The technical result: an increase in the range of filtration means for transported fluid, ensuring a high degree of cleaning due to use of the cascade principle. The rinsing filter comprises a housing 1 with collared ducts 2, 3 on same axis, and a filtration assembly located transversely to said axis and including a bowl 5 and a filtering element 6 in the form of a sleeve. The clearance of the housing 1 cavity between the inlet 2 and outlet 3 collared ducts is closed by a dividing partition 7. The housing 1 has an annular aligning element 8 facing outwards which extends along the dividing partition 7 and a portion 9 of the housing 1; an inlet hole 10 of the filtering assembly opened to the cavity 11 of the inlet collared duct 2 is located at the centre of the housing 1. The bowl 5 has an annular aligning element 13 located on its bottom 12, and a closeable filtered fluid discharge unit 14, is the bowl 5 being tightly secured over the edge 17 of the housing 1. The filtering element 6 is arranged with its one end 20 in the annular aligning element 8, and with the other end 21 in the annular aligning element 13. The internal side walls 22 and 23 of the bowl 5 and of housing 1 are spaced from the external surface 24 of the filtering element 6 to form an the annular cavity 25 around it in communication with the cavity 26 of the outlet collared duct 3. The filtering element 6 includes an external 27 and internal 28 filtering cylinders made of mesh, installed in each other concentrically with a clearance 29 relatively to the abutting side surfaces and secured by the ends 20 and 21 in top 30 and bottom 31 annular retainers. The bottom retainer 31 has surfaces at its end facing the filtering cylinders 27 and 28 that are arranged at an angle to the top on the side of its other end. The filtering capacity of the outer filtering cylinder 27, in terms of the size of particles removed, is less than the filtering capacity of the inner filtering cylinder 28. |
