Abstract (en)

[origin: EP1236884A2] Fuel injection device for an internal combustion engine comprises a first electrically operated control valve (60) controlling at least indirectly a connection of the pump working chamber (22) with a discharge chamber (24), and a second electrically operated control valve (70) controlling the pressure in a pressure chamber (52) of the fuel injection valve (12) which impinges on the injection valve element (28) at least indirectly in the closing direction. The two control valves are arranged on the fuel injection valve. Preferred Features: The lead (14) leads into a valve body (26) of the fuel injection valve and branches into a line (54) leading into a pressure chamber (40) surrounding the injection valve element and into a line (55) leading to the control valves.
