1. A turbine (10) for an exhaust gas turbocharger, comprising:
a turbine housing (12) which has at least two flow paths (14, 16) through which exhaust gas from an internal combustion engine is flowable and which are fluidically separated from one another by a partition wall (26) of the turbine housing (12);
a turbine wheel (24) disposed in the turbine housing (12) and drivable by the exhaust gas;
a bypass channel (32) via which the turbine wheel (24) is bypassable by at least a part of the exhaust gas;
a through-flow opening (34) which is formed in the partition wall (26) and via which the at least two flow paths (14, 16) are fluidically connected to one another; and
a valve element (36) which is adjustable between a closed position closing the bypass channel (32) and the through-flow opening (34) and an open position releasing the bypass channel (32) and the through-flow opening (34) at least in a region, wherein the valve element (36) has a flow channel (44) penetrating the valve element (36) and through which the exhaust gas is flowable;
wherein in the closed position the through-flow opening (34) is completely closed by the valve element (36);
wherein in the closed position, a fluidic connection between the at least two flow paths (14, 16) created by the flow channel (44) is prevented such that that the at least two flow paths (14, 16) are not fluidically connected to each other via the flow channel (44) in the closed position;
wherein in the open position, the valve element (36) releases a first partial region of the through-flow opening (34) and projects into a second partial region of the through-flow opening (34) directly adjoining the first partial region and thus is disposed in the second partial region, wherein the flow channel (44) is disposed in a part of the second partial region, whereby the flow channel (44) is a fluidic connection between the at least two flow paths (14, 16) provided in addition to the released first partial region and the exhaust gas is flowable through the released first partial region and the flow channel (44) and thus the part of the second partial region.
