Abstract

An electrically controlled fuel injector unit for fuel injection in internal combustion engines, in which an injection pump, an injection nozzle, and between them a control valve and control magnet are fastened in a fuel injector unit housing. The control valve and the control magnet, including requisite conduits, are combined in a magnet valve housing to form a structural unit that is inserted as a whole into the fuel injector unit housing. The control valve and control magnet are disposed eccentrically in the magnet valve housing, and a high-pressure conduit that connects the pump work chamber to the injection nozzle extends on a side of the magnet valve housing having a greater accumulation of material resulting from the eccentricity.
