摘要
The invention provides a radial compressor for an exhaust gas turbocharger, in particular an internal combustion engine, as well as an exhaust gas turbocharger with such a radial compressor. The invention further relates to a method for operating such a radial compressor. The radial compressor for an exhaust gas turbocharger comprises a housing having an axial inlet channel and a radial outlet channel which at least partially surrounds a compressor chamber, wherein a recess is arranged in the housing on the inlet channel side, a compressor wheel arranged in the compressor chamber for conveying and compressing a gas from An inlet channel to the outlet channel, means for adjusting the inner housing contour, comprising: an axially displaceable housing insert, which is arranged in the compressor chamber in a region between the housing and the compressor wheel, a hub which rotatably supported by a recess in the recess around the inlet channel is a piston which is arranged between the hub and the housing insert.
