Abstract
Un movimento ascendente di un otturatore (12) tende a chiudere un passaggio di regolazione (13) che comanda la portata da regolare, questo movimento essendo azionato da uno stantuffo (15) sotto l'effetto di una caduta di pressione motrice che cresce con questa portata. Secondo l'invenzione, questo otturatore è costituito da un tubo (12) il cui bordo superiore (12b) limita questo passaggio di regolazione (13), la caduta di pressione motrice comparendo al passaggio di questa portata intorno a questo stantuffo (15).L'invenzione si applica in particolare all'irrigazione.(fig. 1).
