Abstract

Liquid ring compressor, characterized by an eccentric inner rotor ( 6 ) is supported in axles ( 8,9 ) to an outer co-rotor ( 3 ) for the liquid ring, where the beating of the co-rotors ( 11 ) is outside the same axles on each side is enclosed in an enclousure where it on each sides of the bearing ( 11 ) is arranged a rotating lip seal ( 82 ) which lip ( 83 ) abut the axles ( 8,9 ) at low speed, and which at high speed is projected due to centrifugal forces out and lifts itself from the axles, where through holes ( 81 ) through the co-rotor's sidewalls and bearing enclosure, its volume within the liquid ring is aired to the surrounding enclosure ( 1 ), and ensures that it is not created a differential pressure across the bearings and the seals of the bearings.
