TURBINE AND CORRESPONDING EXHAUST GAS TURBOCHARGER

The invention relates to a turbine comprising a turbine housing defining a volute having a substantially annular outlet opening, a turbine wheel, and an adjusting ring, rotatable about the turbine axis, which is arranged in the turbine housing radially between the volute and the turbine wheel, wherein the adjusting ring comprises a flow channel between a radially outer first peripheral opening anda radially inner second peripheral opening, and wherein the outlet opening is fluidically coupled to the turbine wheel by the flow channel. The outlet opening and the first peripheral opening have apath, variable in the axial direction, so that during a rotation of the adjusting ring, the outlet opening and the first peripheral opening are adjusted relative to each other in such a way that an overflow cross section between the outlet opening and the first peripheral opening is variably changeable. 本发明涉及一种涡轮机，所述涡轮机具有：涡轮机外壳，所述涡轮机外壳限定了涡形，该涡形具有基本上环形的出口孔；涡轮；和能绕着所述涡轮机外壳旋转的调节环，所述调节环在所述涡轮机外壳中径向地布置在所述涡形与所述涡轮之间，其中所述调节环包括在径向外部的
