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, from which chamber high pressure lines lead to the individual injection valves. Control valves for controlling the high pressure injection at the injection valves are formed in the individual high pressure lines. Additional pressure storage chambers are inserted in the individual high pressure lines as well, between these control valves and the high pressure accumulation chamber. In order to prevent the high system pressure from continually contacting the injection valves, the control valve is embodied so that during the injection pauses, it closes the communication between the injection valve and the pressure storage chamber and opens a communication between the injection valve and a relief chamber.
