Abstract
A fuel tank for vehicles is constructed so that any disturbing generation of noise in the fuel tank due to swashing fuel, particularly during acceleration and deceleration, is prevented. For this purpose wall sections of the fuel tank are equipped internally with a structured surface forming stabilization chambers. At the fuel-free regions of these walls sections, the swashing wave front of the fuel is dissolved over a large area, by the surface structure, into a plurality of wave sections which are distributed and diverted, whereby fuel movements which customarily generate swashing noises are effectively attenuated.
