Abstract

PURPOSE:To enlarge the stroke of a movable iron core by arranging a ring-shaped movable iron core between the attracting surface of an electromagnet and the movable iron core thereof. CONSTITUTION:Between the attracting surface 16 of the electromagnet 10 and the outer flange 19 of the movable iron core 17, two ring-shaped movable iron cores 25 and 26 are arranged in such a manner that they are supported by a guide 24 and move in the axial direction along the guide 24, and the outer periphery of the large- diameter flange of the electromagnet 10 and the outer periphery of the movable iron core 25, the outer periphery of the movable iron core 25 and the outer periphery of the movable iron core 26, and further the outer periphery of the movable iron core 26 and the outer periphery of the outer flange 19 of the movable iron core 17 are connected with each other by means of cords 27, 28 and 29, respectively. By these cords, the maximum distances between respective members are regulated. By this constitution, leakage of a magnetic flux formed between the attracting surface 16 and the movable iron core 17 is prevented and thus the stroke of the movable iron core 17 can be enlarged.
