Abstract
A twin-fluid atomizer including upper and lower plates connected to each other by the use of bolts; gas supply pipes each provided to the side of the upper plate; a liquid delivery tube defining an orifice and fixed to the top of the upper plate by the use of a bolt; and a connector body fixed to the lower plate and the outer wall of the orifice of the liquid delivery tube, thus defining an annular gas supply channel. The lower plate has an interchangeable connector stem attachable to the connector body and rotatable via cogs formed on the connector stem. The orifice of the liquid delivery tube and connector forming an annular gas flow passage have outlets with a plane or oblique cross section respectively, and the plane or oblique cross section of each outlet is adjusted and/or rotated to provide a symmetric or asymmetric spray pattern. A bushing interposed between the liquid delivery tube and the upper plate to adjust the length of a protrusion of the liquid delivery tube.
