摘要： An exhaust gas turbocharger with an exhaust gas turbine and a radial compressor includes an impeller which pumps air through guide vanes or wedge guide elements into a helical passage. It is proposed that the guide vanes or wedge vane elements be guided for axial displacement in the casing of the radial compressor and be able to be shifted across the pumped stream of the impeller.

摘要： An exhaust-gas turbocharger for an internal combustion engine has an exhaust-gas turbine in the exhaust tract and a compressor in the intake tract, the exhaust-gas turbine and the compressor being connected via a shaft which is supported in a casing of the exhaust-gas turbocharger via at least one bearing. In order to improve the efficiency of the turbocharger, the bearing has a non-contact design, in that, when the exhaust-gas turbocharger is in operation, the shaft is held at a distance from, and so as to be virtually free of friction with, a bearing receptacle fixed to the casing.
