Abstract
A spray nozzle assembly having a spray tip formed with an elongated, axially extending cylindrical chamber communicating with the liquid supply and being formed with a cross slot which intersects the chamber at a location intermediate the ends thereof for defining a discharge orifice, a deflection surface on a downstream side of the discharge orifice for directing liquid in a direction transversed to the axis of the chamber, and a pocket extending downstream of the deflector surface a distance significantly greater than the diameter of the chamber. In one embodiment, the spray tip has a pre-orifice of about one half the diameter of the chamber adjacent an upstream in thereof, in another embodiement, the chamber is disposed with it axis at an angle to the vertical and the cross slot extends upwardly in substantially vertical relation for defining a vertical deflection surface, and in still another embodiment the cross slot is formed with a round that extends beyond the axis of the chamber substantially to the perimeter thereof and has a radius of about twice the diameter of the chamber.
