Abstract:
A ventilation module comprising a shell housing (15, 8, 77) accommodating a motorized fan unit (2), an air inlet flap for letting air into a turbine and an actuating mechanism adapted to actuate the air inlet flap, the motorized fan unit (2) comprising at least one turbine (16, 73a, 73b) driven in rotation by an electric motor about a central rotational axis (Zâ€²Z), the shell housing (15) being coupled to at least one air intake (11, 12) and outlet (13) formed in an outer casing (10), incoming air being sucked in by the turbine (16) through at least one central orifice (&OHgr;1,&OHgr;2) formed in the shell housing (15), wherein the air-inlet flap (17, 27, 57 to 59, 72) extends on either side of the shell housing (15) and is driven in rotation by the actuating mechanism (75, 79, 79â€², 90) about an axis (Vâ€²V) passing through a space delimited by the shell housing parallel to the rotational axis (Zâ€²Z) of the turbine (73a, 73b), and the housing shell being formed of detachable parts, said detachable parts being dimensioned such that removal of one of said detachable parts facilitates removal of said motorized fan unit through a clearance between said remaining part of said shell housing and said air inlet flap.
