An exhaust gas-conducting section of an exhaust turbocharger comprises a duct with a through-flow opening which can be fully or at least partially blocked or released by a closure element of a control device. The closure element is designed as a poppet valve. The closure element can be moved by an actuator can be disposed in a wall of the exhaust gas-conducting section. The closure element has a closure body with an annular section surface on its bottom surface which faces the through-flow opening. The section surface corresponds to an element seat formed in the wall. Its top surface faces away from the bottom surface and is designed in a profiled manner in order to produce a top surface at least partially corresponding to another element seat and/or to achieve flow-optimized circulation.

Control device for an exhaust gas-conducting section of an exhaust turbocharger

The invention relates to a regulating device for a turbocharger. The regulating device () is received in a turbocharger () exhaust gas conducting section () through which exhaust gas can flow, and a fluid flow to a turbine wheel which is rotatably received in the exhaust gas conducting section () can be conditioned using the regulating device (). A flow channel () which is formed in the exhaust gas conducting section () is to be opened and closed using a cover element () of the regulating device (), and the cover element () is arranged on a regulating device () pivot arm () which can be pivoted about a rotational axis (). According to the invention, the cover element () is designed to open and close a flow channel designed as a bypass channel () for bypassing the turbine wheel and/or for opening and closing a flow channel, which is designed as a through-flow opening (), between a first spiral channel () and a second spiral channel () of the exhaust gas conducting section ().
