ABSTRACT:
The present invention provides a liquid spray gun with several improved features, including (1) non-cylindrical air passageways on air horns included in an air cap portion of a body assembly that provide improved shape and uniformity for the wide elongate stream of liquid formed by the spray gun; (2) the air cap portion of the body assembly being mounted for manual rotation on a nozzle portion of the body assembly between positions defined by stops and retained at those positions by friction; and (3) the body assembly through which passes liquid sprayed by the spray gun being molded of polymeric material and being manually releasable from a metal platform portion of the spray gun through which air is fed to passageways through the body assembly to spray the liquid.
