A tank that includes a tank wall composed of a plastic material, and at least one reinforcing profile member configured to minimize deformation of the plastic tank. The at least one reinforcing profile member is configured for arrangement on an outer side of the tank wall to be engaged by the tank wall and establish a positive material bond connection therewith. The at least one reinforcing profile member has a retaining geometry region with a plurality of openings through and/or into which material of the tank wall extends and onto a rear side of the reinforcing profile member facing away from the tank wall to thereby establish the positive material bond connection between the tank wall and the at least one reinforcing profile member at the retaining geometry region.

A device for fastening tank insert parts, wherein the device has a holding element for holding the tank insert part and at least one elastically deformable clamping device which is connected to the holding element and by means of which a fastening structure can be received. Furthermore, a plastic tank having a fastening structure which is arranged in the interior thereof, and having a device according to the invention which is arranged thereon for fastening tank insert parts.

An operating fluid tank for a motor vehicle, in particular for storing an aqueous additive, comprising: a tank wall made of a thermoplastic material, wherein the tank wall has a top, a bottom and side walls, and the tank wall delimits a tank volume, wherein the tank volume has a height, a depth and a width; and at least one electrically operated heating device having one or more heating elements, the heating element being inserted into an outer depression of the tank wall, or into an outer recess or opening in the tank wall, or into an inner structure that is integrally formed with the tank wall and that extends into the tank volume, and said heating element extending over at least one third of the height of the tank volume and being electrically contacted outside the tank volume.

A system and method for manufacture of the system are provided. In one example, the system comprises a first component, a second component securing the first component to a portion of the system, and a flexible strip with an abrasion resistant coating including a copolymer. The first component or the second component includes a corrosion coating on an exterior surface and the flexible strip is interposed between a surface of the first or second component and the corrosion coating.

Polyoxymethylene polymer compositions and molded articles made from the composition are disclosed that are fuel resistant, particularly diesel fuel resistant, and resistant to highly acidic solutions. The polymer composition contains a polyoxymethylene polymer generally in an amount from about 90% to about 95% by weight. In addition, the polymer composition contains an add neutralizing agent and a plasticizer at a weight ratio that has been found to significantly improve the add resistant properties of the composition.

A plastics container of modular construction includes a first plastics segment and a second plastics segment. The first and second plastics segments are connected to one another by plastics welding. At least one of the first and second plastics segments has a paintable surface layer on an outer side thereof or is comprised of a paintable material.

A compartment for storing fuel in a vehicle having a protective outer structure and an inner structure. The protective outer structure is maintained in position relative to the vehicle during normal operation of the vehicle. The inner structure, which holds fuel, is positioned in the outer structure. The inner structure is maintained in position relative to the outer structure and relative to the vehicle during normal operation of the vehicle. During an impact to the vehicle, the inner structure is configured to move independent of the outer structure.

A fuel tank vent valve includes a venting apparatus for regulating discharge of fuel vapor from a fuel tank and admission of outside air into a fuel tank. The vent valve is used to regulate pressure in a fuel tank.

A fuel tank device for a vehicle that includes a plastic fuel tank having a conductive outer layer, a plastic filler pipe for filling the fuel tank, at least one metallic component, and an electrical connector to connect the metallic component to the conductive outer layer of the filler pipe. The metallic component is grounded via the electrical connector and the conductive outer layer of the filler pipe.

This method for manufacturing a pipe (2) for a vehicle fuel tank involves—molding a wall, comprising an inner layer (6) made from ethylene vinyl alcohol (EVOH) and an outer layer (8) made from a polymer suitable for welding, in a mold comprising at least one female shoulder that creates at least one male shoulder on an outer surface of an end portion of the wall during molding, then—cutting off the end portion of the wall.
