Abstract (en)
[origin: WO2004048769A1] The invention relates to a fuel injection device (1) for internal combustion engines, comprising a control valve (6) arranged between a high and a low pressure sides (5, 7), said control valve opening or blocking the connection of a control chamber (2) to the low pressure side (7). Said device also comprises a discharge throttle (8) arranged between the control valve (6) and the low pressure side (7). The control valve (6) has a first position in which the connection of the control chamber (2) to the low pressure side (7) is blocked, a second position in which the control chamber (2) is connected to the low pressure side (7) by means of a first discharge channel (14) and a third position in which the control chamber (2) is connected to the low pressure side (7) by means of a second discharge channel (16) having a discharge throttle (15).
