Regulating device for an exhaust turbocharger

A regulating device for an exhaust turbocharger, wherein the regulating device (1) is received in an exhaust gas conducting section of the exhaust turbocharger, through which a fluid can flow, and wherein with the aid of the regulating device (1) a fluid flow onto a turbine wheel rotatably received in the exhaust gas conducting section can be conditioned, wherein a through-flow opening formed in the exhaust gas conducting section is to be opened and closed with the aid of a valve element (2) of the regulating device (1), and wherein the valve element (2) is arranged on a pivot arm (4) of the regulating device (1) which can be pivoted about an axis of rotation (17), and wherein the valve element (2) has a valve body (5) which comprises an insert element (7) which is received predominantly in a hollow space (29) of the valve body (5) and which is operatively connected to the pivot arm (4) in particular with the aid of a lever arm (3), and wherein the valve element (2) has a sealing surface (22) for avoiding a leak in a closed position of the regulating device (1),

• characterized in that, in order in particular to reduce secondary torques acting upon the valve element (2) during operation, a connection is formed between the pivot arm (4) and the valve element (2) in or at least close to a center of gravity of an effective valve element body (31) of the valve element (2), wherein the effective valve element body (31) comprises the valve body (5) and a cover element (6) which, in order to avoid an inflow of a fluid into the valve body (5), is configured to close the hollow space (29) of the valve body (5), wherein the cover element (6) is configured to cover the insert element (7) at least partially.
