ABSTRACT:
A fuel feed system of an internal combustion engine, in which for damping fuel oscillations which are excited by the closing of injection valves and which occur amplified in a predetermined rotational speed range, a damper is attached to the distributor pipe opposite to a regulator. The damper is of the same type of construction and size as the regulator and forms together with the same a resonator-antiresonator system, whereby the fuel column oscillates to and fro with low flow losses between the regulator and damper.
