Problems solved by technology

Incorporating accessories into such cases raises the question of how to fasten components to openings made in these cases in a sealed and impermeable manner
Especially in the case of tubular parts, this leads to locally over-thickened, material-intensive and time-consuming (additional manufacturing steps), so sometimes not insignificant additional costs arise

no. 1 Embodiment approach

[0044] Figure 1 shows a first specific embodiment of the invention: the multilayer wall (1) of the box has an opening whose profile has a conical shape towards the inside of the box. Angle (8) is the angle of the tapered surface. The multilayer nozzle (2) has an end whose profile matches the profile of the opening in the tank in such a way that the outer layer of the nozzle is welded to the tank at the opening along the weld zone (3) on the outer layer.

[0045] Figures 2 and 3 show two further embodiments in which the nozzle (2) is welded in such a way that the inner layer of the nozzle (2) is welded to the outer layer of the tank wall (1) (Fig. 2), or weld the outer layer of the nozzle (2) to the inner layer of the wall (1).

[0046] Figures 4 and 5 show the welding of two nozzles, one of which is actually formed by a tubular protuberance of the fuel tank (not shown in these figures). In both cases, there is an overlap in the welding area of ​​the inner layer of the nozzl...

Abstract

A system for fastening, by welding, a component having a portion with a conical surface profile to a motor vehicle fuel tank that includes an opening whose perimeter has a conical surface profile. The welding is carried out between at least one portion of the conical surface of the perimeter of the opening in the tank and at least one portion of the conical surface of the component.

Description

technical field [0001] The invention relates to a system for fastening two components, a related fastening method and a fuel system. Background technique [0002] Liquid fuel tanks or gaseous fuel tanks used in industry or on board vehicles of various types must generally meet the standards of tightness and permeability corresponding to the type of use for which they are designed, as well as the environmental requirements with which they must comply. At present, in Europe and around the world, the requirements for the emission limits of pollutants in the atmosphere and the environment are becoming more stringent to a large extent (for example, the PZEV (“Partial Zero Emission Vehicle”) standard in California). Additionally, allowable discharge limits have become so low that losses due to leakage and permeation at the junction between the accessory and tank have accounted for a relatively high proportion of tank / accessory system losses . [0003] In addition, it is becoming...
