Abstract

An exhaust gas guide section for an exhaust gas turbocharger, with a first spiral channel (4) and a second spiral channel (5) for the inflow of a turbine wheel which is rotatably accommodated in the through-flow exhaust gas guide section, wherein a through-flow opening (10) is provided between the first spiral channel (4) and the second spiral channel (5), which is formed for inducing an overflow of exhaust gas from the first spiral channel (4) into the second spiral channel (5) and vice versa, and wherein the through-flow opening (10) comprises a movable valve (9′) for opening or closing of the through-flow opening (10). According to the invention, the valve (9′) is configured to degressively open a first flow cross section (11) of the through-flow opening (10).
