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 (6) of the nozzle at least one first discharge opening (11) embodied to generate a core stream of gas with supersonic velocity. The central part is surrounded by a more peripheral part (5) containing a number of second discharge openings (13) 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.
