Embodiment Construction

[0027] A control device 1 for an exhaust gas turbocharger according to the prior art, not shown in detail, as in figure 1 constructed as shown in. The exhaust gas turbocharger has a flowable exhaust gas guide section, not shown in detail, through which a fluid, usually exhaust gas, flows through during operation of the exhaust gas turbocharger. The exhaust gases are generally combustion products of an internal combustion engine, not shown in detail. Control devices of this type are known by the term wastegate device.

[0028] The exhaust gas turbocharger is assigned an air guide section (not shown in detail) through which flow can flow, and a bearing section (not shown in detail) positioned between the exhaust gas guide section and the air guide section, wherein the bearing section A rotor arrangement, not shown in detail, is rotatably accommodated therein. The rotor arrangement has a compressor wheel (not shown in detail) and a turbine wheel (not shown in detail), which ar...

Abstract

The invention relates to a control device for an exhaust gas turbocharger, the control device having an exhaust gas guide section through which flow is possible, the exhaust gas guide section having a bypass channel to bypass the rotatably arranged a turbine in the exhaust gas conduction section; and an adjusting arm (3) for accommodating a valve element (2) configured to open or close the flow cross-section of the bypass channel, wherein The adjusting arm (3) is accommodated movably in the exhaust gas guide section, and a spring element (14) is provided therein at least for securing the positioning of the valve element (2) on the adjusting arm (3) . According to the invention, the spring element is designed to be held radially and axially by the valve element (2).

Description

technical field [0001] The invention relates to a regulating device for an exhaust gas turbocharger. Furthermore, the invention relates to an exhaust gas turbocharger. Background technique [0002] From the published document DE 10 2012 101 322 A1 a control device for an exhaust gas turbocharger with a turbine is known, wherein the turbine has an exhaust gas guide section through which flow can flow and a bypass channel for the The purpose is to bypass the exhaust gas flow around the turbine arranged in the exhaust gas conduction section. The adjustment device comprises a valve element for closing the bypass channel, and an adjustment arm which accommodates the valve element. The adjusting arm is mounted rotatably in the exhaust gas guide section. The positioning of the valve element on the adjusting arm is ensured by means of a spring element in order to prevent noise and to optimize or reduce wear during operation of the exhaust gas turbocharger. [0003] Problematical...
