Air distribution device for use in heating, ventilation and air conditioning installation, has two rotating units assembled by pivot connection, such that angular positions of rotating units are established independent of each other

摘要

The device has a rotating part (3A) including two rotating units (17A, 27A) e.g. valves, that liberate respective paths in angular positions of the rotating units and cooperating with a box for obturating the paths in another angular position of the rotating units. The two rotating units are assembled by a pivot connection, such that the angular positions of the rotating units are established independent of each other.
