Abstract
La présente invention concerne un système d'arrosage de plantes qui est particulièrement approprié pour un récipient de culture présentant un réservoir d'eau sous la plante. Le système d'arrosage utilise une soupape de séquence à servocommande pour maintenir le niveau d'eau du réservoir. La soupape de séquence comprend un diaphragme qui est pneumatiquement accouplé à un orifice de commande fixé au réservoir et submergé dans l'eau. Lorsque le niveau d'eau dans le réservoir atteint une limite inférieure, la pression réduite sur un diaphragme l'amène à ouvrir un passage destiné à l'écoulement d'eau d'une source d'eau vers le réservoir. Lorsque le niveau d'eau atteint une limite supérieure, la pression accrue sur le diaphragme l'amène à fermer ledit passage et à fermer l'écoulement d'eau. La source d'eau peut être un réservoir élevé ou un système d'eau sous pression. Un régulateur de pression peut être utilisé pour diminuer la pression d'eau à l'entrée de la soupape de séquence. Une buse régule le débit d'eau dans le réservoir.
