Abstract

A fresh air supply device for an internal combustion engine may include a housing and a flap arrangement arranged in the housing. The flap arrangement may include at least one flap for controlling a fresh air flow through a fresh air path to a respective cylinder of the internal combustion engine. The flap arrangement may include a common actuator shaft connected to the at least one flap in a torque-proof manner and mounted rotatably about an axis of rotation in a plurality of bearings of the flap arrangement. The actuator shaft may have at least one actuator shaft section in which the actuator shaft has a right-angle bend configured to interact with a stop present on the housing for limiting rotational movement of the actuator shaft.
