Abstract:
Particles ( 23 ) are supplied to a bearing gap of a foil bearing. A step ( 24 ) is formed in a top foil portion ( 12 a 1 ), to thereby generate an air flow from both end portions ( 121  and  122 ) in a direction (N) along a surface of the top foil portion ( 12 a 1 ) and orthogonal to a rotation direction (R) of a shaft ( 6 ) toward a region between the both end portions.

Claim (Index 1):
A foil bearing, comprising:\n a top foil portion having a bearing surface which forms a bearing gap with a shaft to be supported; and a support portion, which is arranged on a back side of the top foil portion, and is configured to elastically support the top foil portion, wherein the foil bearing is configured to support relative rotation of the shaft in a non-contact state with fluid pressure generated in the bearing gap, wherein particles are supplied to the bearing gap, and wherein the top foil portion comprises a fluid control portion which is configured to generate a fluid flow from both end portions of the top foil portion in a direction along a surface of the top foil portion and orthogonal to the relative rotation direction toward a region between the both end portions.
