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.

Flexible coupling for fluid ducts

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 flexibiity while minimizing the number of necessary sealing elements.

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.

This automatic lubricator is an adaption of sound hydraulic principle, that is the application of lubricant over a sustained time period by pressure in the lubricant. The novel feature is that the design permits readily available pressure from a service gun to be directly responsible for the pressure application, which is then trapped in the device, and made to feed out slowly to the surfaces requiring lubrication. Also, included in the preferred form of the device is a gage to indicate visually the quantity of lubricant within the device.
