摘要

The air vent consists of a duct (10) with its inner surface in the shape of a segment of a sphere between an intake (12) and outlet (14) and having an angle at the centre of at least 90 degrees. The spherical segment of the duct contains an adjustable shutter (20) that moves on two sliders (30) in the form of sectors of a sphere connected to the shutter body by arms (32) controlled by an inner cam mechanism (26) with curved slots (28) and a control element (24).
