Abstract
A ventilating system for a motor vehicle comprises an air mixing and filtering assembly including a housing defining an air mixing chamber, the housing including a first air inlet port for conducting into the air mixing chamber air from the external environment, a second air inlet port for conducting from the passenger compartment of the motor vehicle air to be recirculated and an outlet port for conducting a composite air stream to the passenger compartment. The assembly includes a filter disk which is pivotably mounted to the housing, the filter disk simultaneously serving as a means for setting the proportions of external air and recirculated air. The filter connection piece forms a part of the housing defining the air mixing chamber.
