<p>A spray nozzle assembly (11) having a spray tip (20) formed with an elongated, cylindrical chamber (30) communicating with the liquid supply and being formed with a cross-slot (34) which intersects the chamber at a location intermediate the ends thereof for defining a discharge orifice (31), a deflection surface (32) on a downstream side of the discharge orifice (31) for directing liquid in a direction transverse to the axis of the chamber, and a pocket (38) extending downstream of the deflector surface. In one embodiment, the spray tip has a pre-orifice (42) substantially smaller in diameter than the chamber (30) adjacent an upstream end thereof, in another embodiment, the chamber (30a) is disposed with its axis at an angle to the vertical and the cross-slot (34a) extends upwardly in substantially vertical relation for defining a vertical deflection surface, and in still another embodiment the spray tip (20d) has a wear resistant metal insert (72). <IMAGE></p> |
