Definitions
- the invention relates to a fuel injection device according to the preamble of claim 1, such as from the document FR 2 776 025 A known.
- a fastening device for a fuel injection valve for attachment to a suction tube in which the axial fixation of the fuel injection valve on the fuel distributor line or on a plug-in nipple by a fastener, which is designed as a U-shaped securing clip provided with two resiliently resilient legs is.
- 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.
- each fastening measure leads, for example by a support collar to increase the radial extent of the fuel injection valve and thus to an increased space requirement during installation.
- 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 injection valve and fuel distributor surfaces of the sleeve serving as a holding down represent the production edges resulting from the production of the blank of the sleeve cutting edges.
- the fuel injection device with the characterizing features of claim 1 has the advantage that a direct and thus very accurate Vermosfix ist between fuel injector and connecting piece is created by simple measures on the fuel injector and the connecting piece.
- a pin-shaped raised pin is provided on the fuel injection valve, which corresponds to a groove-like depression or recess on the connecting piece of the fuel distribution line. The protruding into the recess pin of the fuel injector ensures regardless of the hold-down for a rotation of the fuel injection valve relative to the fuel rail and for a reliable assignment of the rotational position of the blank holder to the fuel injection valve.
- 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 Verwarfix ist the blank holder against the connection piece is eliminated by the pairing Spigot / recess on the fuel injector / connecting piece.
- 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.
- FIG. 1 a partially illustrated fuel injection device with a first hold-down in a side view
- FIG. 2 the fuel injection device according to FIG. 1 in a perspective view
- FIG. 3 A second embodiment of a fuel injection device in a perspective view

- the fuel injection valve 1 is part of a fuel injection device.
- the fuel injection valve 1 which is designed in the form of a direct-injection injector for injecting fuel directly into a combustion chamber of the internal combustion engine, is installed in a receiving bore of a cylinder head, not shown.
- a sealing ring 2, in particular of Teflon®, ensures optimum sealing of the fuel injection valve 1 with respect to the wall of the cylinder head.
- the valve receptacle can also be provided on a receiving socket of a suction pipe, not shown.
- the fuel injection valve 1 has at its inlet-side end 3 a plug connection to a fuel distributor line 4, which is represented by a sealing ring 5 between a connecting piece 6 of the fuel distributor line 4, which is shown in section, and an inlet connection 7 of Fuel injection valve 1 is sealed.
- the fuel injection valve 1 has an electrical connection plug 8 for the electrical contacting for actuating the fuel injection valve 1.
- a hold-down device 10 is provided according to the invention between the fuel injection valve 1 and the connecting piece 6.

- the hold-down 10 has a part-ring-shaped base element 11, wherein this base element 11, which does not rotate through 360 °, but for example has only an extension of about 250 ° to 320 °, is supported on a shoulder 12 of the fuel injection valve 1.
- axially resilient hold-down bracket 13 of the hold-down 10 abuts a downstream end surface 14 of the connecting piece 6 to the fuel rail 4 in the installed state.
- the hold-down 10 is interrupted, wherein the hold-down 10 forms a closed bracket element, in particular the FIGS. 2 to 4 clarify. In this way, the hold-down 10 can surround the fuel injector 1 and still allows the passage of the electrical connector plug 8.
- the hold-down bar 13 protrudes with its resilient brackets from the connector 8 away.
- a pin-shaped raised pin 15 is provided on the fuel injector 1, which corresponds to a groove-like depression or recess 16 at the connecting piece 6 of the fuel manifold 4.
- the projecting into the recess 16 pin 15 of the fuel injector 1 ensures a direct and thus very secure rotation of the fuel injector 1 relative to the fuel rail 4 and for a reliable assignment of the rotational position of the blank holder 10 to the fuel injector 1.
- the recess 16 on the connecting piece 6 of the fuel distributor line 4 extends from the end face 14 and extends in slot-like or groove-like manner in the axial direction.

- the basic elements 11 of the hold-down 10 of the FIGS. 5 and 6 upright, for example, in turn, with a wall thickness of about 1.5 mm, but thus also dictates the small width of the support surface of the respective base member 11 on the shoulder 12.
- the hold-down 10 represents a closed bracket member, since the hold-down bar 13 is connected endlessly to the base member 11. From the base member 11, two webs 21 extend with increased width largely in the axial direction and thus substantially perpendicular to the extension plane of the base member 11. These webs 21 go kinked into the actual axially resilient holddown 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.

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-BiegeTeil. 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.
