摘要： Centrifugal separation apparatus (110) for removing contaminants from a pumped liquid such as engine lubricant comprises separation rotor means (130) spun about axis (124) at high speed by a jet (178) of the liquid impinging upon impulse turbine blades (174). The rotor includes a separation and containment vessel (132) having impervious side wall (134) spaced from the rotation axis and at least one end wall (138) open at (142) permit liquid to leave the vessel as fast as it can enter, so that a zone (140) is defined adjacent side wall (134) that holds a volume of liquid much less than the whole volume encompassed by the vessel walls and filled in conventional high speed separators. Lower inertia and reduced pressure gradients in the liquid permits it to be spaced further from the axis than is conventional, with improved separation efficiency. Liquid may be supplied to the zone (140) in any convenient manner but as show spent turbine liquid (178') is collected on a rotating surface (158) of a divider wall (152) that spreads and/or directs the liquid to transfer passages (164) from which it is flung centrifugally to the separation zone (140). The outer side wall (134) of the vessel which collects contaminants may be replaceable attachment to the divider wall/turbine part.

摘要： A Centrifugal Separator (10, fig. 1 (a)) for an engine has a rotor (30) mounted within cover (14) for rotation on hollow spindle (42) to the end of which oil is supplied at high pressure to enter the rotor. To prevent the rotor from flying from the base and oil spraying if the cover (14) is removed without stopping supply via optional valve (80), a rotor restraining means (90) forms a ring (91), (fig. 1(b)) which surrounds and overlies a flange of the rotor. The ring may be complete or discontinuous and include an interlock to prevent fitting of the cover and/or supply of oil if it is not in place.

摘要： A centrifugal separator (10) comprises a housing (11) through which extends a spindle on which is mounted a centrifuge rotor (20). The rotor is mounted on journal bearing bushes (31 and 32) that are lubricated by the liquid supplied at pressure to the rotor and the weight of the liquid-filled rotor is carried by magnetic repulsion thrust bearing (40) comprising permanent magnets (43, 46) secured one each to the housing and rotor. The spaced magnets run without contact noise and frictional losses, improving rotational speed available from the supply pressure, and lateral (radial) instability that is inherent between repelling magnets and normally disliked puts a radial bias on the journal bearings which may result in quieter running by inhibiting vibration, particularly when the journal bushes are starved of liquid supply during wind-down. Alternatively or additionally, supply pressure induced lift of the rotor may be borne by a magnetic repulsion thrust bearing (360, Fig. 3). The magnets may be permanent and/or electromagnets.

摘要： A centrifugal separator (100) for non-cohesive particulates, such as are found in transmission oils and hydraulic liquids, rather than the cohesive combustion products found within internal combustion engine lubricants, consists of a housing (11) enclosing a vertical spindle (16) on which spins a liquid reaction driven rotor container (20). The container is divided internally by inwardly extending partition wall (35) into separate outflow chambers (36 and 37). Non-cohesive particulates which separate from the liquid, and are held against the peripheral side wall (241) by centrifugal force during rotation, slump therefrom in the absence of rotation and risk forming a slurry that gets carried to the outflow chamber. Barrier wall means (140) consists of an upwardly extending, outwardly inclined barrier wall (141) forming a contaminant retention region (144) with a restricted neck (143) defined by the separation of the barrier wall edge (142) from the side wall, that permits deposits on the barrier wall to carry to the peripheral side wall and spread across it during rotation, does not interfere with slumping absent rotation and inhibits the slumped material from being washed into the outflow before rotation re-commences.

摘要： 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 (15) by ejection of the lubricant supplied to the canister at elevated pressure by way of apertures (281, 282) in a bearing tube near the upper end of the canister. The canister is separated into upper separation chamber (33) and lower outflow chamber (34) by an annular partition wall (30) 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 (50) having an inclined surface (51) supporting alternate separation ribs (56) and scavenging apertures (57). 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.
