Patent ID: 7185635

Claim:
A fuel injection system for internal combustion engines comprising a high-pressure accumulator ( 15 ) that is acted on with highly pressurized fuel by a high-pressure delivery unit ( 8 ), and which supplies fuel to fuel injectors ( 19 ), a pressure control valve ( 57 ), which is disposed between a high-pressure side ( 33 ) and a low-pressure side ( 50 , 51 ), an electrical actuator ( 46 ) operable to actuate the pressure control valve ( 57 ) to actuate a valve element ( 47 ), wherein the pressure control valve ( 57 ) has an end surface ( 53 ) which is positioned within the high-pressure accumulator and, along with a wall of the high-pressure accumulator delimits a low-pressure chamber ( 51 , 52 ) within the high-pressure accumulator ( 15 ), the low-pressure chamber being sealed by means of a sealing location ( 54 ) which is disposed on the low-pressure side.
