The invention relates to an exhaust gas turbocharger with a manifold-flow casing, in particular a dual-flow casing () and a turbine wheel () which is rotatably arranged within said manifold-flow casing, onto which an exhaust gas flow () may be led via at least one of several flow channels (), and an outlet opening () following said one flow channel () and covering an angle of 180&#xb0; max. about an axis of rotation () of the turbine wheel (), so that a shaft () is rotating which is arranged coaxially and non-rotationally relative to the turbine wheel (), which is supported in a shaft bearing ().

Exhaust gas turbocharger

The invention relates to a control device for a turbocharger, comprising an exhaust gas conducting section through which fluid can flow and which includes a bypass duct for bypassing a turbine wheel that is rotatably arranged in the exhaust gas conducting section, and comprising an adjusting arm () for accommodating a valve element () provided for opening or blocking a flow cross-section of the bypass duct; the adjusting arm () is movably accommodated in the exhaust gas conducting section; furthermore, a flexible element () is provided at least for securing the valve element () in place on the adjusting arm (). According to the invention, the flexible element () is designed to be retained radially and axially by the valve element ().

Adjusting device for a turbocharger, and turbocharger

In an adjustable guide vane mechanism for a turbine, comprising a bearing ring with a plurality of guide vanes rotatably supported on the bearing ring by means of guide vane shafts provided with actuating levers which are engaged by a rotatable ring, the rotatable ring comprises axially spaced radial inner and outer sections with a radially inclined center section joining the spaced radial inner and outer sections, the radially inner section being rotatably supported and the radially outer section extending around the actuating levers and having recesses in which the actuating levers are received for pivoting the actuating levers and the guide vanes upon rotation of the rotatable ring.
