Abstract (en)

[origin: WO2009156444A1] A spraying apparatus (19) for an agricultural field sprayer (10) is proposed. The spraying apparatus (19) comprises a spraying boom (20), at least one spray line (32) disposed on the spraying boom (20), and a plurality of outlet openings (36) disposed along the spray line (32) for spraying fluid, said openings being connected to an inlet opening (66, 76) of a spray nozzle body (40, 70) by way of a connecting piece (38). In order to improve the flow condition of such a spraying apparatus (19), it is proposed to design the connecting piece (38) as a valve housing and to provide it with an inlet opening (44) and an outlet opening (46), which can be closed by a valve control means, for spraying fluid, wherein the inlet opening (44) and outlet opening (46) of the connecting piece (38) are disposed opposite of each other, and the spraying fluid flows through outlet opening (46) in the same direction of flow as the inlet opening (66, 76) of the spray nozzle body (40, 70).
