Abstract
A gas bearing and shaft assembly includes complementary sets of guiding surfaces formed on the gas bearing and the shaft being mutually spaced apart defining bearing gaps therebetween, at least one guiding surface of each of the sets being a porous gas passage surface, a thin-porous layer adjoining the gas passage surface, a component having a given region disposed upstream of the gas passage surface in flow direction of gas fed under pressure through the component to the gas passage surface and the component having other porous gas-permeable regions, the gas passage surface and the thin porous layer together being denser than the other gas-permeable regions of the component producing a pressure drop at the thin porous layer being substantially greater than at the other gas-permeable regions, and gas outlet paths in communication with the bearing gaps within the bearing.
