ABSTRACT:
The construction of a nozzle head for a trigger sprayer apparatus and the constructions of several variant embodiments of fluid spinners that are assembled into the nozzle head facilitate the assembly of the spinners into the nozzle head with fluid swirl chambers of the spinners centered relative to a fluid discharge orifice of the nozzle head. The swirl chamber of each spinner assembly is surrounded by an annular wall and the end face of the annular wall engages against a flat orifice wall surrounding the sprayer discharge orifice thereby sealing the swirl chamber around the orifice. Tangential grooves through the annular wall provide the only path of fluid flow into the swirl chamber.
