ABSTRACT:
A connector 10 for a fluid-flow line comprising a pair of truncated spheres, the inner 14 nesting within the outer 12, with the truncated ends facing in opposite directions. The non-truncated ends of the spheres are each connected to a different circular disc with a grid structure, called an end member 22, 22'. An adjustable tension wire 24 is stretched between the end members 22, 22' and holds the spheres 12, 14 together. A fluid-bearing seal 16 is affixed to the outer surface of the inner sphere 14 and is in contact with the inner surface of the outer sphere 12. A second seal 18 is attached between the spheres 12, 14 but spaced from the fluid-bearing seal 16 to form a seepage space 30 therebetween. The fluid-bearing seal 16 is formed with internal tubes 32 which permit a small leakage flow from the main flow into the seepage space 30 between the upper surface 34 of the seal 16 and the inner surface of the outer sphere 12 so as to reduce friction between these surfaces. The leakage fluid in the seepage space 30 is drained off continually by an outlet seepage tube 20.
