A spray nozzle assembly including a body and a nozzle tip having a ball-shaped mounting end for selected swivel positioning within a socket in the body. The nozzle tip contains a vein for imparting swirling movement to liquid passing through the nozzle assembly such that the discharging liquid has a hollow cone spray pattern. The vein has a pair of liquid flow passageways each having a diameter of at least .22 the diameter of the ball-shaped mounting end of the tip and at least .32 the diameter of the vein for permitting the free passage of liquids with relatively larger solid materials than heretofore possible with comparably sized nozzle elements. To ensure that the vein passageways extend through the vein without the existence of an axial see-through condition, the vein has a chamfered upstream end extending outwardly of the tip.
