CLAIMS
1. A filter for Diesel engine fuel, comprising a filtering mass which is contained within an enclosure (2), said mass being designed to be crossed by the fuel in its path inside the filter between an intake connector (3,24) and a discharge connector (4,26), said enclosure (2) comprising a water collection chamber (7,28) at the bottom, characterized in that it comprises a micromesh (8,11,15,17,19,22,29) which is adapted to be crossed by the fuel that exits from the filtering mass (5,25).
2. The filter according to claim 1, characterized in that the micromesh is located proximate to the surface (5a) on which the fuel exits from the filtering mass (5).
3. The filter according to claim 1, characterized in that the micromesh (11) is located so as to adhere to the surface (5a) on which the fuel exits from the filtering mass (5).
4. The filter according to one or more of the preceding claims, comprising a fuel intake connector (3) which is located proximate to the enclosure (2), with discharge through a connector (4) located in the central region, characterized in that the micromesh (8) located inside the filtering mass (5) is at least partially provided with a bottom (8a).
5. The filter according to claim 4, characterized in that the bottom (8a) of the micromesh (8) is made of micromesh.
6. The filter according to claim 4, characterized in that the bottom (8a) of the micromesh (8) is provided with a blind surface.
7. The filter according to one or more of the preceding claims, comprising a fuel intake connector (3) which is located proximate to the enclosure (2), with discharge through a connector (4) located in the central region, characterized in that the micromesh (11) located inside the filtering mass is bottomless.
8. The filter according to one or more of the preceding claims, comprising a reinforcement sleeve (13) which is adjacent to the internal surface of the filtering mass (5), characterized in that the micromesh (15) is located proximate to said sleeve (13).
9. The filter according to one or more of the preceding claims, comprising a reinforcement sleeve (13) which is adjacent to the internal surface of the filtering mass (5), characterized in that the micromesh (17) is arranged so as to adhere to said sleeve (13) on the inner part of said sleeve (13).
10. The filter according to one or more of the preceding claims, comprising a reinforcement sleeve (13) which is adjacent to the internal surface of the filtering mass (5), characterized in that the micromesh (19) is interposed between the sleeve (13) and the filtering mass (5).
11. The filter according to one or more of the preceding claims, characterized in that it comprises a blind screen (21) which is adapted to be encountered by the fuel that exits from the micromesh (22).
12. The filter according to one or more of the preceding claims, characterized in that the micromesh (29) located proximate to the surface on which the fuel exits from the filtering mass (25) has, at its lower end, a perforated bottom (29a) for connection to said filtering mass.
