Schnitt dargestellt ist, und einem Zulaufstutzen 7 des Brennstoffeinspritzventils 1 abgedichtet ist. Das Brennstoffeinspritzventil 1 verfügt über einen elektrischen Anschlussstecker 8 für die elektrische Kontaktierung zur Betätigung des Brennstoffeinspritzventils 1.The
Um das Brennstoffeinspritzventil 1 und die Brennstoffverteilerleitung 4 radialkraftfrei voneinander zu beabstanden und das Brennstoffeinspritzventil 1 sicher in der Aufnahmebohrung des Zylinderkopfes oder Ansaugrohrs niederzuhalten, ist erfindungsgemäß ein Niederhalter 10 zwischen dem Brennstoffeinspritzventil 1 und dem Anschlussstutzen 6 vorgesehen. Der Niederhalter 10 ist als bügelförmiges Bauteil ausgeführt, z.B. als Stanz-Biege-Teil. Der Niederhalter 10 weist ein teilringförmiges Grundelement 11 auf, wobei sich dieses Grundelement 11, das nicht um 360° umläuft, sondern z.B. nur eine Erstreckung von ca. 250° bis 320° besitzt, an einer Schulter 12 des Brennstoffeinspritzventils 1 abstützt.

Der in die Ausnehmung 16 ragende Zapfen 15 des Brennstoffeinspritzventils 1 sorgt für eine direkte und damit sehr sichere Verdrehsicherung des Brennstoffeinspritzventils 1 gegenüber der Brennstoffverteilerleitung 4 und für eine sichere Zuordnung der Drehlage des Niederhalters 10 zum Brennstoffeinspritzventil 1. Andererseits ist mit dem Niederhalter 10 eine genauere Ausrichtung des Brennstoffeinspritzventils 1 gegenüber bekannten Niederhaltern mit integrierten Verdrehfixierungen möglich, da die Bauteiltoleranzen des Niederhalters 10 für die Verdrehfixierung durch die neue Ausgestaltung entfallen.
