Air outlet

The air jet has air flaps (4, 5) on axis pins (19), a coupling member (3) for the air flaps, an undercut annular inner casing (2) with an insertion receiver (15) for the axis pins, and an annular outer casing (1) able to rotate relative to the inner one. The partly overlapping air flaps form a closed circuit and may have fittings (20) on the rear for pins (18) on the coupling member.
