A plurality of circumferentially spaced teeth are positioned in a predetermined manner on the end of a pattern-forming sleeve for a liquid discharge nozzle. Each of the teeth is provided with a stream-deflecting surface which is disposed to deflect portions of the discharge stream angularly into intercepting relationship with each other to increase the liquid particle breakup in the stream and improve the uniformity and homogeneity of the stream pattern.
