US 6,293,420 B1 · Fuel tank

Abstract

A fuel tank for a motor vehicle is provided in its interior with a component for reducing fuel surge movements. To avoid troublesome noises produced by fuel movement the component comprises a wall element at a spacing from the end of the tank that is the front end or the rear end in the direction of travel. The wall element extends at least over a substantial part of the height and the width of the tank and is so shaped that the wall element surfaces extend at least predominantly not in planes which extend perpendicularly to the direction of travel, to prevent fuel from impacting unimpededly against those surfaces perpendicularly thereto. Those surfaces thus represent divisions in the fuel tank. The volume of the fuel between the wall element and the respective tank wall surface to be shielded is not sufficient to produce noises which are a nuisance when travel movements occur.

Dependent claims

A fuel tank for a motor vehicle, said fuel tank comprising:

a first end and a second end that in the direction of vehicle travel are a front end and a rear end respectively;
two wall elements in the tank interior for reducing fuel surge movement therein, the wall elements being arranged within the tank at a spacing from said ends of the tank and extending at least over the major part of the height and the width of the tank and being of such a shape that their boundary surfaces extend across the tank at least predominantly not in planes which extend perpendicularly to said direction of travel;
a discharge opening within the wall elements;
and
a surge pot within the wall elements in the vicinity of the discharge opening.
