An oil filter element that effectively uses a well-balanced magnetic force line in which permanent magnets repel each other

摘要

(CO, HC, NOx) due to the effect of prevention of deterioration of the oil of magnetic force lines of a permanent magnet having good balance, reduction of particulate emissions (PM2.5) and bearing life due to adsorption of fine iron by ISO281 The filter element of claim 1, wherein the filter element is a filter element. Instead of the filter paper of the oil filter element, the numerical value of {(outer diameter-inner diameter) / 2 / height} of the hollow disc shape is set to (0.6 to 4) A plurality of permanent magnets 3 of an odd number provided with a yoke 2 on a surface thereof and permanent magnets 3 adjacent to each other have a gap formed by N poles and N poles and a gap formed by S poles and S poles, A plurality of pairs of gaps are provided and set on the nipple magnet holder 5 so that they are arranged on the same center line and the permanent magnets 3 whose gaps are attached to both ends of the yoke 2 are placed on the non- A holding plate (4) of a nonmagnetic material in which a hole for allowing oil to pass is formed in the gap portion of the permanent magnet (3) is provided within a distance of 1/2 of a distance to support the weight of the permanent magnet And stabilizes the gap of a pair of the odd number of permanent magnets 3, Both ends of the magnet holder (5) has an oil filter element by the permanent magnet that in use the filter paper is thereby disposed to the cap magnet holder (1), stabilizing the odd number of permanent magnets (3).
