    • A proportional magnet for a hydraulic directional control valve and a method for the production thereof. The proportional magnet has a coil unit, a bearing unit and a pole disk. The coil unit has a cylindrical coil, a cylindrical magnet casing surrounding the coil, an annular yoke disc arranged at a face of the magnet casing and a housing. The bearing unit has a yoke with a first bearing point, a pole core with a second bearing point, and an armature unit with a magnet armature and a pressure pin. The bearing points and armature unit are aligned coaxially by a centering sleeve. When mounting the proportional magnet, the bearing unit is inserted into a cylindrical opening of the coil unit and the pole disc is put on the coil unit after the bearing unit is inserted for axially fixating the bearing unit and closing the magnetic circuit.
    • 一种用于液压方向控制阀的比例磁铁及其制造方法。 比例磁体具有线圈单元,轴承单元和极盘。 线圈单元具有圆筒形线圈,围绕线圈的圆柱形磁体壳体,设置在磁体壳体的表面处的环形轭盘和壳体。 轴承单元具有带有第一轴承点的轭,具有第二支承点的磁芯,以及具有磁体电枢和压力销的电枢单元。 轴承点和电枢单元由定心套筒同轴对准。 当安装比例磁铁时,将轴承单元插入线圈单元的圆柱形开口中,并且在插入轴承单元以轴向固定轴承单元并闭合磁路之后,将磁极盘放在线圈单元上。
