Abstract:
Magnetic treatment device for fluid fuels comprising a body having a cylindrical flow chamber (6) defined in a conical part (17,18) widening in the direction of flow (A) and a generally conical magnetic insert (16) comprising at least two flat or annular permanent magnets (10,11,12,13), the permanent magnets being held axially at a distance from each other by means of spacing rings/discs (14) made from non-ferromagnetic material which are placed at mutually facing surfaces of the magnets, and the magnetic insert is held against the direction of flow with a force and is mounted in the region of the conical part in such a manner that it can be moved axiallycharacterized in that the spacing rings/discs (14) made from non-ferromagnetic material are positioned only in an inner region between mutually facing surfaces of the permanent magnets (10,11,12,13) by being constructed with a short radial width between an inner circular surface and an outer circular surface which is significantly shorter that the radial width of adjacent annular magnets thereby to form a significant annular space between said mutually facing surfaces of the permanent magnets and radially outwardly from said outer circular surface of each ring/disc (14), and said conical part (17, 18) having at least one bearing shoulder (19) for seating at least one permanent magnet (10,12) in the wall of the conical part (17) of the flow chamber (6) such that said annular space and said at least one bearing shoulder (19) create higher flow speeds and/or cause turbulence in the region of the bearing shoulder (19).
