Abstract
The invention relates to a fuel injection device for an internal combustion engine, having a common high-pressure collection chamber (common rail) that can be filled via a high-pressure pump. The high-pressure collection chamber communicates with injection valves, each of which includes a control valve embodied as a 3/2-way valve. Control faces are provided on the control part, which connect a high-pressure collection supply line to inflow lines to the injection nozzle or with a relief line, and the control part is actuatable by a controlled outflow line. The control part includes a throttle element, which via a bore communicates with a hollow chamber.
