ABSTRACT:
A sprayer has a spray pattern which can be varied by the provision of a second fluid flow path which partially negates the spin velocity to produce a spray having a narrow spray cone producing spray. An opening in the spinner probe establishes the second fluid flow path from the discharge passage, and can be selectively opened and closed upon plunger rotation relative to a hollow piston stem.
