Fuel injection device for internal combustion engines

摘要

A fuel injection device for internal combustion engines having a high pressure accumulation chamber, which can be filled by a high pressure fuel pump and from which high pressure lines lead to the individual injection valves. Control valves for controlling the high pressure injection at the injection valves, as well as an additional pressure storage chamber between these control valves and the high pressure accumulation chamber are inserted in the individual high pressure lines. In order to be able to carry out a shaping of the course of injection at the injection valve, the control valve has a hydraulic throttle segment disposed at an additional collar on the valve member as well as a damping chamber formed between the collar and a flat valve seat, whose throttled relief delays the opening motion of the valve member at the onset of injection.
