Abstract

A Spraying assembly for spraying liquids for agricultural purposes is provided whose respective sprayer valves attached to a common liquid supply line are at least configured in the form of valve housings whose pair of valve channels share a common distributor bore. This distributor bore allows connecting the bodies of valve housings in one of two positions in order that, provided that they are connected using a t-shaped fitting, they may be arranged either with their valve bores lined up in rows extending to the front or rear of the liquid supply line, as well as ahead of or behind the liquid supply line and aligned parallel thereto. Since one embodiment also provides a rotatable pipe-T joint, the dual-sprayer-nozzle valve units may also be arranged beneath the liquid supply line, which yields a large number of opportunities for laying out the sprayer nozzles, in spite of the simple means available for connecting them.
