Abstract

a. Dispositif d'arrosage rétractable. b. Il comprend une enveloppe cylindrique dans laquelle est montée une tige coulissante percée d'un canal longitudinal central et dont l'une des extrémités porte un piston plein dans la surface d'enveloppe duquel a été usiné un canal annulaire qui, au moyen d'ouvertures radiales, est relié au canal central de la tige, cependant que l'extrémité supérieure de l'enveloppe cylindrique est reliée à un circuit d'eau qui commande la rétraction de la tige coulissante, tandis que son extrémité inférieure est raccordée par un conduit d'alimentation au réseau de distribution d'eau pour l'arrosage, caractérisé en ce que, à l'extrémité supérieure du cylindre, sous l'ouverture du réseau d'eau qui commande la rétraction de la tige coulissante sont disposées, à deux niveaux différents, des ouvertures qui sont isolées extérieurement par un manchon annulaire rigide qui forme une chambre annulaire extérieure reliant les ouvertures du niveau inférieur aux ouvertures du niveau supérieur, ouvertures dont l'axe s'étend coaxialement au canal annulaire du piston. c. Installations d'arrosage des cultures agricoles et autres.
