Fuel e.g. petrol, treating i.e. filtering, device for e.g. oil engine of heavy truck, has magnets positioned to create separation constraints between magnets and maintained in position by constraint unit that is made of conductive material

摘要

The device (1) has a gutter shaped element e.g. rail, and parallelepiped shaped axial magnetization magnets (5) arranged at periphery of a cylindrical shaped fuel supply pipe and made of neodymium or a mixture of neodymium, iron and boron. The magnets are arranged opposite to one another and one behind the other along the pipe. The magnets are positioned in a manner to create magnetic separation constraints between the magnets, and are maintained in a position by a constraint unit that is made of non-magnetic field conductive material and provided with a plate (6A).
