<p>A device for connecting two tubes having a small cross-section perpendicular to a universal coupling element which connects to each other a first component and a second component of an articulated marine structure, said tubes are associated respectively to said first and second components, while said universal coupling element is essentially constituted by a solid core provided with four cross-pins the respective axes of which extend in four orthogonal radial directions. Two opposed cross-pins are supported in respective contact zones by bearing surfaces defined by one of said components, while the remaining two opposed cross-pins are supported in respective contact zones by bearing surfaces defined by the other component. This device further comprises two assemblies each at least one tube element in the form of a planar spiral, the number of spiral tube elements of one of said assemblies being equal to the number of spiral tube elements of the other assembly, each one of said spiral tube elements being arranged centrically about the respective axes of two orthogonally disposed cross-pins of said universal coupling element. Each spiral tube element has an inner end connected to the orifice of a conduit provided in the associated cross-pin, any two of the conduits provided in said cross-pins being connected to each other by a respective conduit integral with said core. The spiral tube elements further have each an outer end, the outer end of one spiral tube element being connected to the tube with said first component, while the outer end of the other spiral tube element is connected to the tube associated with the above-mentioned second component.</p> |
