The present patent application relates to an exhaust gas turbine (1) for an exhaust gas turbocharger. A turbine casing (2) surrounds a turbine wheel (3) that is mounted on a rotor shaft (4). The turbine casing (2) has an inlet (5) that is connectable to a source of exhaust gases and an outlet (6). A diffuser duct (7) has an inlet (8), which is connected to the outlet (6) of the turbine casing (2), and an outlet (9). An outer housing (10) encloses the diffuser outlet (9), which outer housing (10) has an outlet (11). A waste-gate valve (12) is arranged to communicate with the source of exhaust gases and selectively pass excess exhaust gases into the outer housing (10). At least one opening (13) is arranged to allow excess exhaust gases to mix with exhaust gases from the turbine (1) within the enclosure provided by the outer housing (10). |
