Abstract

L'invention concerne un robinet de minutage. Il comprend un corps qui présente des orifices d'entrée 11 et de sortie 12 entre lesquels l'ecoulement est commandé par une soupape 17, et un reservoir 13 communiquant avec l'orifice d'entrée par un moyen de soutirage réglable, une paroi 14 du réservoir étant flexible et accouplée par une tête 71 et une tige 70 à la soupape 17, de sorte que la pression engendrée dans le réservoir par le liquide soutiré qui y arrive ferme la soupape 17 lorsqu'une différence de pression préfixée apparaît entre le réservoir et l'orifice d'entrée ; le temps nécessaire à l'établissement de cette différence de pression est déterminé par ajustement du moyen de soutirage. Application, par exemple, à la commande d'un dispositif d'arrosage.
