AIR-SEALED OIL DEFLECTOR Abstract of the Disclosure An air-sealed oil deflector is disclosed which prevents leakage of oil from bearings or a rotating shaft and which prevents the ingestion of unfiltered atmospheric air which can lead to contaminant build-up and damage to the shaft. The air-sealed deflector includes an annular plenum surround- ing the shaft and an annular feed slot interposed between the shaft and the plenum to fluidly interconnect the plenum with the chamber between at least two seal rings immediately adjacen the shaft. The plenum is adapted to receive a continuous flow of forced air from an air supply system including an air prime mover and means for filtering air drawn from the atmosphere which serves as the ultimate air source. The plenum being relatively large in volume, and having a cross-sectional area large with respect to the air feed conduit to the plenum, provides a very uniform source for air flow radially inward, in a sheet-like fashion, toward the shaft through the feed slot. The air-seal is formed as the sheet-like flow of air is released between working clearances between the shaft and the seal rings. A perforated diffuser ring mounted in the feed slot contributes to the desired pressure distribution and eliminates detrimental viscous drag effects.
