| 摘要 |
The invention relates to a system for removing pollution from the air in a vehicle passenger compartment, comprising a main pipe (15) carrying air into the passenger compartment (1), a secondary pipe (14) in which the air from the passenger compartment (1) circulates, a tapping providing the connection between said main pipe (15) and said secondary pipe (14), an air-filtration device (11) formed in the secondary pipe (14), upstream of the tapping, and a blower (13) arranged in the portion of main pipe (15) downstream of the tapping. Furthermore, at least one distributor flap (40, 41) is arranged in the main pipe (15) or secondary pipe (14) so as to generate reduced pressure in the secondary pipe (14) downstream of the filtration device (11) such that, by the induced use of a Venturi effect (30), ambient air from the passenger compartment (1) is forced to circulate through the filtration device (11). |
