1463243 Centrifugal oil cleaner SERBOL 139 AB 31 Jan 1975 [8 Feb 1974] 4237/75 Heading B2P A centrifugal oil cleaner comprises a hollow rotor 10 rotatably journalled in a housing 1 about a vertical axis, a dish-shaped member 14 located in the rotor interior spaced from the base of the rotor and having a downwardly directed rim 15 defining an annular gap 15' between its lower edge and the inner surface of the base of the rotor, and an inlet 12 for supplying oil to the space between the member 14 and the rotor base, the dimensions of the gap 15' and of the inlet 12 being such that the oil passes substantially radially outwards through the gap with a smaller speed than it passes through the inlet into the said space. Oil to be cleaned is pumped through a channel 5 in the housing 1 and a passage 7 in the rotor shaft 8 and exits into the space between the member 14 and the rotor base through a plurality of radial inlets 12. The oil issuing from the gap 15' at reduced speed flows in the direction of the arrows P inwardly against the direction of centrifugal force and upwardly towards outlet nozzles 16. Blades 13 integrally formed with the member 14 assist this flowing action. The contaminants which are heavier than the oil are acted upon by centrifugal force and deposited on the inner surface 19 of the rotor wall. The clean oil flows outwardly through the nozzles 16 via tangential openings 17 and produce a reaction which drives the rotor. The oil impinges on a cap 3 clamped to the housing and runs downwardly to the bottom of the housing and outwardly through a channel 6. The separated contaminants are sucked continuously or intermittently through radial tubes 18 which communicate through a channel 20 in a nut 24 and through a nipple 22 rotatably supported on the nut and connected to a suction source. The nut 24 serves to hold a cap 11 in sealing engagement with the rotor. In a modification there are no suction tubes and the nut 24 has no central bore, cleaning of the rotor being perfomed manually after releasing the caps 3, 11 when the rotor is stationary.
