ABSTRACT:
An improved pressure seal assembly for rotary machinery. The assembly utilizes a buffer oil flowing through a seal ring surrounding the rotating shaft of the machinery. The seal ring includes a plurality of openings about its periphery to pass the oil through the ring to a number of bearing pads. The oil serves to cool, lubricate, seal and damp the seal ring. The assembly reduces oil loss to the pressurized environment to a minimum.
