Abstract

L'invention concerne un émetteur pouvant être installé dans un système d'arrosage fonctionnant par intermittence. Selon l'invention, il comprend un logement 1, 6 formant une paroi d'entrée ayant un orifice d'entrée 10, pouvant être connectée au système d'arrosage, et une paroi de sortie lui faisant face ayant un orifice de sortie 4, les parois étant jointes périphériquement et scellées ensemble pour définir une chambre; un disque d'émetteur flexible normalement essentiellement plat 15 est interposé entre les parois d'entrée et de sortie, avec un moyen de retenue 14 faisant corps avec lui qui est fixé entre les parties périphériques des parois d'entrée et de sortie. L'invention permet un arrosage sur de larges gammes de pressions d'eau.A transmitter that can be installed in an intermittent sprinkler system is disclosed. According to the invention, it comprises a housing 1, 6 forming an inlet wall having an inlet port 10, which can be connected to the sprinkling system, and an outlet wall facing it having an outlet port 4, the walls being peripherally joined and sealed together to define a chamber; a normally substantially flat flexible transmitter disc 15 is interposed between the inlet and outlet walls, with retaining means 14 integral with it which is secured between the peripheral portions of the inlet and outlet walls. The invention allows spraying over wide ranges of water pressures.
