ABSTRACT:
An oil scavenger system for a face seal including a lubricant scavenger system for retrieving lubricant which has escaped from a first side to a second side of a seal which seals a rotary shaft. The rotary shaft is used on a compressor, pump, or any other machine which involves a lubricant seal about a rotary shaft. A cover encases the second side of the seal, producing a first space therebetween. A first pressure is maintained in the first space. A second space is interconnected to the first space whereby the lubricant may freely pass therebetween. The interconnection may be mounted exterior or interior of the machine. A second pressure is maintained in the second space than in said first space. The second space may actually be in communication with the first side of the seal. The second pressure is less than the first pressure.
