ABSTRACT:
A swirl pressure nozzle with a nozzle body is proposed, in which an inner area is provided, which has a tapered section with a largest diameter and a smallest diameter. The nozzle has an inlet which leads into the section in an essentially tangential manner, which has a diameter, such that a fluid medium can be guided under pressure through this inlet in an essentially tangential manner into the tapered section of the inner area. The section has an axial length and at its end with the smallest diameter leads into an outlet of the nozzle, which has the same diameter as well as a length. The different parameters are in a ratio to each other, that lies in the following ranges:Dp/Doin the range from 0.42 to 1.56;Ds/Doin the range from 3 to 8;the angle of opening (alpha) of the tapered section greater than 60°;Lo/Doin the range from 0.2 to 1.5.
