Compressor wheel of a radial compressor of an exhaust-gas turbocharger

An exhaust-gas turbocharger (3) having a radial compressor (2) including a compressor wheel (1) having a hub (8);

• and two blade rows (9, 10) arranged on the hub (8) including an inducer blade row (9) comprising a plurality of inducer blades and an exit blade row (10) comprising a plurality of exit blades, the blade rows cooperating for inducting air in axially, accelerating it centrifugally, and discharging air radially outward, wherein the number of inducer blades (11) of the inducer blade row (9) is equal to the number of exit blades (12) of the exit blade row (10), each inducer blade (11) cooperating with an exit blade (12) to form a blade pair, wherein each inducer blade (11) of the blade pair and each exit blade (12) of the blade pair has a leading edge (13, 14), a trailing edge (15, 16), a pressure side and a suction side, wherein a spacing (D) is provided between the trailing edge (15) of the inducer blade (11) of the blade pair and the leading edge (14) of the exit blade (12) of the blade pair as viewed in the inflow direction (A), and the exit blade (12) of the blade pair is advanced in the direction of rotation relative to the inducer blade (11) of the blade pair, and wherein all air flowing through said spacing (D) flows from the pressure side of the inducer blades to the suction side of the exit blades.
