Abstract (en)
[origin: GB2328890A] A self-powered centrifugal separator for removing particulate contaminants from engine lubricant includes a rotor canister 20 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 282 ... in a bearing tube near the upper end of the canister. In the upper end wall 23, axial discontinuities in the form of embossed ribs 401, 402 ... define between them shallow channels and direct the newly injected lubricant along the channels towards radially outer regions of the canister. The ribs extend not only radially outwardly, but also in a circumferential direction. The circumferential direction may be leading or, preferably, trailing with respect to the rotation direction of the rotor that results from ejection of the lubricant, to increase the time spent by lubricant at radially outer regions of the canister where centrifugal separation is most efficient.
