<p>Centrifuge (10) for removing soot from oil includes rotor (18) adapted to rotate inside centrifuge housing (16) by bearings (36), 38) carried on stationary support sharft (34). Rotor (18) includes a removable lid; a aluminium support casing (21); and a plastic cartridge (23) including a trap with wave formation preventing walls. An annular side oil inlet is provided at the cartridge's top end offset from axis of rotation (19), a winding flow path goes through the cartridge, and an oil outlet is at the cartridge's bottom end. A restriction plug controls oil flow through the rotor. Centrifuge housing (16) includes rotor chamber (32) and die cast aluminium support body (26) with theraded bosses (20). Lid assembly (28) includes rubber vibration isolators enclosing a top end of support body (26). Using the venturi effect, air is evacuated from the rotor chamber to produce a partial vacuum to reduce drag.</p> |
