The nozzle (10) includes a top member (12), a base member (14), and a discharge orifice (32) defined therebetween. A rotatable external upper collar (16) controls the radius of the pattern, an internal helix member (22) controls the arc of the spray pattern, and an internal flow adjustment screw (20) and an optional rotatable external lower collar (18) control the flow of the nozzle (10). <IMAGE></p> |
