Abstract (en)

[origin: US2009199820A1] The invention relates to a fuel injection system for internal combustion engines, having a high-pressure accumulator which has a cavity under system pressure. Provided to the high-pressure accumulator is a pressure control valve that can be actuated electromagnetically. The cavity can be connected by the latter to a low-pressure side of the high-pressure accumulator. Arranged between the cavity and the low-pressure side of the high-pressure accumulator is a check valve which enables the high-pressure accumulator to be filled from the low-pressure side to the system pressure side.
