Abstract:
For use with a top drive power unit supported for connection with a well string in a well bore to selectively impart longitudinal and/or rotational movement to the well string, a feeder for supplying a pumpable substance such as cement and the like from an external supply source to the interior of the well string in the well bore without first discharging it through the top drive power unit including a mandrel extending through a sleeve which is sealably and rotatably supported thereon for relative rotation between the sleeve and mandrel. The mandrel and sleeve have flow passages for communicating the pumpable substance from an external source to discharge through the sleeve and mandrel and into the interior of the well string below the top drive power unit. The unit can include a packing injection system and novel seal configuration.

Claim (Index 34):
A top drive swivel insertable into a drill or work string comprising:\n (a) a mandrel having upper and lower end sections and rotatable with upper and lower drill or work string sections having a drill or work string passage, the mandrel including a longitudinal passage forming a continuation of a passage in the drill or work string sections; (b) a sleeve having a longitudinal sleeve passage, the sleeve being rotatably connected to the mandrel; (c) a pair of spaced apart packing units between upper and lower end portions of the mandrel and sleeve, the packing units preventing leakage of fluid between the mandrel and sleeve; (d) the sleeve comprising an inlet port positioned between the spaced apart packing units; (e) the mandrel comprising at least one radial port in fluid communication with both the inlet port and the longitudinal passage to supply pressurized fluid from the inlet port to the longitudinal passage and the drill or work string passage in drill or work string sections; and (f) wherein each of the packing units comprise a plurality of packing rings, at least one packing ring in each packing unit being comprised of a sealing packing ring being spaced close to a lubricating rope seal.
