Abstract

An oil-laden gas stream flows axially through a tube shaft formed with at least one radially throughgoing inner oil-discharge port and, axially downstream therefrom, with at lest one radially throughgoing inner gas-discharge port. A bearing supports the tube shaft for rotation about the axis and is formed axially level with the ports with respective radially throughgoing outer oil-discharge and gas-discharge ports. An oil separator inside the tube shaft axially between the oil-discharge ports and the gas-discharge ports is oriented to deflect oil particles from the stream radially outward such that the oil flows out through the inner and outer oil-discharge ports and the gas stream can flow downstream out through the gas-discharge ports.
