Abstract

An exhaust gas valve device for an internal combustion engine includes an actuator, an actuator housing, a valve rod configured to be moved in a translational direction via the actuator, a control body arranged on the valve rod, a flow housing comprising laterally delimiting walls, a valve seat arranged in the flow housing, and a shielding element. The valve seat is configured to have the control body be lowered onto and lifted off of the valve seat. The shielding element comprises a base which comprises an opening configured to have the valve rod extend therethrough. The shielding element is configured to extend from the actuator housing into the flow housing, to have a pot shape, and to radially extend to the laterally delimiting walls of the flow housing.
