ABSTRACT:
The invention comprises an improved rotary apparatus comprising an outer body member having an internal generally axially directed first thrust area. An inner body member is mounted within the outer body member for relative rotation of the two body members. The inner body member has a second generally axially directed thrust area generally opposed to the first thrust area. The body members define fluid passageways and the thrust areas define a fluid-receiving space therebetween in communication with the passageways. First and second annular seals of differing diameters seal between the thrust areas, and a thrust control system is provided for selectively varying the fluid pressure in the annular portion of the fluid-receiving space bounded by the two seals by selectively providing pressure equalizing communication between that portion and a plurality of zones of differing pressures external to the annular portion.
