ABSTRACT:
A seal suitable for use in a barrel-type rotary machine having an inner casing mounted within an outer casing to provide a chamber therebetween which is pressurized by exposing the chamber to high pressure fluids processed in the machine. One end of the chamber is substantially enclosed by a pressure responsive resilient member. One end of the member is secured to the inner casing and the opposite end thereof arranged to support a sealing element in non-contiguous relation adjacent to the inner wall of the outer casing. As the chamber is pressurized, the resilient member is forced outwardly toward the outer casing to securely seat the sealing element in positive fluid-tight engagement thereagainst.
