  • the invention is not limited to this embodiment for the tubular interface 38.
  • the hydrogen tank 30 comprises at least one conduit 46 which passes through the first and second closure plates 42.1, 42.2 and has a first end 46.1 opening outside the external enclosure 32 as well as a second end 46.2 opening into the internal enclosure 32.
  • the first closure plate 42.1 comprises a first orifice 48.1 to allow the conduit 46 to pass through said first closure plate 42.1.
  • the reservoir 30 comprises a first connection 50.1 connecting the conduit 46 and the first closure plate 42.1.
  • the second closure plate 42.2 comprises a second orifice 48.2 to allow the conduit 46 to pass through said second closure plate 42.2.
  • the reservoir 30 comprises a second connection 50.2 connecting the conduit 46 and the second closure plate 42.2.
  • the first and second connections 50.1, 50.2 are rigid connections. Each of them is a sealed connection ensuring a fluid seal between the conduit 46 and the first or second closure plate 42.1, 42.2.
  • each of the first and second connections 50.1, 50.2 comprises at least one weld bead surrounding the conduit 46 and ensuring a seal between the latter and the closure plate 42.1, 42.2.
  • the invention is not limited to this embodiment for the first and second rigid connections 50.1, 50.2.
  • the first or second connection 50.1, 50.2 could be in the form of a flange.
  • tubular interface 38 and the closure plates 42.1, 42.2 are not further described because they may be identical to those of the prior art.
  • Each conduit 46 comprises an intermediate section 52 located between the first and second closing plates 42.1, 42.2.
  • the intermediate section 52 has a curved axis A46.
  • the axis A46 is not rectilinear between the first and second closure plates 42.1, 42.2 so that the intermediate section 52 of the conduit 46 has an excess length between said first and second closure plates 42.1, 42.2.
  • This excess length corresponds to the difference in length between, on the one hand, the length of the intermediate section 52 considered along its curved axis A46 and, on the other hand, the distance between the closure plates 42.1 and 42.2 considered along the axis of revolution A38.
  • the outer enclosure 34 and the first closure plate 42.1 are in contact with an environment at room temperature while the inner enclosure 34, the second closure plate 42.2 and the section of the conduit 46 located in the inner enclosure 34 are in contact with a fluid at a cryogenic temperature, significantly lower than the room temperature.
  • This temperature difference causes deformations of unequal values for at least two elements among the inner and outer enclosures 32, 34, the conduit 46 as well as the first and second closure plates 42.1, 42.2. This tends to modify the spacing between the first and second closure plates 42.1, 42.2 at level of the first and second orifices 48.1, 48.2 and consequently to generate significant stresses in at least one of the aforementioned elements.
  • the excess length of the intermediate section 52 of the conduit 46 makes it possible to compensate for this dimensional variation between the first and second closing plates 42.1, 42.2, to limit the stresses on the first and second connections 50.1, 50.2 and to reduce the risks of damage to said first and second connections 50.1, 50.2.
  • the axis A46 of the intermediate section 52 follows a trajectory in the form of a circular helix at least between the first and second closure plates 42.1, 42.2.
  • the first and second closure plates 42.1, 42.2 are substantially parallel to each other and angularly offset by approximately 180°. Consequently, if the first orifice 48.1 of the first closure plate 42.1 is located at 6 o'clock, as illustrated in the Figure 5 , the second hole 48.2 of the second closing plate 42.1 is located at 12 o'clock, as illustrated in the Figure 6 .
  • the tank 30 comprises several conduits 46, 46', 46" which pass through the first and second closure plates 42.1, 42.2, each of them comprising an intermediate section 52, 52', 52" which has a curved axis A46, A46', A46” .
  • all the intermediate sections 52, 52', 52" follow trajectories in the form of a circular helix having approximately the same helix axis, at least between the first and second closing plates 42.1, 42.2.
  • the tank 30 comprises a first wall 42.1 integral with or forming part of the external enclosure 32, a second wall 42.2 integral with or forming part of the internal enclosure 34 as well as at least one conduit 46 passing through the first and second walls 42.1, 42.2.
  • the first and second walls 42.1, 42.2 respectively comprise first and second orifices 48.1, 48.2 to allow the conduit 46 to pass through the first and second walls 42.1, 42.2.
