<p>A device for treating a flow of air that is to be sent into the passenger compartment of a vehicle, comprising:
- a supporting casing (12) defining a cooling chamber (18), a heating chamber (20), a distribution chamber (22), a first opening (32) that sets the cooling chamber (18) in communication with the distribution chamber (22), a second opening (34) that sets the cooling chamber (18) in communication with the heating chamber (20), and a third opening (36) that sets the heating chamber (20) in communication with the distribution chamber (22);
- an evaporator (24), housed in the cooling chamber (18), and a heating radiator (28), housed in the heating chamber (20); and
- a mixing valve (45), which is mobile between a first position and a second position, in which in the first position the mixing valve (45) closes the first opening (32) and opens the second and third openings and in which in the second position the mixing valve (45) closes the second and third openings (34, 36) and opens the first opening (32). The mixing valve (45) comprises:
- a control lever (46) having a first end (48) articulated to the casing (12);
- a main flap (50) articulated to a second end (52) of the control lever (46), the main flap (50) having a laterally projecting pin (52) that engages slidably a first guide (56) fixed with respect to the casing (12); and
- a secondary flap (58) having a first end (60) articulated to the main flap (50) and carrying at a second end a laterally projecting pin (62) that engages slidably a second guide (64) fixed with respect to the casing (12).</p> |
