    • The invention relates to a fuel injection device for internal combustion engines. Said fuel injection device comprises a plurality of fuel injection valves (10) that are supplied with fuel by a high-pressure fuel accumulator (24). Every fuel injection valve (10) has a needle-shaped injection valve member (15) whose movement is controlled via the fuel pressure that prevails in a control chamber (35). According to the invention, the movement of the valve member (70) that relieves the control chamber (35) to a relief chamber (39) and that is coupled to a tappet (57) is controlled by means of two piezo actuators (45, 65). The piezo actuators (45, 65) are mounted in series so that their travel has the same effective direction.
