Abstract
A fuel injection device for internal combustion engines having a high pressure accumulation chamber, which can be filled by a high pressure fuel pump and from which high pressure lines lead to the individual injection valves. Control valves for controlling the high pressure injection at the injection valves, as well as an additional pressure storage chamber between these control valves and the high pressure accumulation chamber, are inserted in the individual high pressure lines. For a more rapid pressure relief of the injection valve at the end of injection, the valve member of the control valve has a reaspiration collar, which additionally constitutes a throttle to maintain a residual pressure in the pressure line to the injection valve, which throttle precedes the flat seat valve, which opens the communication of the injection valve to a relief chamber.
