摘要： The known magnet filter in which a permanent magnet piece is wrapped up by a magnetically permeable plate except for at least one magnetic pole surface, is improved. The improvement exists in that the magnetically permeable plate wrapping up a permanent magnet piece is formed in a bag shape with one end opened to the outside, and the permanent magnet is fitted in a deep portion within the bag-shaped magnetically permeable plate so that a space portion may be preserved between an unwrapped surface of the permanent magnet piece and the open end of the magnetically permeable plate for firmly holding adsorbed magnetic metal powder.
摘要翻译：其中永磁体片被除了至少一个磁极表面之外的导磁板包裹的已知的磁体过滤器被改善。这样的改进在于，将永久磁铁片卷绕的导磁板形成为一边向外侧敞开的袋状，将永久磁铁嵌入袋状导磁板的深部，空间部分可以保持在永磁体片的展开表面和导磁板的开口端之间，用于牢固地保持吸附的磁性金属粉末。

摘要： A magnetic filter consisting of a screw plug having a recess formed at the tip end of its screw rod portion and directed in the axial direction thereof, a rod-shaped permanent magnet piece fitted in the recess, and a non-magnetic member interposed between the permanent magnet piece and an inner circumferential surface of the screw rod portion defining the recess. The rod-shaped permanent magnet piece is magnetized so that magnetic poles may appear on its circumferential surface at diametrically opposite ends of its transverse cross-section, and the rod-shaped permanent magnet piece is axially projected from the tip end surface of the screw rod portion.
摘要翻译：一种磁性过滤器，其由具有在其螺杆部的前端形成并沿轴向方向形成的凹部的螺塞，安装在凹部中的杆状永久磁铁片，以及非磁性构件，永磁体片和限定凹部的螺杆部的内周面。杆状永磁体被磁化，使得磁极可能出现在其横截面的径向相对端的圆周表面上，并且杆状永磁体片从螺杆的顶端表面轴向突出一部分。
