Abstract

The invention relates to a fuel injection device for internal combustion engines, preferably Diesel engines. The device has at least one control valve by means of which a control piston is displaceable by a pressure medium in order to convey fuel through at least one channel toward a combustion chamber of the internal combustion engine. The device has at least one accumulator for the pressure medium disposed in a flow direction of the pressure medium, whereby the accumulator is provided within the control piston.
