Claim:
1. A radial compressor for an exhaust gas turbocharger of an internal combustion engine comprising: a compressor housing including an axial inlet channel and a radial outlet channel, wherein the compressor housing at least partially surrounds a compressor space; a compressor wheel arranged in the compressor space for delivering and compressing a gas, wherein the compressor wheel includes an axial inlet side facing the inlet channel, a radial outlet side facing the outlet channel, and an axial wheel surface contour extending from the inlet side to the outlet side; an adapter element substantially designed sleeve-like, the adapter element axially insertable into a fastening section provided on the compressor housing proximate to the axial inlet channel and fixed in a predetermined axial fixing position; and wherein the adapter element having a first axial face end, which in the predetermined axial fixing position faces the compressor wheel, includes a surface contour at least in sections formed substantially complementarily to the axial wheel surface contour, wherein axially moving the adapter element in the fastening section in a non-fixed state of the adapter element adjust a gap width of a passage gap axially formed between the adapter element and the compressor wheel along the axial wheel and adapter element surface contours; wherein the fastening section includes an internal thread and the adapter element includes an external thread that is complementary thereto, wherein the adapter element is moveable relative to the fastening section in the axial direction via the internal and external threads.
