摘要： The present invention relates to an oil-free turbocharger assembly using an airfoil bearing that may be useful in high speed conditions. The assembly can be cooled easily. A heat-proof coating can also be easily applied to the turbo charger's rotating shaft. In one embodiment, an oil-free turbocharger assembly has a constant distance between a journal portion and a rotating shaft so that the mass of the rotating body can be minimized and the rotating body assembly can have a small moment of inertia. The turbocharger in some embodiments of the invention may be cooled by a refrigerant which improves cooling efficiency. Each part of the rotating body assembly in some embodiments may be individually treated with a heat-proof process so that productivity can be improved.

摘要： A bearing seal for a gas turbine for reducing axial leakage of a working gas of a turbine and for supporting the vertical loads and shear forces efficiently. The seal is disposed on an inner surface of a bearing housing where a rotating shaft is positioned at the center of the bearing housing. The bearing seal includes an elastic porous foil for adjusting leakage of a working gas through the space between the rotating shaft and the bearing housing, wherein a density ratio of the porous foil increases along gas inflow direction. The porous foil is deformed elastically by a dynamic pressure of the working gas leaked around the rotating shaft during rotation of the rotating shaft for making a gap between the porous foil and the rotating shaft.
