Abstract

Pour épandre un volume constant de liquide par unité de surface malgré la variation de la vitesse d'avancement, à l'aide d'au moins un organe d'épandage à section constante, on utilise un régulateur de pression de liquide asservi à la vitesse d'avancement et assurant le réglage constant de la pression d'épandage. Le régulateur 4 est asservi au moyen d'un circuit auxiliaire de liquide comportant une pompe volumétrique 47 entraînée à une vitesse de rotation proportionnelle à la vitesse d'avancement et débitant à travers un ajutage dont la loi de variation débit-pression est la même que celle du ou des organes d'épandage. Application, notamment, aux pulvérisateurs agricoles.
