WHIRL SPRAY NOZZLE

摘要

A spray nozzle for producing a hollow conical liquid spray having a body formed with a cylindrical whirl chamber having a tangentially disposed liquid inlet passage and an orifice cap removably mountable at the end of the whirl champ bier formed with a spray discharge orifice of the desired configuration. The nozzle body includes an upstanding post concentrically disposed within the whirl chamber for guiding pressurized liquid in a tangential direction about the whirl chamber, and the post has a recessed upper end for receiving the air core of whirling liquid within the chamber to retain the proper axial position of the air core and to prevent air core damage to the nozzle body.
