Abstract:
Filtering element for hose fittings of irrigation systems, said filtering element comprising a rigid tubular body at least partially filled with filtering material and having a first end and a second end respectively connectable to a first and to a second terminal of a fitting, a transversal septum with through holes inside said tubular body acting as a cut-off element for said filtering material, and an annular packing inserted inside the tubular body in order to compress the filtering material against said septum, said septum being in a substantially median position with respect to the tubular body, said first end being a cylindrical portion provided with an internal thread, and said second end being a cylindrical portion provided with an external thread, said first terminal being composed of a hollow cylindrical body of rigid plastic material with an externally threaded end, coupled by make up to said first end of the filtering element, and the other side being provided with a row of longitudinal lamellae spaced circumferentially, inside of which a hollow cylinder extends, on which a flexible pipe can be applied, that is afterwards blocked by tightening of a nut screwable on an external threaded portion of said other end of the cylindrical body, in such a way that the lamellae flex and seam fold the pipe, said second terminal being composed of a first hollow cylinder of rigid plastic material with an internal threaded end, couplable by make up to said second end of the filtering element, said first cylinder in its turn being coupled on the other end to a second hollow cylindrical body, said second cylindrical body comprising an end coupled to said first cylinder and the other end provided with a row of longitudinal lamellae spaced circumferentially, inside of which a hollow cylinder extends, on which a flexible pipe can be applied that is then blocked by tightening with a nut screwable, on one external threaded portion of the second cylindrical body, in such a way that the lamellae flex and seam fold the pipe.
