Abstract:
A gas bearing system has at least one gas bearing ( 30, 32, 34 ) with a moving part and a static part and which can be operated in both aero-dynamic and aero-static modes. The system has a source ( 36 ) of pressurised gas fluidly connected with the bearing and a control system ( 134 ) for regulating the supply of pressurised gas to the bearing in dependence on the rotational speed of the moving part. The system has particular application in a turbocharger ( 1 ) where a flow of pressurised gas from the source is introduced into the bearing at the start-up and slow down phases of operation of the turbocharger, the flow being stopped, or reduced, when the turbocharger has reached normal operating speeds.

Claim (Index 12):
A gas bearing system as claimed in  claim 11 , wherein a plurality of grooves are spaced circumferentially about the journal surface for dynamically generating a layer of pressurised gas in the gap, the grooves each having a leading edge, a trailing edge, and a bottom surface, wherein the grooves are arranged in two rows axially spaced apart by a central land portion, each groove having an inner edge proximal to the land portion and an outer edge distal from the land portion, the inner edge being offset circumferentially behind the outer edge relative to the intended direction of rotation of the journal surface.
