Title: Spray device for spraying liquids, especially for use in farming
Inventor: GOBEL BERND
IPC: B05B15/658
Filed: 2002-04-10
Abstract: A spraying device for spraying liquids for agricultural pur-poses whose respective sprayer valves attached to a common li-quid supply line (6) are at least configured in the form of dual-sprayer-nozzle valve units (10) whose pair of valve chan-nels share a common distributor bore (14) is disclosed. This distributor bore allows connecting the bodies of dual-sprayer-nozzle valve units (10) in one of two positions in order that, provided that they are connected using a pipe-T, they may be arranged either with their valve bores lined up in rows ex-tending 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 ro-tatable 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.
