A J-shaped temperature-resisting plastic packing ring has the leg portion thereof sealed against the adapter ring with an elastomeric O-ring and the hooked portion thereof loaded by a garter spring against the inner surface of the inner peripheral wall of the casing. A ferrule ring fits in the adapter and is pressed by a wave spring against the elastomer O-ring to seal the J-packing against the adapter ring. This ferrule has one or more radially projecting ears fitting in a groove at the back end of the adapter ring and this groove is slotted at intervals to permit assembly of the ferrule into the adapter. Thus each of the components of the inner assembly can be separated by rotating the ferrule to a align the ears thereof with the gaps in the adapter permitting the ferrule to drop out of the adapter.

4,299,398	Nov. 10, 1981	Pressure Compensating Shaft Seal	Edward C. Wahl	Arlington Heights, Cook County, IL	Abstract: Relatively rotating face ring-type shaft seals especially useful for sealing the shaft bearings and lubricant chamber of mud motor driven downhole drill rigs, have a plurality of telescoped annular seal rings slidably mounted in an annular carrier element and riding over the radial face on a face ring to define a sealed intermediate chamber therebetween. This intermediate chamber may be filled with lubricant. Either the telescoped rings or the face rings rotate with the shaft. Biasing means, such as a plurality of springs, load end faces on the seal rings against the radial face of the face ring. Pressure transmission means, such as pistons, O-rings, or the like, mounted in either the carrier element or the face ring, are loaded by the ambient media pressure, such as drilling fluid, to maintain pressure in the intermediate chamber responsive to the pressure of the ambient media. When the areas of the pressure transmission means exposed to ambient pressure and to intermediate chamber pressure are equal, a zero or negligible pressure differential will be maintained across the outer telescoped seal ring to prevent the ambient media, which is frequently quite abrasive, from entering the outer sealing ring interface. The inner telescoped seal ring serves as an auxiliary back-up face ring seal for the protected bearing chamber. Since the abrasive media being sealed does not enter the interfaces of the rings, the end faces of the inner and outer sealing rings riding on the face ring can be reduced or narrowed to a minimum and coated with a hard facing material such as tungsten carbide.

An annular, stationary floating member surrounds the shaft and is exposed in the internal bore. The floating member includes a surface in sealing engagement with the rotary seal member. An annular slip ring is disposed in the internal bore, and in contact with the floating member and the contact surface. The slip ring provides an articulated link between the floating member and the contact surface of the stationary member, by virtue of being radially displaceable along a rear surface of the floating member.
