Abstract
A fuel injection valve for intermittent fuel injection into a combustion space of a combustion engine comprises an injection valve indirectly actuated electromagnetically by a hydraulic amplifier. The opening motion of the injection valve element remains limited at low and medium injection pressure, while the opening motion of the injection valve element is substantially more rapid and the opening path of the injection valve element substantially larger at high injection pressure than it is at low to medium injection pressure. It is possible to operate the engine over the complete load and rotational speed range under optimum injection conditions.
