Abstract
A fuel injection system for internal combustion engines includes a high-pressure accumulator acted on with highly pressurized fuel by a high-pressure delivery unit and in turn supplies fuel to fuel injectors. The fuel injection system has a pressure control valve, which is disposed between a high-pressure side and a low-pressure side and actuating a valve element. The pressure control valve is actuated by means of an electrical actuator. An end surface of the pressure control valve delimits the low-pressure region in the high-pressure accumulator and is sealed by means of a seal disposed on the low-pressure side.
