The magnet element filter is an element for spin-on filters for removing metallic fines from the medium being filtered and for neutralizing sulphuric acids therein comprises a base element having a lower recess for a magnet and an upper recess larger than the lower recess. Extender elements are stackable on the base element and an upper container within which are placed magnets spaced apart by flux spacer elements is nested in the uppermost extender element. A magnesium coil is on the exterior of the container.It is an object of the magnet element filter to provide an improved spin-on oil filter structure of the type referred to above which provides an assembly of the magnesium helix and magnetic metal combination which is readily adapted for utilization in different sized spin-on filters, is easily disassembled for cleaning and removing of accumulated metallic fines, and wherein the magnetic pull of the core portion is more evenly distributed along its longitudinal length as opposed to being concentrated primarily at its ends as in the prior development. Such structures are intended for use in spin-on type filters for crank case lubricant and such filters which are used in heavy duty transmission and hydraulic systems. The container is provided with inlet and outlet means at the inner end thereof which end is attached to the engine block or transmission in a conventional manner. Oil from the engine or transmission flows from the region of the internal walls of the outer container through a filtering unit which is comprised of multiple wrapped layers, fibrous batt, or accordion pleated sheets as is well known. The oil flows towards the cylindrical central core and from there returns to the engine/transmission through a central outlet. Magnetic bars were enclosed within the helix. In accordance with the present magnet element filter i have found that the magnesium helix coil portion may be shortened, but the outer end with the extended terminus is kept substantially the same length. The coiled portion of the helix is mounted on or about the upper portion of a cylindrical pedestal assembly that is readily adaptable to different lengths.
Within the adjustable pedestal assembly are retained at least two cylindrical or button magnets. The pedestal assembly which supports the helix and carries the magnets within it is comprised of an inert plastic such as nylon, acetal resins such as polyoxymethylene homopolymers and copolymers based on trioxane sole under the trademarks delrin and celcon, and polytetrafluoroethylene sold under the trademark teflon and consists of a base, a central section, and top hollow cylinder, which when assembled together form an adjustable length pedestal containing cylindrical magnets and providing an adjustable height pedestal for the magnesium helix pedestal. This pedestal is comprised of a hollow cylindrical base portion closed at the bottom end. The base provides a cylindrical space for receiving a cylindrically shaped defined space.
