Abstract
A fluid nozzle for an air assisted spray device is disclosed, wherein the fluid nozzle may have a nozzle tip therein which is more resistant to fluid abrasion than other portions of the fluid nozzle. In one embodiment, a plurality of nozzle tips are capable of being interchangeably used with a single main body of the fluid nozzle. Thus, replacement nozzle tips can be used when: (a) a nozzle tip effectiveness deteriorates due to wear, and (b) a fluid to be sprayed requires a nozzle tip with a different configuration. Further, in one embodiment, the fluid nozzle of the present invention provides an annular plenum between a recess wall of the main body, and an exterior portion of the nozzle tip. Such a plenum is used to enhance the volume and turbulence within an air chamber of the spray device prior to the air exiting for atomizing the fluid being sprayed. Thus, such enhanced turbulence provides a more uniform air velocity exiting the air chamber.
