Distributing device for heating and ventilation systems of motor vehicles

摘要

The invention relates to a distributing device for heating and ventilation systems of motor vehicles, with a cylindrical distributor housing which is supplied by a mixer chamber via a radial inlet opening and has outlet openings branching radially therefrom to connected distribution ducts, and has a double-flap butterfly which is mounted rotatably therein and comprises two essentially rectangular, flat butterfly flaps which determine the distribution of air into the various ducts depending on the rotational position of the double-flap butterfly and with their edges cooperate with the distribution housing in a sealing manner via flexible sealing strips. In the case of a distributing device of this kind, the double-flap butterfly (11) comprises two butterfly flaps (12 and 13) which are parallel to each other and lie at a different distance from and on opposite sides to the imaginary swivelling axis (10). <IMAGE>
