An exhaust gas-driven turbocharger (1) exhibits an adjustable radial turbine (2) which powers a compressor (3) by way of a common shaft (4), whereby a turbine housing (5) designed with a multiplicity of scrolls surround the turbine wheel (6) and exhibits at least two afflux ports (7a, 7b) annularly

An exhaust gas-driven turbocharger (1) exhibits an adjustable radial turbine (2) which powers a compressor (3) by way of a common shaft (4), whereby a turbine housing (5) designed with a multiplicity of scrolls surround the turbine wheel (6) and exhibits at least two afflux ports (7a, 7b) annularly encompassing the turbine wheel (6), whose outlets (8a, 8b) at least partly surround the wheel approach (9) of the turbine wheel (6) and which are at an axial distance from one another. An annular, axially displaceable coupler (15) is provided for opening and closing the outlet (8a, 8b) of at least one afflux port (7a, 7b), so that the boost pressure of the turbine can be influenced thereby.

The radiation apparatus of claim 10, wherein the elastic member, a leaf spring, comprises a pressing end and a forcing end, the neck of the fixing member passing through the elastic member between the pressing end and the forcing end, after the pulled portion being pulled, the pressing end and the pulled portion moving at the same time, the forcing end and the body rotating together, and the forcing end pressing the body for disassociating the absorbing member. 12. The radiation apparatus of claim 11, wherein the elastic member comprises a hole for the neck of the fixing member to pass through. 13. The radiation apparatus of claim 10 further comprises a sleeve moveably mounted to the neck of the fixing member passing through the disassociating flake, and the sleeve and the head of the fixing member clipping the elastic member. 14. The radiation apparatus of claim 13, wherein the absorbing member comprises a screw hole, the neck of the fixing member comprising an outer screw thread, the sleeve comprising an inner screw thread corresponding to the outer screw thread for combining the fixing member and the sleeve. 15. The radiation apparatus of claim 10, wherein the disassociating flake further comprises a hollow for the neck of the fixing member to pass through. 16. The radiation apparatus of claim 10, wherein the fixing member is a screw.
