A supercharging device (), having: a housing () which has a longitudinal axis (L); at least one housing inlet () which leads into the housing (); at least one housing outlet () which leads out of the housing (); at least one compressor wheel () which is arranged in a compressor chamber () and which is driven by a motor shaft () and which is arranged between the housing inlet () and the housing outlet () of the housing () as viewed in the flow direction, and at least one bypass duct () which is integrated in the housing () and which connects the housing inlet () to the housing outlet () so as to bypass the compressor chamber (). The bypass duct () has a self-adjusting valve (). The housing inlet () and the housing outlet () are formed as an axial inlet and an axial outlet respectively.

Supercharging device for a combustion engine

An exhaust-gas turbocharger, preferably for a passenger vehicle, including a turbine having a turbine wheel and a turbine housing. A number of S&#x2265;2 of channels are formed in the turbine housing and are intended for guiding the exhaust gas onto the turbine wheel. Each channel directs flow against the turbine wheel over the entire width of the latter, as seen in the axial direction, and over a segment, as seen in relation to the circumferential direction. The turbine wheel has a number of Z&#x2265;10 turbine blades. The turbine blades are defined in the form of main blades and intermediate blades. The intermediate blades, at least at their hub-side ends, do not extend as far toward the turbine outlet, as seen in the axial direction, as the main blades.

Exhaust-gas turbocharger

A compressor wheel () of a radial compressor () of an exhaust-gas turbocharger (), having a hub (); and having two blade rows () which are arranged adjacent to one another on the hub (), a first blade row () forming the leading blade row, and the adjacent, second blade row () forming the trailing blade row, wherein the number of blades () of the first blade row () is equal to the number of blades () of the second blade row ().
