Abstract
Known fuel injectors have a valve housing in which an actuator and an hydraulic coupler are arranged, an electrical plug being provided on the valve housing for contact with a voltage source. The cables running from the plug to the actuator must be guided around the coupler to the actuator. It is disadvantageous that the compensating movements put heavy mechanical stress on the cables, so that a cable fracture as a result of material fatigue occurs after a predefined service life of the fuel injector, or that the solder or welding points of the cables tear. This leads to malfunctioning of the fuel injector. In the present fuel injector, the service life is increased by the provision of connections without cables. The earth pole of the actuator is electrically connected to the ground terminal of the plug in a cable-less manner, and the positive pole of the actuator is electrically connected to the positive terminal in a cable-less manner.
