Abstract (en)

[origin: EP2080894A1] Fuel rail (18) of a combustion engine (22) comprising a main tube (32) with a longitudinal central axis (A) and a cavity (36) forming an inner surface (38), the main tube (32) being designed to contain fuel, a membrane (44) being arranged in the cavity (36) and being fixedly coupled to the inner surface (38) of the main tube (32) in a manner to sealingly separate a damping chamber (48) of the cavity (36) from a fuel chamber (50) of the cavity (36). The membrane (44) is designed to oscillate in axial direction. The membrane (44) and the damping chamber (48) are designed to compensate pressure variations of the fuel in the fuel chamber (50) of the main tube (32).
