Abstract
The present invention relates to a silenced blowing nozzle for blowing of a static gas medium under overpressure, in particular air, having in a central part ( ) of the nozzle at least one first discharge opening ( ) embodied to generate a core stream of gas with supersonic velocity. The central part is surrounded by a more peripheral part ( ) containing a number of second discharge openings ( ) spaced from each other and from said first discharge opening(s), the said second discharge openings being embodied to generate a gas flow with lower velocity than the core stream, preferably a velocity equal to sonic velocity, which gas flow surrounds the core stream and has the same direction as said core stream.
