FIELD: machine building.
SUBSTANCE: filter is designed for filtration of medium passing through it. Filter includes housing 1 having inlet 2 and outlet 3 coupling pipes located on one axis on both sides and provided with sections of internal thread 4 and filtration chamber 5 located in radial direction relative to axis of coupling pipes 2, 3, cover plate 6 of filtration chamber 5, as well as filtering element 7 in the form of bushing. Clear gap of housing 1 between coupling pipes 2, 3 is covered with dividing cross connection 8 passing to filtration chamber 5. Filtration chamber 5 has annular centring element 9 adjacent to end part 10 of filtering element 7, which passes along dividing cross connection 8 and some part of housing 1 in zone 11 of inlet coupling pipe 2. In the centre of annular centring element 9 there located is hole 12 to cavity of inlet coupling pipe 2. Cover plate 6 of filtration chamber 5 is made in the form of a cap with section of internal thread 13 along the edge, by means of which it is fixed in section of external thread of filtration chamber 5, and annular centring element 15 at its bottom, which is adjacent to end part 16 of filtering element 7. Inner side walls 17 of filtration chamber 5 and inner side walls 18 of cover plate 6 of filtration chamber 5 are located at some distance from external surface 19 of filtering element 7 for formation of annular cavity 20 located around filtering element 7 and interconnected with cavity of outlet coupling pipe 3 along dividing cross connection 8. Annular centring elements 9 and 15, as well as filtering element 7, are located on one axis intersecting with location axis of inlet 2 and outlet 3 coupling pipes at sharp angle to it with some part of axis on the side of inlet coupling pipe 2. Side surfaces 21 and 22 are provided with linear generatrixes parallel to axis of filtering element 7, which has filtering ability within 15-10000 mc.
EFFECT: enlarging the number of filtration means of transported medium flowing via pipeline, which allow using filtering elements with various filtering ability in wide range of values, and namely due to intensification of medium passage through filtering element.
