摘要： At a ventilation plant possessing roof mounted down blow pipes (2) within which an in non-step-wise manner variable ventilation fan (8, 10) is arranged, the lower spreading nozzle is formed of an in upwards direction spring biased horizontal valve plate (14) which is urging to close the exit mouth of the down blow pipe (2). During operation of the ventilator fan (8, 10) the valve plate (14) is pressure influenced downwards depending upon the volume speed of the air whereby a ring shaped nozzle (26) between the valve plate (14) and an overlaying projecting rim (12) of the pipe exit mouth is formed. As the ring shaped nozzle (26) width automatically adjusts itself according to the volume speed of the air this feature can be utilised to safeguard that the radiation speed of the air from the nozzle remains approximately constant, independent of the volume speed, in which way an efficient spreading of the air during different operation conditions can be safe guarded in an extremely simple way.
