<p>An oil filter does not use filter paper but uses permanent magnets. In place of elements composed of filter paper in an oil filter, which uses filter paper, magnet type elements are used such that gaps between permanent magnets, of which an N pole and an N pole or a S pole and a S pole repulse each other, are made smaller to render lines of magnetic force more intense, and oil flows through the gaps to thereby generate turbulent flows and attract magnetic powder, an influence given by lines of magnetic force prevents deterioration of the oil, and a magnetic field space is obtained in a portion of a space occupied by filter paper in a conventional oil filter, which uses filter paper. Thus it is possible to further securely attract magnetic powder, and extend a period of time, during which the oil passes through a zone of lines of magnetic force. <IMAGE></p> |
