The invention further relates to a fuel injector assembly comprising a fuel injector, a fuel rail and a clip for connecting and positioning the fuel injector into the fuel rail. A clip of this kind is particularly suitable for use in a fuel supply device of an internal combustion engine.
- In order to keep pressure fluctuations during the operation of the internal combustion engine at a very low level, internal combustion engines are supplied with a fuel accumulator to which the injection valves are connected and which has a relatively large volume. Such a fuel accumulator is often referred to as a fuel rail.
- Known fuel rails comprise a hollow body with recesses in form of cups, where the fuel injection valves are arranged. The connection of the fuel injection valves to the fuel rail, that supplies the fuel from a fuel tank via a low or high pressure fuel pump, needs to be very precise to get a correct injection angle.
- The object of the invention is to create a clip which is simple and at the same time ensures a precise connection and position between a fuel injector and a fuel rail.
- It is furthermore the object of the invention to create a fuel injector assembly, that ensures a precise dosing of fuel.

The clip comprises a first recess being designed for retaining a fuel injector and a second recess that communicates with the first recess being designed for retaining an injector guide which is connected to the fuel injector. Further, the clip comprises a third recess being designed for retaining a cup guide of a cup of the fuel rail.
- Such a clip has the advantage of being able to achieve a narrower position of the fuel injector to the cup. This guarantees a more accurate angular positioning of the fuel injector in the fuel rail and furthermore, an optimum of the spray targeting point and the spraying angle. The clip can ensure a high quality connection between the fuel injector and the fuel rail. The function of the clip is on the one hand a anti-twist device and on the other hand a connecting function.

- In a further advantageous embodiment of the clip the third recess of the clip is arranged in an angular position to the second recess. The angular position of the third recess to the second recess has the advantage that the third recess can retain the cup guide of the cup of the fuel rail very easily.
- In a further advantageous embodiment of the clip the angle between the third recess and the second recess of the clip is about 90°. That is a very advantageous design for retaining the cup guide in the third recess.

- In a further advantageous embodiment of the clip, the clip is made out of stainless steel. The use of the clip being made out of stainless steel ensures a higher capacity of resistance to wear and corosion. Such a material is widely and fairly cheaply available.
- The invention is in accordance with the second aspect distinguished by a fuel injector assembly, comprising a fuel injector with a housing, a valve body, at least one nozzle, an injector guide and a connection area to a fuel rail. The fuel injector assembly further comprises a fuel rail having a cup with a cup guide and further comprises a clip in accordance with one of the preceding claims for connecting and positioning the fuel injector in the cup of the fuel rail. Such a fuel injector assembly has the advantage that the fuel injector is very precisely connected and positioned to the cup of the fuel rail.

- A fuel feed device is assigned to an internal combustion engine (Figure 1). It includes a
fuel tank 4 that is connected via a first fuel line to a pressure pump 5. The output end the pressure pump 5 is connected to an inlet of afuel rail 2. Fuel injectors 1 are actively connected to thefuel rail 2. The fuel is this fed to the fuel injectors 1 via thefuel rail 2. The fuel injectors 1 have a sealed connection to thefuel rail 2. - Figure 2 shows a fuel injector assembly, comprising a fuel injector 1, a
clip 15 and acup 3. The fuel injector 1 is arranged in the cup of thefuel rail 2 and connected and positioned to the cup by theclip 15. The fuel injector that is suitable for injecting a fuel into a gasoline engine or that also may be suitable for injecting fuel into a diesel engine, comprises a housing, a valve body, at least one nozzle, aninjector guide 13 and aconnection area 16 to the fuel rail. Theinjector guide 13 is arranged in theconnection area 16 of the fuel injector 1. Theinjector guide 13 comprises a guidance in form of a cap. Alternative embodiments of theinjector guide 13 are possible. Thecup 3 is connected to thefuel rail 2 and comprises acup guide 14 in form of a nose. The nose is, for example, embodied with a rectangular cross-section. Thecup guide 14 meshs in thethird recess 11 of theclip 15. - Figure 3 shows the clip of the fuel injector assembly in Figure 2. The
clip 15 further comprises a first recess 9 and asecond recess 10. The first recess is being designed for retaining the fuel injector 1. In a prefered embodiment the first recess 9 has the geometrical shape of the fuel injector 1 in the aera of the clip collet.

In other advantageous embodiments different designs of thethird recess 11 are possible. Furthermore, the first recess 9 and thesecond recess 10 are designed in a way that makes it possible to push the fuel injector in the first recess 9 by elastic deformation. This design has the advantage that the clip may be installed in a radial direction to the fuel injector.
The first recess 9 and thesecond recess 10 are in a prefered embodiment arranged in an angular position to the third recess. The angle between the third recess and the second recess is about 90°, but in other advantagous embodiments are angles of 0° up to 90° possible. - Figure 4 shows the top view of the clip shown in Figure 2 and Figure 3. Figure 5 shows the side view of the clip and the angle between the third recess and the second recess is about 90°.
