Abstract (en)

[origin: EP0745764A2] A control device (15) regulates the adjustment movement of the injection valve component. It has a longitudinally displaceable control piston (30), which is activated by the fuel system pressure from the high pressure feed conduit (40,41) and also by the fuel control pressure in a control chamber (60). The control chamber is connected via first control aperture with the high pressure feed conduit (40). The control pressure in the control chamber is controllable by the opening or closing of at least one second control aperture. For the control device, an electrically controllable operating component (5) is provided.
