Patent abstract
The invention is a sealing assembly for equipment with movable shafts—such as coaxial and side port swivels, hydraulic swivels, and rotary control devices—that prevents the loss of a high pressure fluid through the clearance existing between a housing and the shaft. The invention is disclosed in the context of a coaxial swivel that conducts high pressure fluid from a stationary first conduit to a rotating second conduit that has dynamic runout, and may be misaligned relative to the first conduit.
