Abstract:
1. A gas cleaning separator for separating a flowable mixture of substances of different densities, the separator comprising: a housing defining an inner space, a rotor assembly for imparting a rotary motion onto said mixture of substances, the rotor assembly being mounted to the housing via an upper bearing and a lower bearing, and located in said inner space and rotatable about an axis relative to the housing, wherein the rotor assembly comprises an inlet for receiving said mixture of substances, an outlet from which said substances are ejected from the rotor assembly during use, and a flow path for providing fluid communication between the inlet and outlet, wherein the outlet is positioned more radially outward from said axis than the inlet; a turbine unit for providing rotation of the rotor assembly; and the rotor assembly further comprising a rotary shaft coincident with said axis and mounted to said housing, wherein a first end portion of the rotary shaft extends through said housing to a position exteriorly of said housing where the rotary shaft is connected to said turbine unit, a fluid passageway extending axially through the rotary shaft the fluid passageway being in communication with the upper bearing for conveying an oil mist through the rotary shaft to lubricate the upper bearing said fluid passageway having an opening positioned exteriorly of said housing; and wherein the rotor assembly further comprises a flow control arrangement for controlling fluid entry to said fluid passageway from the exterior of said housing, the flow control arrangement being positioned proximate said turbine unit, wherein the flow control arrangement comprises a turning arrangement for imparting, onto fluid entering said passageway, a rotary motion along a path radially outward from the shaft fluid passageway.
