Abstract
An air oil separator adapted for attachment to a dry sump type oil pump incorporates a novel centrifuge and air ducting system. The centrifuge is formed of two disks axially spaced on a hollow rotatable shaft with the shaft having small air passages located between the disks that extend radially through to a hollow interior of the shaft. An air duct couples an open end of the centrifuge shaft to an air outlet for exhausting air from the shaft interior to the upper air side of the oil sump. Axially rotating at high speed the centrifuge separates air from inputted oil by throwing the oil to the outer reaches of the housing where the oil exits through an outlet and the separated air is exhausted through the shaft and duct.
