Abstract
A centrifugal separator for removing particulate contaminants from liquid such as engine lubricants consists of a housing for securing to the engine having a funnel-shaped floor from which oil can drain centrally at a drainage duct. The housing is secured to a legged spider or cage carrying a hollow axle by which the apparatus is secured to the engine and oil delivered to a separation rotor canister. Liquid ejected tangentially from rotor nozzles to cause it to rotate tends to flow around the inside of the housing as a vortex and to prevent rotation of the canister being interfered with by climbing of the vortex or splashing of the liquid from such vortex, one or more vortex disruption vanes are formed with the legs of the cage to deflect liquid.
