Abstract
A multi-passage swivel joint for simultaneous transfer of a plurality of separate fluids between two groups of conduits, the second group rotating about the first group has a plurality of sliding contact seals with a bundle of flow passages in deformable sheaths providing segregation continuity on the one hand for large rotations by sliding of the seals and on the other hand for small alternating angular motions by elastic deformation of at least one deformable sheath defining the flowpaths. The stiffness of the deformable sheath compared with the force required for causing the seals to slide being such that the coefficient of friction of the seals has a value such that sliding occurs before the maximum allowable deformation of the sheaths is reached.
