ABSTRACT:
A seal to prevent the escape of a liquid and gas mixture from the gap between a rotating shaft and the bore of a housing, which includes an inner ring secured to the shaft and an outer ring secured to the outer wall of the housing bore. A flange-like member is secured to the inner ring and employed to seal the gap between the inner ring and outer ring. The flange includes liquid and gas inlets, an internal network of voids and liquid and gas outlets. The internal void network of the flange member is adapted so that during the rotation of the flange member, gas and liquid oil is suctioned into the flange through the liquid and gas inlets, and are segregated by the rotary motion of the void network of the flange into a predominantly gaseous stream and a predominantly liquid stream.
