Embodiment Construction

[0024] The control device 1 of an exhaust gas turbocharger according to the prior art, not shown in detail, is constructed as shown in FIG. 1 . The exhaust gas turbocharger has a flow-through exhaust gas guide section, not shown in detail, through which a fluid, usually exhaust gas, flows during operation of the exhaust gas turbocharger. Exhaust gases are generally combustion products of internal combustion engines not shown in detail. Such a control device is known under the term wastegate device.

[0025] The exhaust gas turbocharger is assigned a flow-through air guide section, not shown in detail, and a bearing section, not shown in detail, positioned between the exhaust gas guide section and the air guide section, wherein the bearing section is A rotor arrangement not shown in detail is accommodated rotatably in the . The rotor arrangement has a compressor wheel (not shown in detail) and a turbine wheel (not shown in detail), which are connected to one another in a rota...

Abstract

The invention relates to a control device for an exhaust gas turbocharger, the control device having an exhaust gas guide section that can flow through, the exhaust gas guide section having a bypass channel for bypassing the exhaust gas guide a turbine rotatably arranged in the segment; and an adjustment arm (3) for receiving a valve element (2) arranged to open or close the flow cross-section of the bypass passage, wherein The adjusting arm (3) is accommodated movably in the exhaust gas guide section, and a spring element (14) is provided therein for at least securing the positioning of the valve element (2) on the adjusting arm (3) . According to the invention, the spring element (14) is designed in a radially slidable manner for reducing the adjusting force.

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 publication DE 10 2012 101 322 A1, a control device for an exhaust gas turbocharger with a turbine is known, wherein the turbine has a flow-through exhaust gas guide section and a bypass channel, the bypass channel being The purpose is to bypass the exhaust gas flow around the turbine which is arranged in the exhaust gas guide section. The adjustment device includes a valve element for closing the bypass passage, and an adjustment arm, which accommodates the valve element. The adjusting arm is rotatably mounted in the exhaust gas guide section. The valve element is secured on the adjusting arm by means of a spring element in order to avoid noise during operation of the exhaust gas turbocharger. [0003] The problem is that the exhaust gas turbocharger is subject to te...
