Beschreibung
Zusammenfassung:	A turbine wheel for a continuous-flow machine includes a centrally arranged hub with circumferentially arranged blades and a pressure equalizing channel. The hub is configured to enclose a cavity, and a resulting principle axis of inertia of the turbine wheel coincides with an axis of rotation of the turbine wheel. The pressure equalizing channel is configured to fluidically connect the cavity to at least one axial end face of the hub and to an environment of the turbine wheel. A diameter of the pressure equalizing channel is smaller than a diameter of the cavity. In one embodiment, the turbine wheel is for an exhaust gas turbocharger.
