Abstract

PURPOSE:To enable stable control of the displacement of a mobile core according to the current of the electromagnetic coil by making the axial length of the surface of the mobile core facing a yoke shorter than that of the surface of the yoke facing the mobile core. CONSTITUTION:A fixed core 13 provided with a electromagnetic coil 12 is arranged inside the housing 11. A mobile core 15 is fixed on a shaft 18 supported coaxially movable in such a manner as to be coaxial with the fixed core 13 while the concave part 13A of the fixed core 13 faces the convex part 15A of the mobile core 15. A yoke 14 is provided on the end of the electromagnetic coil 12 facing the larger diameter part of the mobile core 15. The axial length of the circumference 15d of the large diameter part is made shorter than the length of the inner surface 14a of the yoke. Said mechanism can maintain the attraction force of the fixed core 13 and the mobile core 15 almost constant regradless of the stroke S of the mobile core 15, thereby assuring the stable control of the displacement of the mobile core.
