Abstract

A flow divider, particularly for use in uniformly dividing a single incoming stream of liquid fertilizer into multiple outlet streams. The flow divider features a housing having a bore therein; a distribution sleeve which fits within the bore; and a distribution needle which slides within the distribution sleeve to evenly divide the incoming flow. Flow enters a distribution chamber formed between a tip portion of the distribution needle and the distribution sleeve, preferably flowing over a series of circumferential ribs located on the tip portion, and accelerates through a narrowing, flow-accelerating region between the distribution needle and the distribution sleeve. The flow is then discharged through a series of orifices in the distribution sleeve and out through a series of flow passageways radially arranged around the flow divider. When fluid flow supply is terminated, no pressure is developed and the distribution needle automatically returns to a closed position in which the inlet orifice in the distribution sleeve is closed by the tip portion of the distribution needle, and the outlet flow orifices in the distribution sleeve are closed by means of the body portion of the distribution needle.
