Abstract:
A fuel tank for a motor vehicle, comprisingat least first and second tank regions of relatively large cross-section forming respective communicating sub-volumes of the tank, a tank region of smaller cross-section forming the communication between the first and second tank regions, wherein the tank region of smaller cross-section in the position of installation of the tank is formed by an upward incursion of the tank bottom into the tank interior between said first and second tank regions, at least one fuel delivery unit in the first tank region, means for venting the tank in the form of only a single common refuelling vent valve for the first and second region of the tank and arranged in the second tank region, at least one compensating line which interconnects the first and second tank regions on the basis of the principle of communicating tubes, means for venting the compensating line, the compensating line being such that equalisation of the filling levels of the intercommunicating first and second tank regions is possible at least at a low filling level only in the event of such a fall in level at which the filling level in the first tank region is less than in the other regions of the tank.
