Abstract
The invention relates to a fuel injection device for internal combustion engines. A high-pressure reservoir (common rail) can be made to communicate with an injection nozzle via a 3/2-way valve having has a control valve member which connects a supply line to a high-pressure line or to a relief line discharging into a tank. On its end regions, opposite the stops, the control valve member is provided with elements 7, 21; 6, 22 that damp the stroke of the control valve member.
