ABSTRACT:
The weight of the rotor of the machine is carried by a liquid lubricated thrust bearing while being guided by one or more gas lubricated centering elements. The thrust bearing is isolated from the rotor casing so that the lubricating liquid cannot contaminate the pumped gas. The machine is constructed for ratings in excess of 500 kw.
