摘要

Title: Agricultural sprayer and its control method Sprayer (1) for distributing liquids, in particular for agricultural use, comprising at least one spray nozzle (4) for spraying the liquid and a mixer (15) with a mixing chamber (16) , having at least a first inlet (20, 21) for a carrier liquid (TF), at least two second inlets (17, 19) for different active agents (A, B, C) and at least one outlet (22) connected to the spray nozzle (4); a controlled valve (23, 27) is associated with each inlet (17, 21). An installation (28) controls the valves (23-27) for a use in accordance with that determined, by pulse width modulation so as to obtain a constant volume flow in the outlet independently of the actuation of the valves (23-27 ).
