A pump sprayer having a reciprocable hollow piston stem defining a fluid discharge passage, a plunger head mounted on said stem and having a probe extending transversely from said stem, a nozzle cap assembly including a nozzle cap surrounding said probe, said cap having a discharge orifice and means including a spin chamber in communication with said orifice for imparting a spin at a given velocity to fluid to be discharged through said orifice as a fine mist spray of a given discharge spray pattern in a first position of said cap, a fluid path defined between said head and said nozzle cap and extending from said passage to said orifice via said spin imparting means, the improvement wherein: said nozzle cap assembly is hinged to said plunger head for movement of said spin imparting means a given distance away from a free end of said probe to a second position for negating the spin imparted to the fluid for varying the discharge spray pattern, said assembly having a cover plate overlying said plunger head to facilitate the hinged movement between said first and second positions.
