Abstract: A fluid coupling accommodates misalignments of ducts to be connected in any one or any combination of three basic directions, these being axial, angular and radial. The coupling also provides for duct flexibility while minimizing the number of necessary sealing elements.

Abstract: The object of the invention is to provide a coupling for fluid conveying ducts which has built in capability to allow for radial and/or angular misalignment of the ducts which it is coupling and also retain axial flexibility. Such coupling includes a pair of interconnectable coupling half assemblies each with eccentric openings (17) for passage of one of the tube ends (10) therethrough with their associated ends in spaced relation. These coupling half assemblies also may include abutting faces disposed in a plane (P) oblique to their longitudinal centerline (C). Relative adjustment of the eccentric openings (17) provides radial adjustment of the tubes (10) while relative adjustment of the coupling half assembly faces along the plane (P) provides angular adjustment of the tubes (10). Any combination of axial, radial, and/or angular misalignment of the tubes (10) within the dimensional envelope of the coupling can be accommodated by manipulation of the parts relative to each other.
