PURPOSE:To eliminate the affection of accuracy of parts measurements and the characteristical variation for the subject proportional electromagnet by a method wherein the pole interval between the armature unit, to be operated according to the relations between a return spring and an electromagnetic attraction, and a core are enabled to adjust by shiftng an attracting piece. CONSTITUTION:The valve 9, which was arranged opposing to the valve seat 10 of a fluid outflowing port 18, is attached inclinably at the point near the core 1 of the armature 4 through the intermediary of a valve mounting device 7, and the valve 9 is retained at the position having an arbitrary opening by the return spring 12, which was hooked to other end of the armature 4, and the attracting force of the core 1 whereon an exciting coil 2 was wound around. On the armature 4, the atrracting piece 5 is installed on the opposed surface of the core 1 in such a manner that the length of the armature unit, consisted of the armature 4 and the attracting piece 5, is adjustable. |
