SYSTEME DE RESERVOIR DE CARBURANT ET PROCEDE DE FABRICATION D'UN SYSTEME DE RESERVOIR DE CARBURANT

摘要

The fuel tank (2a) has a filler pipe (3) connected to it with an insert (4) containing a non-return valve (8), the tank, (3) and (4) all being made from a weldable plastic material. At least one of the components is fitted with an electric heating element (5) to which a current is applied after assembly so that adjacent surfaces are welded together. The fuel tank (2a) has a filler pipe (3) connected to it with an insert (4) containing a non-return valve (8), the tank, filler pipe and insert all being made from a weldable plastic material. At least one of the components is fitted with an electric heating element (5) to which a current is applied after assembly so that adjacent surfaces are welded together. The heating element is designed to cover all the contacting surfaces of the assembled components, and the filler pipe and tank can be welded together directly or via a flange (10) on the insert. An independent claim is also included for a method of making the fuel tank incorporating the electric heating element by welding adjacent surfaces.
