Abstract (en)
[origin: EP1411238A1] The pressure-limiting valve (56) has a pressure side coupled to the high pressure region of the fuel injection system and a valve element (74) biased against a valve seat (72) and providing a hydraulic connection between an inlet and an outlet dependent on the pressure difference between them. The outlet of the pressure-limiting valve is coupled to the feed space (60) of a high pressure pump for the fuel injection system. An Independent claim for a fuel injection system for an IC engine is also included.
