Abstract: A turbocharger is disclosed, which includes a bypass valve device with a valve element having a shaft movably connected to a valve element support, a spindle rotatable in a bearing bush to one end of which an adjusting lever is attached, and an actuator to actuate the adjusting lever. A spring element is arranged in at least one of the following positions: (A) a 1st position in the region of the connection between the valve element and the valve element support, in which position the valve element shaft passes through the spring element, and (B) a 2nd position between an end face of the bearing bush, and a spring element abutment, fixed to the spindle, in which position the spindle passes through the spring element, wherein the spring element is designed such that the maximum force applied by the actuator for a movement of the valve element is 600 N.

Abstract: Turbocharger provided with a bypass valve device comprising a valve element having a shaft movably connected to a valve element support, with a spindle between the valve element support and an adjusting lever extending transversely to the spindle, and an adjusting lever actuating element pivotably connected to the adjusting lever; an annular spring element is provided in at least one of a first position between the valve element and the valve element support and a second position between the adjusting lever and the adjusting lever actuating element, the spring element comprising at least one annular spring steel disc with a bead being configured and dimensioned so as to minimize play between the valve element and its support or between the adjusting lever and its actuating element.
