Abstract
A fuel injection system having a high-pressure pump and a fuel injection valve for each cylinder of the engine in which the pump has a work chamber, and the fuel injection valve has a valve member movable in an opening direction counter to the force of a closing spring braced between the injection valve member and a displaceable storage piston that is acted upon, on its side remote from the closing spring, by the pressure in the pump work chamber. The storage piston is movable into a storage chamber counter to the force of the closing spring and the deflection stroke motion of the storage piston is limited by a stop. A shaft part having one portion of smaller cross section disposed in an outset position in a connecting bore and one portion of larger cross section disposed outside the connecting bore in the storage chamber, is movable with the storage piston, and upon the deflection stroke motion of the storage piston into the storage chamber, the shaft portion of larger cross section dips into the connecting bore.
