Abstract

Improvements introduced in filters intended mainly for filtering natural irrigation waters of cultivated fields, characterized by including: - a body that communicates with the outside through two lateral openings and a drainage opening, said drainage opening being temporarily closed, - a filter element mounted inside the body and delimiting, inside the body, two concentric chambers: . One, the first, which communicates with the exterior, on the one hand, through the temporarily closed opening, on the other hand, through one of the lateral openings, . another, annular in shape, surrounding the previous one, which communicates with the exterior through the other lateral opening; said filter being characterized in that it further comprises: a brush housed inside the first chamber, operable from the outside, the hairs of which sweep the internal wall of the filter element; the liquid that is to be filtered enters the filter through the lateral opening that communicates with the cylindrical chamber and leaves the filter through the lateral opening that communicates with the annular chamber, after the filter element has passed through from the inside to the outside .
