<p>The ventilation system box (2) contains a series of air pipes (4, 6, 8), fitted with valves (10, 12, 14). Movements of the control element (20), which presents a series of surfaces (28, 30, 32), each carrying a shaped device (34, 36, 38), are transmitted to activate the valves. At least one of the surfaces of the control element is not parallel to the others and carries a shape to drive the kinematic chain, which activates the valve (14), which is not parallel to the other valves.</p> |
