Abstract (en)
[origin: DE19624001A1] In a fuel injection device for internal combustion engines, a fuel injection valve has a plunger (21) which actuates an injection valve member and which delimits a control chamber (25) which is constantly supplied with high pressure fuel through a choke (27) and which can be discharged through a control valve (36) and an outflow channel (129). The control valve (36) has for that purpose a valve member (44) actuated by a piezoelectric element (35) in such a way that the valve member is moved towards the control chamber (25) when the outflow channel (129) is opened. In the closed position, the valve member (44) is pushed in the closing direction by the pressure in the control chamber (25).
