Abstract (en)
[origin: DE10123994A1] The device has an electrically controlled valve that controls the connection of the pump's working chamber to a relief chamber and a second valve that controls the connection of a fuel injection valve control pressure chamber and the pump's working chamber. The valves are controlled by a common actuator that controls pressure in an actuator pressure chamber. Both control valves have a valve element subjected to actuator pressure chamber pressure. The device has a fuel pump (10) per engine cylinder forming a unit with a fuel injection valve (12). An electrically controlled valve (60) controls the connection of the pump's working chamber to a relief chamber and a second valve (70) controls the connection of a control pressure chamber in the fuel injection valve and the pump's working chamber. The valves are controlled by a common actuator (64) that controls the pressure in an actuator pressure chamber. Both control valves have a valve element subjected to the pressure in the actuator pressure chamber.
