Abstract
The control device for programmed supply by means of pressure impulses in an irrigation conduit is composed of a floater (572), with an intermittent advancing rotating obturator, and a dosing mechanism (560), capable of determining the emptying of the chamber (538) of said floater, in a period of time not less than the pre-established limit, and is characterized by a closed circuit (612, 604, 538, 630, 626) for a control liquid, into which circuit, the following are inserted: the said chamber (538), with floater (572); a separation lung (608) with membrane (610), placed in communication on one side with the said chamber (538) by means of the dosing mechanism (602), and on the other side in communication with the arrival conduit (620 A), and a hydraulic relay mechanism (626), controlled by the said closed circuit, and capable of controlling an intercepting shutter gate (622) in the conduit (620A, 620B) to be controlled.
