A wastegate valve device for a supercharging device may include a valve disc, which is connected to an actuator device via a drive train. The wastegate valve device may include at least one damping element arranged between the valve disc and the actuator device. The drive train may have an inner section, which is arranged inside a fluid path of a driving fluid. The inner section may include a spindle arm, which is connected to a spindle and to the valve disc. The spindle may be connected to an operating arm, which is arranged in an outer section of the drive train. The operating arm may be arranged outside the fluid path, and may be connected to an operating rod, which is connected to the actuator device. The damping element may be arranged in a connection region of the drive train. |

1. A wastegate valve device for a supercharging device, comprising:
a valve disc, which is connected to an actuator via a drive train; at least one damper arranged between the valve disc and the actuator; wherein the drive train has an inner section, which is arranged inside a fluid path of a driving fluid, the inner section including a spindle arm, which is connected to a spindle and to the valve disc;
wherein the spindle is connected to an operating arm, which is arranged in an outer section of the drive train, the operating arm arranged outside the fluid path, and is connected to an operating rod, which is connected to the actuator;wherein the damper is arranged in a connection region of the drive train, the operating rod having a coupling member, which is connected to the operating arm, the damper including a sleeve, which surrounds a coupling section of the operating rod and the coupling member, the damper being prestressed against the coupling section via the sleeve in a radial direction and simultaneously against the coupling member; andwherein at least one damping material of the damper is arranged between at least one of the sleeve and the coupling section and the sleeve and the coupling member. |
