Abstract

L'invention concerne des perfectionnements aux dispositifs d'épandage à débit asservi. Le dispositif selon l'invention comprend un réservoir, une pompe 3 reliée au réservoir et à une rampe d'épandage 8, une vanne de régulation 6, un opérateur 9 actionné par un régulateur 10 comparant en permanence la pression régnant dans la rampe 8 et une pression proportionnelle à la vitesse de déplacement, cette dernière pression étant fournie par un transducteur 14 transformant ladite vitesse en une pression directement proportionnelle, entre le transducteur 14 et le régulateur 10 étant interposé un circuit correcteur 13. Application notamment à la pulvérisation d'engrais.
