  "textContent": "Fuel injection system for internal combustion engines with a fuel injection valve (1) that has a housing in which a valve member (60) is arranged to move axially in a bore (62). The valve member (60) is hydraulically controlled by the fuel pressure in a pressure chamber (64) and is longitudinally displaceable counter to a closing force, whereby it controls at least one injection opening (68). A control valve (30) is arranged in the housing, by which the connection of the pressure chamber (64) with a fuel high-pressure source (10) and/or a relief chamber (72) is controlled. The control valve (30) is connected to the relief chamber (72) via a control connection that can be closed by an additional valve, which has a piston (45) as a control member that moves synchronously with the valve member (60) in the longitudinal direction and which has an end section (44) on which a control edge (93) is formed, which after part of the total stroke of the piston (45) dips into a control section (48) of the control connection and closes it (Fig. 1).",
