<p>magnetic filter including a tubular case (1) which has a filter region (10) divided along a flow passage (7) into two smaller-dimensioned spaces (11, 12) in each of which a filter element of magnetic material is located. A magnetic means (26) is also provided in one of the two spaces. In the smaller-dimensioned space (11) including the magnetic means (26), only a portion of the lines of magnetic force produced by an electromagnetic coil (22) connected to the tubular case is allowed to magnetize the filter element disposed in the same space (111, while the remaining lines pass through the magnetic means (26), so that the filter element is magnetized to a minor degree However. the filter element located in the other smaller-dimensioned space (12) is magnetized by all the lines of magnetic force, so that the same space has a higher capacity for attracting magnetic particles Therefore different types of magnetic particles contained in d flud are attracted by the lewly magnetized filter element and the highly-magnetized one, respectively</p> |
