Abstract
A self-powered centrifugal separator for removing particulate contaminants from engine lubricant includes a rotor canister which is spun at high speed about a vertical axle by ejection of the lubricant supplied to the canister at elevated pressure by way of apertures in a bearing tube near the upper end of the canister. The canister is separated into upper separation chamber and lower outflow chamber by an annular partition wall which defines a transfer aperture between the chambers by its radially inner edge. The edge of the partition wall also supports concentrically within the separation chamber a separation funnel arrangement having an inclined surface supporting alternate separation ribs and scavenging apertures. Liquid entering the separation chamber is directed radially outwardly and under pressure gradient moves inwardly along the inclined surface. The ribs stand up sharply and create eddies which effect separation of particulate contaminants and their deposition at the surface. Centrifugal forces carry such deposited materials through the scavenging apertures to deposit on the peripheral wall of the canister.
