A method for producing a filter (1) for injectors of fuel, oil, solutions, additives and fluids in general, for braking and transmission systems for example, comprises an element (3) made of plastic material and having a tubular shape, open at opposite ends (6, 7), internally hollow (at 4) and having on one wall (32) of its internal cavity (4) a plurality of projections (30) spaced apart from one another, these projections interacting with portions (27) of a filter element (21) of the pleated type associated with this tubular element and capable of filtering the fluid circulating through the latter. Provision is made for the filter element (21) and the tubular element (3) to form a single filter body by being co-moulded, the filter element (21) being incorporated and completely positioned within the tubular element (3), but having portions of filter surface area (24) which are free of this tubular element (3) so as to allow the passage and filtration of the circulating fluid. |
