A resilient ball joint support including two plates movable with respect to each other and connected together by at least one ball joint, the transmission of a load between the plates being provided, partly through at least one cushion formed of at least one sealed envelope confining at least one fluid which is pressurized by the action of the load and partly by at least one ball joint centering the plates with respect to each other.

Resilient ball joint support

A resilient ball joint support is provided including two plates movable with respect to each other and connected together by at least one ball joint, the transmission of a load between said plates being provided, partly through at least one cushion formed of at least one sealed envelope confining at least one fluid which is pressurized by the action of said load and partly by at least one ball joint centering said plates with respect to each other.

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.
