Magnetic apparatus for treating fluid fuels

The invention discloses a magnetic treatment device for fluid fuels, which exhibits a cylindrical flow chamber with a conical part widening in the direction of flow and a conical, magnetic insert with at least two fiat and/or annular, permanent magnets arranged axially at a distance from each other, whereby the magnetic insert is held against the direction of flow with a force, e.g. intrinsic weight and/or the force from a spring and is mounted in the region of the conical part in such a manner that it can be moved axially. A magnetic treatment device for fluid fuels, which exhibits a cylindrical flow chamber () with a conical part () widening in the direction of flow (A) and a conical, magnetic insert () with at least two flat and/or annular permanent magnets () arranged axially at a distance from each other, whereby the magnetic insert is held against the direction of flow with a force, e.g. intrinsic weight and/or the force from a spring and is mounted in the region of the conical part in such a manner that it can be moved axially, and in which the permanent magnets () are held at a distance from each other by spacing rings () or discs made from non-ferromagnetic material which are placed only in an inner region, between mutually facing surfaces of the permanent magnets, and a bearing shoulder () is allocated to at least one permanent magnet () in the wall of the conical part () of the flow-chamber ().
