ABSTRACT:
A dynamic seal between the high pressure discharge chamber of a centrifugal gas compressor and a sump chamber in which the driving machinery for the impeller of the compressor is contained, the sump chamber in normal operation being maintained at substantially the same pressure as the pressure at the inlet of the compressor impeller is formed by the opposing faces of a seal stator and a seal rotor, the seal being vented at an intermediate location along the axial extent of the seal inwardly through the rotor and to the space at the inlet or suction side of the impeller.
