• the cartridge 7, 7 ' preferably comprises a porous or fibrous element 16 impregnated with perfume, for example in the form of a liquid or a gel.
• Each orifice 9a, 9b, 9'a, 9'b of the cartridge 7, 7 ' is equipped with a movable valve 10 between an open position of the orifice 9a, 9b, 9'a, 9'b and a closed position of the orifice 9a, 9b, 9'a, 9'b.
• a single valve 10 may optionally be used to open or close the two aforementioned orifices 9a, 9b, 9'a, 9'b.
• Each valve 10 is constrained by an elastic return member 11, for example a helical compression spring, tending to return the valve 10 to its closed position of the orifice 9a, 9b, 9'a, 9'b. In the closed position, the edges of the valve 10 come into sealing engagement on the edges of the orifices 9a, 9b, 9'a, 9'b corresponding.

• Sealing means such as for example that seals 12 of elastomer, are mounted between the orifices 9a, 9b, 9'a, 9'b of the cartridge 7, 7 'and the corresponding orifices 6a, 6b, 6'a , 6'b of the housing 2.
• each pusher 13, 13 ' comprises two branches 14 traversing transversely the fluid circulation channel 3, the end of each branch 14 being intended to bear against one of the valves 10 of the corresponding cartridge 7, 7'.
• Each branch 14 extends along the axis of the orifices 6a, 6b, 6'a, 6'b, 9a, 9b, 9'a, 9'b associated with the corresponding valve 10.
• the pushers 13, 13 ' are displaceable in translation, along the axes of the branches 14, between a closed position of the valves 10 (FIG. cartridge 7) and an open position of the valves 10 (FIG. 3, cartridge 7) in which the branches 14 rest against the valves 10, against the elastic return members 1 1.
• the pushers 13, 13 ' are designed in such a way that a part F2 of the air flow F1 entering the fluid circulation channel 3 can pass directly through said channel 3, without crossing the cartridges 7, 7 '.
• the cartridges 7, 7 ' are mounted and fixed on a spool 15 movable in translation along an axis parallel to the axis of movement of the pushers 13, 13'.
• the housing 2 and the drawer 15 can be integrated for example in the dashboard of the vehicle, the channel 3 opening at an air distribution grid.

• a user can move the drawer 15 to its position illustrated in FIG. Two cartridges 7, 7 'of the same perfume or of two different perfumes can then be fixed on the spool 15. In this loading or replacement phase, the cartridges 7, 7' are hermetically sealed by the valves 10, so that to avoid accidental leakage.

• the management and calculation means and the actuators control the opening and closing of the valves 10, through the pushers 13, 13 '.
• the intensity can be adjusted by means of the rate of opening of the valves 10 of each cartridge 7, T.
• Another useful method is to vary the flow of air F1 entering the fluid circulation channel 3.
• the fibrous or porous element 16 extends over the entire section of the canal
• the fibrous or porous element 16 may extend over only a portion of the U-channel section of the cartridge 7, T.
• the surface of the wick dries, but the heart being wet (loaded with fragrance), the fragrance rises to the surface of the wick by capillarity (until the wick is completely used up.)
• This concept of vaporization of fragrance « by licking "offers a very low pressure drop of the air circuit.
• the air F3 entering the cartridge 7, T could also, not lick the surface, but be forced through the pores or interfiber spaces of said element 16, but in this case the necessary air pressure would be much larger.
• FIG. 4 illustrates another embodiment in which each pusher 13, 13 'comprises two branches 14 whose so-called front ends are intended to bear on the valves 10 of the corresponding cartridge 7, 7' and whose rear ends are interconnected and extended at the rear by a partition 17 perpendicular to the channel 3 and extending over the entire section of said channel 3.
• the partition 17 forces the air to enter the corresponding cartridge 7, T.
• the air flow can pass through branches 14 which, they do not extend over the entire section of the channel 3.
• Such an embodiment therefore makes it possible to considerably increase the flow of air F3 passing through a cartridge 7, 7 'whose orifices 9a, 9b, 9'a, 9'b are open by the corresponding pusher 13, 13'.
• FIG. 5 represents another embodiment, in which each cartridge 7, 7 'has only one orifice 9, 9', arranged facing a single corresponding orifice 6, 6 'of the housing 2 opening into the channel 3.
• the valve 10 is returned to its closed position by an elastic return member 1 1 and is moved into its open position, by means of a pusher 13, 13 '.
• the cartridges 7, 7 'do not comprise a channel U but internal volumes each comprising, as previously, a fibrous or porous element 16 soaked in perfume.
• control means 13 or 13 ' may comprise within the channel 3 a partition 17 which, when the control means is actuated to open the valve 10, prevents the air to walk directly along F2 (in channel 3), and force the air to walk totally or partially along F3 (in the cartridge 7 or 7 ').
