Abstract

A fresh air system for supplying combustion chambers of an internal combustion engine with fresh air may include a housing, through which at least one fresh air path passes, and a flap mechanism, which includes at least one flap adjustably mounted on the housing. The flap may be rotatably adjustable between a closed position, in which the flap closes off the fresh air path in a fluid-tight manner and an opened position, in which the flap opens the fresh air path for fresh air to flow through. The flap mechanism may include a spring-elastic preload element, which supports itself on the housing and preloads the flap against at least one of the opened position and the closed position.
