The volume of a gaseous space in the fuel storing chamber is reduced, in comparison with a fuel tank in which a lower wall does not deform, by an amount corresponding to a reduction of the volume of the fuel storing chamber achieved by the curvature of the lower wall. An amount of fuel not discharged from the fuel storing chamber via a fuel passage but remaining near a peripheral end portion of the lower wall of the fuel storing chamber due to the upward curvature of the lower wall is discharged via a residual fuel discharging pipe, so that the residual fuel amount of the fuel storing chamber is minimized.

Each wall has an inward projecting indentation of the structure which engage one-another at their distal ends or bottom portions, preferably, via a welded plastic engagement area. The indentations have a consistent wall thickness which has a higher cross-sectional area than the stress relief feature causing the stress relief feature to tear as opposed to the tank walls thereby assuring fuel tank integrity.

Abstract: A container for fluids, in particular fluids containing gas, comprises an outer casing of flexible, pressure resistant material, at least a gas and/or fluid tight inner casing of flexible material lying inside the outer casing and being separated therefrom, and at least a filling connection for filling the inner casing. As a result, the container is collapsible so that filling the container may take place from the collapsed condition and filling is therefore possible without pressure difference while the fluid does not enter an empty space. The egress of gas from the fluid is substantially reduced thereby. When fluid is discharged from the containe, the volume of the container can also decrease by collapsing so that also during use of the fluid gas is prevented from egressing. Consequently, the quality of the fluid is maintained, both during filling of the inner casing with fluid and during discharge of fluid from the inner casing.

The arcuate surface portion of one of the closure modules abuts contiguously against an interfacing surface portion of an adjacent one of the closure modules. The closure modules are particularly useful for use with multi-cell tanks and vessel bodies, especially tanks and vessels suitable for storing liquid propane.

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.

Abstract: In the case of a filling pipe for a fuel tank a branching element is arranged in a section of the filling pipe. The flow of the inflowing fuel preferably runs along an outer wall of the filling pipe, so that a subflow is in each case conducted directly to the antisurge tower through a lower cross-sectional area. Larger volume flows, which completely fill the cross section, pass for the most part directly into the fuel tank. By this means, a sufficient basic supply of the antisurge tower is ensured irrespective of the volume flow produced during filling.

Abstract: A plastic fuel tank for use in a vehicle to carry gasoline, diesel fuel and the like has an upper wall, a lower wall and side walls. In order to inhibit relative deflection of the upper and lower wall toward each other, such as may occur when vacuum pressure is introduced into the tank by typical fuel sensor systems, the tank is equipped with a resilient columnar member extending between the upper and lower walls. The resilient columnar member thus limits deflection and changes in volume of the tank to not greater than one liter. The columnar member is hollow so as to not reduce the fuel capacity of the tank. The columnar member may be held in position by structural walls within the tank or by welding to either the top or bottom wall of the tank.
