Patent ID: 8322629

Claim:
A fuel injector for injecting fuel into a combustion chamber of an internal combustion engine, the fuel injector comprising: an injector body; at least one electrically triggerable valve let into the injector body and having at least one electrical valve contact; at least one electrical injector body contact accessible from an outside of the injector body; at least one conductor conduit which has a rectilinear course; at least one solid electrical conductor at least in part connecting the at least one electrical valve contact and the at least one electrical injector body contact, the solid electrical conductor being substantially dimensionally stable under its own weight and extending through the at least one conductor conduit; and an electrically conductive connection joining the at least one solid conductor and the at least one electrical valve contact and/or via at least one electrically conductive connecting element joining the at least one electrically conductive connecting element to the at least one solid conductor and the at least one electrical valve contact via a respective electrically conductive connection each, wherein the electrically conductive connecting element includes a region of plastically deformable electrically conductive tongues or plastically deformable electrically conductive sawteeth, wherein the fuel injector is capable of being disassembled without destruction and assembled from at least two modules, and wherein said at least one electrical injector body contact is disposed on or in a first module, at least one electrically triggerable valve is disposed in a second module that is different from the first module, and wherein the at least one solid conductor is directly or indirectly reversibly and electrically conductively joined to the at least one injector body contact, and further comprising at least one third module having the at least one conductor conduit disposed therein, the third module being disposed substantially entirely between the first module and second module in series along an injector axis of the fuel injector such that the first module is disposed at a first axial end of the injector body and the second module is disposed at a second axial end of the injector body, with all the modules capable of being disassembled from all of the other modules and reassembled without destroying the fuel injector, and wherein the at least one solid conductor extends through the at least one conductor conduit along the rectilinear course, and the conductor conduit has different angles of inclination relative to the injector axis in each different third module of the fuel injector through which the conductor conduit extends.
