Definitions
- the invention relates to a kit of parts with extension part for an injection valve for a combustion engine and with a base injector part, to an injection valve for a combustion engine and to a fuel delivery assembly.
- Injection valves are in widespread use, in particular for internal combustion engines where they may be arranged in order to dose fluid into an intake manifold of the internal combustion engine or directly into the combustion chamber of a cylinder of the internal combustion engine.
- the respective injection valve may be suited to dose fluids under very high pressures.
- the pressures may be in the range of up to 200 bar and in the case of a diesel engine in the range of up to 2 000 bar, for example.
- Injection valves are manufactured in various forms in order to satisfy the various needs of the various combustion engines. Therefore, for example, their length, their diameter, and also various elements of the injection valve responsible for the way the fluid is dosed, may vary in a wide range. For instance, injection valves for installing on a cylinder head in a central position require a greater length compared to a standard injector size, e. g. of about 90 mm.
- US 2005/211225 A1 relates to a mounting structure for mounting an injector to an internal combustion engine with a fixing member which is inserted into a hole of a cylinder head in an axial direction. Thus, the injector is fixed between the fixing member and the cylinder head. Fuel is also supplied to the injector through the fixing member.
- US 6, 318, 341 B1 discloses a fuel injection system which is used for direct injection of fuel into the combustion chambers of an internal combustion engine.
- This fuel injection system has at least one fuel injector which has a fuel inlet orifice.
- a fuel distributor line having for each fuel injector a fuel outlet orifice connectable to the fuel inlet orifice of the fuel injector.
- the fuel inlet orifices of the fuel injectors can be connected to a corresponding fuel outlet orifice by a tubular adapter.
- a similar fuel injection system is disclosed in EP 1780403 A2 as a prior art device.
- DE 10115048 A1 relates to a connecting part for connecting a fuel line to a fuel injection valve which has a first connecting piece that can be inserted into a locating hole in the fuel line and a second connecting piece which can be inserted in a recess in the fuel injection valve.
- kit of parts having the features of claim 1.
- Advantageous embodiments of the kit of parts, the injection valve and the fuel rail assembly are given in the sub-claims.
- a kit of parts comprising the extension part and the base injector part is specified.
- the extension part and the base injector part may be provided for being assembled to form the injection valve.
- a fuel delivery assembly comprising the injection valve and a fuel rail cup are specified.
- the fuel rail cup is in particular provided for hydraulically coupling the injection valve to a fuel rail of the fuel delivery assembly.
- the extension part comprises a first fluid inlet portion with a first sealing section and a fluid outlet portion.
- the first fluid inlet portion of the extension part is in particular designed to be coupled to the fuel rail cup in a given first coupling area.
- the first fluid inlet portion is constructed in such fashion that a detachable mechanical connection may be formed with the fuel rail cup.
- the first fluid inlet portion is designed to be coupled to the fuel rail cup in the first coupling area in such a way that the first sealing section of the first fluid inlet portion is coupled in a force-fitting manner with the fluid rail cup.

- the fluid outlet portion of the extension part is in particular designed to be coupled to the second fluid inlet portion in a second coupling area in a force-fitting manner.
- the second fluid inlet portion of the base injector part is preferably coupled to the fluid outlet portion of the extension part in such a way that the second sealing section of the second fluid inlet portion is coupled in a given second coupling area with the fluid outlet portion of the extension part in a force-fitting manner.
- the extension part is constructed to be mechanically connected to the base injector part in detachable fashion, in particular by means of the - preferably force-fitting - coupling in the second coupling area. In this way, particularly easy and cost-effective assembly and inspection of the injection valve is possible.
- the base injector part comprises the functionality of a complete injection valve.
- it comprises a valve body having an injection nozzle, a valve needle in the valve body for controlling fuel flow through the injection nozzle and an actuator assembly for driving the valve needle.
- the base injector part may comprise at least one external electrical terminal, for example for connecting the actuator assembly.
- the base injector part may be assembled on the same assembly and testing equipment as an injection valve comprising a standard length. This enables a higher standardization for injection valves for different applications. A similar injection valve design can be used for injection valves requiring different lengths. Furthermore, this enables a cost-effective manufacturing of the injection valves because of lower manufacturing and testing equipment costs.
- the coupling is flexible.
- the extension part has a first longitudinal axis and the base injector part has a second longitudinal axis.
- the first and second longitudinal axes may be tiltable with respect to each other by means of the flexible mechanical coupling.
- this flexible connection enables to recover misalignments between the fuel rail cup and an injector pocket without, or minimally, introducing mechanical stress on components of the injection valve.
- a firmly bonded coupling nor a form-fitting coupling is necessary for the coupling of the extension part with the base injector part.
- the injector pocket may be arranged in a cylinder head of the combustion engine. It is in particular provided for receiving the injection valve.

- the extension part comprises a second recess being arranged and designed for taking at least one electrical connection in such a way that the at least one electrical terminal of the base injector part can be electrically accessed via the electrical connection from the outside of the extension part. In this way an electrical interlinkage between the base injector part and the extension part can be obtained.
- the second recess may be arranged at least partly parallel to the first recess. For example, it is radially offset with respect to the central longitudinal axis L.
- the extension part may comprise a further electrical terminal partly arranged in the second recess, preferably in a first end area of the extension part on an fluid inlet side of the extension part.
- the electrical connection e. g. a wire
- the at least one electrical connection, and in this regard the at least one electrical terminal, is easily accessible.
- the further electrical terminal of the extension part may comprise at least two different types of connectors for different customer applications. In this way installation of the injection valve may be further facilitated.
- the second fluid inlet portion of the base injector part comprises identical geometric dimensions as the first fluid inlet portion of the extension part in such a way that the second fluid inlet portion is designed to be coupled to the fuel rail cup.
- the fluid outlet portion of the extension part is shaped in such fashion that the - preferably force-fit - coupling in the second coupling area can be established with a base injector part the second fluid inlet portion of which basically has the type and dimensions of the first fluid inlet portion of the extension part. This supports a cost-effective manufacturing of the injection valve.

- the base injector part comprises a first connector element and the extension part comprises a corresponding second connector element and the first connector element and the corresponding second connector element are designed and arranged for coupling the base injector part and the extension part for mounting and/or handling purposes.
