Device for the magnetic treatment of water and liquid and gaseous fuels

A device for the magnetic treatment of fluids such as water and liquid and gaseous fuels comprising:

• an elongated, tubular intermediate casing of magnetic material,
• an elongated magnet having opposite ends and at least two axially spaced poles,
• an inner casing of non-magnetic material encasing said magnet, said inner casing having a cylindrical outer surface and including open tubular end portions extending beyond opposite ends of said magnet and having inner and outer surfaces extending longitudinally with respect thereto,
• said inner casing and magnet being positioned longitudinally within said intermediate casing, the end portions of said inner casing being smaller in diameter than the inner diameter of said intermediate casing and being slidable out of said intermediate casing when the device is disassembled,
• a pair of end fittings threadedly connected to opposite ends of said intermediate casing, said fittings including externally open fluid passages therein,
• each of said end fittings including a recess having an inner surface spaced from and opening toward said magnet, said recesses having the respective opposite tubular end portions of said inner casing slidably seated therein so as to space said inner casing from said intermediate casing to form a generally annular treatment chamber therebetween, the inner surface of each of said recesses including tapered surface means such that the recess decreases in diameter in a direction away from the magnet and has a maximum inner diameter greater than the outer diameter of the end of the inner casing seated therein and a minimum inner diameter smaller than the outer diameter of the end of the inner casing seated therein, and the respective tubular end portion is seated directly against the inner surface of the recess and supported against radial movement by the inner surface of the recess,
• said tapered surface means providing a greater radial inward tapering force than an axial compression force for gradually tapering inwardly the end portions and snugly supporting them in the recesses as the end fittings are threaded on said intermediate casing,
• said recesses being in fluid communication with the fluid passages of the respective end fittings, and
• apertures in each of said tubular end portions providing fluid flow paths from within the tubular end portions to said treatment chamber.
