| 摘要 |
A spray nozzle assembly having a spray tip formed with an elongated, cylindrical chamber communicating with the liquid supply and being formed with a crossslot 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 transverse to the axis of the chamber, and a pocket extending downstream of the deflector surface. In one embodiment, the spray tip has a preorifice substantially smaller in diameter than the chamber adjacent an upstream end thereof, in another embodiment, the chamber is disposed with its 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 spray tip has a wear resistant metal insert.
