Abstract
A control device for an exhaust gas turbocharger includes a closing device with a closing element and an element lever, pivoting around an axis. The closing element is designed to open and close a first flow cross-section formed by a partition wall between two spiral channels in the exhaust gas-conducting section. Additionally, there is a second flow cross-section associated with a bypass duct designed to direct flow around a turbine wheel. The closing element comprises two parts: one for the first flow cross-section and another for the second flow cross-section. The element lever features an arm that fits into a cavity in the closing element. This cavity has an inner surface, and the arm's outer surface matches the cavity's shape but with differing dimensions. The arm's peripheral surface includes multiple distinct sections, enhancing the engagement with the closing element's cavity.
