Abstract
A nozzle of an air supply device is accommodated in a hole (17) in a wall (15) of the device, such as to enable the nozzle to be rotated about a first axis extending through the center of the hole, and pivoted about a second axis that extends perpendicularly to the first axis through two engagement points (6a) on the nozzle. The nozzle includes two or more guide vanes or baffles in the form of tongues (2,3) that have rear deflecting parts (2a,3a) of mutually different curvature, and a front, generally flat outflow part (2b,3b). The nozzle also includes a central tongue-holding part (5) which has resilient hook-shaped engagement elements (6a) at opposite ends. The nozzle may also include a third guide vane or baffle (4) that lacks a curved deflecting part. The air flow exiting from the nozzle can be directed in different planes. The invention also relates to an air supply device provided with one or more such nozzles (1).
