Abstract
A damper element for damping compressive oscillations in the fuel circulation circuit of an internal combustion engine is situated directly in the fuel distributor. The damper element includes one or more gas-filled chambers and is manufactured from a resilient material. A bubble-type flexible cord can be used as a damper element. Because of its very simple structure and small mass, the damper element can be integrated in the fuel distributor so that no additional space is required. The damping of the compressive oscillations induced by the switching pulses of the injection valves takes place in the immediate vicinity of each individual injection valve.
