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.
