Abstract
A quick-disconnect nozzle connection for a spraying tip and a nozzle body. The spraying tip is defined by a cylindrical inlet stem at one end of the tip, an interior fluid passage communicating from the inlet of the cylindrical stem through the tip to an orifice, at least one arcuate section extending radially outwardly from the cylindrical surface of the stem, and a recess formed in each arcuate section. The nozzle body is adapted to be connected to a source of fluid and defines an interior fluid passage, a first cylindrical chamber adapted to receive the cylindrical stem of the spraying tip, a second cylindrical chamber of larger diameter than the first cylindrical chamber and in axial alignment with the first chamber and further adapted to receive each arcuate section of the spraying tip, and retention segments extending radially inwardly over the second chamber, each of the retention segments adapted to matingly engage a corresponding recess in an arcuate section to connect the spraying tip and nozzle body in a locked and precise angular relationship. A spring disposed between the nozzle body and spraying tip maintains the body and tip in the locked relationship. Methods of manufacture for the tip and body are also disclosed.
