Abstract

PURPOSE:To stably maintain the operating characteristics of an electromagnetically controlling device by allowing the coil of an electromagnet for controlling the separation of an attracting plate to be excited in a direction for strengthening the magnetization of the permanent magnet, thereby eliminating the decrease in the magnetization of the permanent magnet. CONSTITUTION:When a pulse current flows through a coil 5, an electromagnet 4 will generate a magnetic flux phi1 in a direction for strengthening the magnetization of a permanent magnet 2. The most of the magnetic flux phi1 of the electromagnet 4 passes through the magnetic path of a yoke 2a, an attracting plate 3 and yoke 2b. Since the magnetic flux phi1 becomes reverse to the direction of the magnetic flux phi2 of the permanent magnet 1, which attracts the attracting plate 3, the plate 3 is separated from the permanent magnet 1, thereby operating a solenoid valve connected to the plate.
