Title: OIL FILTER ELEMENT EFFECTIVELY UTILIZING WELL-BALANCED LINES OF MAGNETIC FORCE FROM MUTUALLY REPELLING PERMANENT MAGNETS
Abstract:
Provided is an oil filter element as an alternative to a filter paper element of a filter paper type oil filter for the purpose of reducing exhaust gases (CO, HC, NOX) and reducing emitted particulate matter (PM 2.5) using the oil deterioration prevention effect of well-balanced lines of magnetic force from permanent magnets, and of prolonging the bearing service life through the attraction of minute iron powder in accordance with ISO281. [Configuration] An oil filter element which uses permanent magnets and not a paper filter, wherein in place of the paper filter of the oil filter element, an odd number of permanent magnets 3 to which yokes 2 are applied to both magnetic pole surfaces of each permanent magnet 3, and which have a numeric value expressing a hollow disk-like shape by {(outer diameter–inner diameter)/2 ÷ height} in a usage range of (0.6-4), are arranged on the same center line by providing a pair or multiple pairs of gaps comprising a gap between adjacent N-poles and a gap between adjacent S-poles of adjacent permanent magnets 3, and setting the gaps in a nipple holder 5; the permanent magnets 3 having yokes 2 attached respectively at both ends are placed on a nonmagnetic body such that the same poles of adjacent permanent magnets 3 face each other, and when the permanent magnets 3 are floated in the vertical direction, the gap therebetween is within 1/2 of a distance supporting the local weight of the magnet thereof; a holding plate 4 of a nonmagnetic body in which holes are formed to allow the passage of oil is installed in each of the gap portions of the permanent magnets 3 to stabilize the pair of gaps of the odd number of permanent magnets 3; and a cap magnet holder 1 is arranged at both ends of the nipple magnet holder 5 to stabilize the odd number of permanent magnets 3.
