Title: Shaft bearing system

Abstract: A turboexpander associated with a rotary compressor by means of a rotor shaft connecting the two. A bearing housing includes magnetic radial and thrust bearings which control the placement and dynamics of the shaft within the housing. A control passageway extends from the inlet of the compressor to the gas cavity behind the compressor rotor. This passage is controlled by a valve and in turn by the magnetic bearing controller to augment the operation of the active magnetic thrust bearings.
