Abstract: A heating and ventilating apparatus for the cabin or passenger compartment of an automotive vehicle includes a cold air transmission branch and an air heating branch, communicating with each other through a mixing zone and leading respectively to a de-icing port for the windshield of the vehicle, aerators or cabin vents at the level of the fascia panel, and lower outlet ports in the lower part of the cabin. A direct guide duct is arranged with its inlet penetrating partly into the outlet of the air heating branch, and with its outlet opening in the vicinity of the de-icing port, which allows warm air coming from the air heating branch to be mixed with the pre-mixed air coming from the mixing zone.

Abstract: This apparatus includes a housing defining within it a first conduit having at least one internal bulkhead extending partially within a distribution chamber and at right angles to the pivot axis of a distribution valve so as to define at least two adjacent air outlets. The housing also defines within it a second conduit having a further air outlet. The distribution valve comprises vanes which are offset axially and circumferentially from each other, for selectively controlling the distribution of air through the outlets of the first conduit, together with a vane for controlling the distribution of air through the outlet of the second conduit.
