Abstract

A control device of an exhaust gas-conducting section of a turbocharger includes a pivotable closing device with a closing element and an element lever. A first element portion thereof opens and closes a first flow cross-section of a flow connection and a second element portion opens and closes a second flow cross-section of a bypass duct of the exhaust gas-conducting section. The element lever includes a lever end portion engaging into a cavity of the closing element. A holding element is fixedly connected to the closing element. The lever end portion includes a first contact surface and, axially spaced apart, a second contact surface. The first contact surface includes an axially-extending first partial surface and a radially-extending second partial surface connected to one another by a third partial surface. The partial surfaces are designed to be able to effect contact with the closing element.
