Two-substance fan-jet nozzle has cylindrical chamber in front of mixing chamber and which changes into mixing chamber through co-axial connecting hole of smaller diameter

摘要

The nozzle housing(1) has a cylindrical chamber(15) in front of the mixing chamber(11) and which changes into the mixing chamber through a co-axial connecting hole(16) of smaller diameter. A polygonal profile(17) with a co-axial feed hole(18) for fluid medium is fitted in the cylindrical chamber, and the slot(24) remaining between the polygonal profile and cylindrical chambers serves as the co-axial feed of gaseous medium. The polygonal profile on the side facing the mixing chamber has tubular extension(20) which protrudes into the connecting hole.
