ABSTRACT:
A fuel injection system for internal combustion engines having a fuel injection valve communicating with a high-pressure source includes a control valve, which has a valve body with a longitudinally displaceably guided control piston. The control piston is guided in a bush, which is surrounded at least partly inside the valve body by an annular chamber, which communicates with the high-pressure source.
