Abstract (en)

[origin: EP0329498A1] Method brought about by a weak flow of air or of fluid blown or pulsed at high speed through a nozzle (3) at the centre of the duct (1) in the desired direction of circulation. Application examples are: - method for extraction of air by blowing in the centre of the duct (1), which is open on the outside, and close to the outlet, of a weak flow of air at high speed in the direction of extraction; - regulating blowing method for conditioned air by virtue of a weak flow of air blown at high speed in the centre of the duct (1); - method for moving delicate fluids, for example for the extraction of exhaust vapours in condensation boilers. <IMAGE>
