Air vent for ventilation system of motor vehicle e.g. railway vehicle, has air duct, and device for influencing air flow, where common maximum cross section of air duct flows in all operation cases and has spherical or rectangular shape
The vent has an air duct (1), and a device for influencing air flow. The device is formed in such a manner that a directed, steam-shaped air outlet and a diffuse air outlet are enabled in two operation cases, and constantly adjustable operation cases lying between the operation cases are enabled. A common maximum cross section of the air duct flows in all operation cases and has a spherical shape or rectangular shape. The device has air directing units (3) that are swivelably supported around an associated axis. An independent claim is also included for a method of controlling air discharge of an air vent.
