发明名称 An improvement in a controlled irrigation device for plants
摘要 A container (1) and distributor of water is internally provided with a bath (3) pivoted in such a way as to empty when full. A device comprising a floating piston (44) situated inside a chamber (41) enables water delivery rate to the bath (3) to be regulated by varying a water head contained in the chamber (41), and an outlet opening (43) in the chamber (41) conducts water into the bath (3). A rod (47), insertable in the outlet opening (43), prevents a build-up of residues therein deriving from impurities in the water, such that the outlet opening (43) does not become blocked or obstructed. <IMAGE>
