  • 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 48 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 a deformation of at least one element, among the outer and inner enclosures 32, 34, the conduit 48 and the first and second closure plates 42.1, 42.2, which tends to modify the spacing between the first and second closure plates 42.1, 42.2 at the first and second orifices 50.1, 50.2.
  • connection zone 52.1, 52.2 surrounding each conduit 48 can move in the axial direction DA relative to the tubular interface 38 and compensate for the dimensional variation between the first and second closure plates 42.1, 42.2, which makes it possible to limit the stresses on the first and second connections 54.1, 54.2 and to reduce the risks of damage to said first and second connections 54.1, 54.2.
  • this temperature difference causes different deformations of the tubular interface 38 and of at least one of the first and second closure plates 42.1, 42.2.
  • the differences in deformation are all the more significant as the materials of the tubular interface and the closure plates are different, for example when the tubular interface 38 is made of a composite material and the closure plates are metallic.
  • the fact that a closure plate 42.1, 42.2 comprises at least one deformable zone 58 allows radial deformations of said closure plate, which makes it possible to compensate for the differences in deformation between this closure plate and the tubular interface.
  • the tank 30 comprises several conduits 48, 48', 48" which pass through the first and second closing plates 42.1, 42.2.
  • each 48, 48', 48" conduit is straight
  • each conduit 48, 48', 48" comprises an intermediate section 60 located between the first and second closure plates 42.1, 42.2.
  • the intermediate section 60 has a curved axis A48 and an excess length between said first and second closure plates 42.1, 42.2.
  • This excess length of the intermediate section 60 of the conduit 48 makes it possible to compensate for the dimensional variation between the first and second closure plates 42.1, 42.2, to limit the stresses on the first and second connections 54.1, 54.2 and to reduce the risks of damage to said first and second connections 54.1, 54.2.
  • the axis A48 of the intermediate section 60 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 50.1 of the first closure plate 42.1 crossed by a conduit 48 is located at 6 o'clock, then the second orifice 50.2 of the second closure plate 42.1 crossed by the same conduit 48 is located at 12 o'clock.
  • each of them comprises an intermediate section 60, 60', 60" which has a curved axis A48, A48', A48". All the intermediate sections 60, 60', 60" follow circular helix-shaped trajectories having approximately the same helix axis, at least between the first and second closing plates 42.1, 42.2.
  • the invention is not limited to the embodiments described above.
  • the first and second closure plates 42.1, 42.2 could be positioned respectively in line with the walls of the external and internal enclosures 32, 34.
  • the tank 30 comprises a first wall 42.1 connected to the external enclosure 32 at at least one connection zone 46, a second wall 42.2 connected to the internal enclosure 34 at at least one connection zone 46 as well as at least one conduit 48 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 50.1, 50.2 to allow the conduit 48 to pass through the first and second walls 42.1, 42.2.
  • the tank 30 comprises, for each conduit 48 and each of the first and second walls 42.1, 42.2, a connection zone 52.1, 52.2 which surrounds the first or second orifice 50.1, 50.2 and comprises a connection 54.1, 54.2 connecting the conduit 48 and the first or second wall 42.1, 42.2.
