Abstract:
Process for manufacturing a fuel tank (1) having a plastic wall, according to which: 1. a plastic parison comprising two distinct parts is inserted into an open two-cavity mould; 2. a core is inserted inside the parison, said core bearing two parts of a reinforcing element (3, 4) capable of securing (creating a link between) two different locations inside the parison; 3. the parison is pressed firmly against the mould cavities (generally by blowing through the core and/or creating suction behind the cavities); 4. the two parts of the reinforcing element (3, 4) are fixed at the two locations of the parison using the core; 5. the core is withdrawn; 6. the mould is closed again, bringing its two cavities together in such a way as to grip the two parts of the parison around their periphery in order to weld them together (2); 7. a pressurized fluid is injected into the mould and/or a vacuum is created behind the mould cavities in order to press the parison firmly against the mould cavities; 8. the mould is opened and the tank (1) is extracted; 9. an opening is made into the tank wall; and 10. through said opening, at least a third part of the reinforcing element is put in place in order to link/connect the two first parts together.
Abstract:
Tank for storing an internal combustion engine exhaust gas liquid additive, said tank comprising a wall defining an internal volume, an electrical component (3) located in the internal volume and at least one electric cable (4) making it possible to connect said component to a voltage source outside the tank, at least one portion of the electric cable being inserted into an intermediate part (6) connected to a base plate (1) mounted over an opening in the wall of the tank, in which the base plate incorporates a casing mounted in a leaktight manner around an orifice in the base plate, in which the intermediate part is fastened by quick- connect coupling and which also comprises an electrical connector (11) to which the electric cable is connected in a leaktight manner with the aid of a seal (7) and which emerges from the orifice in the base plate to the outside of the tank, the seal being inserted between the intermediate part and the connector and/or into a housing (8) of the intermediate part.
Abstract:
Method for manufacturing a flexible heater comprising a resistive track enclosed in two sheets of electrically insulating plastic material, said track comprising electrical connections to which electrical wires are connected, the method comprising the steps of: -enclosing the resistive track in the two sheets of electrically insulating plastic material - connecting the electrical wires to the electrical connections of the resistive track - putting an open mould around the connection area - injecting a liquid casting formulation into said mould - curing said composition - removing the mould.
Abstract:

Abstract:
Plastic fuel tank comprising an upper wall (1), a lower wall (2), at least one kiss point (21) formed by welding together a multiplicity of contact points of the upper and lower walls and an accessory (4), characterized in that: both the upper and lower tank walls show a concave recess (3,21) in the kiss point area so that the weld of the kiss point is located in between the planes defined by the upper and lower walls respectively; the bottom of the upper concave recess extends substantially beyond the weld of the kiss point, while the bottom of the lower one does not; the accessory is at least partially located under the extension of the bottom of the upper concave recess. Process for manufacturing such a fuel tank.
Abstract:
