ABSTRACT:
A system and method for reducing fluid drainage into air passageways of a spray device during disassembly. The present technique provides an internally mountable fluid nozzle having a fluid inlet, a fluid exit, and a converging central passageway extending substantially between the fluid inlet and the fluid exit. Accordingly, the internally mountable fluid nozzle has a relatively small internal volume, which reduces the amount of fluid that can be spilled during disassembly of the spray device. The present technique also provides a section of the spray device having an air passageway with an air exit, and a protrusive fluid passageway with a fluid exit in a protrusive offset position from the air exit. The internally mountable fluid nozzle can be mounted to the section in fluid communication with the protrusive fluid passageway, such that fluid spillage or drainage during disassembly does not flow into the air passageway. A spray formation section also may be coupled to the section, such that an internal cavity of the spray formation section is disposed about the internally mountable fluid nozzle.
