Abstract

PURPOSE: To eliminate the function of an exciting coil to support the valve and minimize the exciting coil, by arranging permanent magnets to develop opposite polarity for the up-and-down movements of the moving iron core of an electromagnetic valve and also arranging an exciting coil around the moving iron core.
CONSTITUTION: A three-way valve is constituted by arranging a changeover switch to a valve body provided with a pressurized air source port 1, output port 2 and exhaust port 3. The changeover switch 5 is connected to the moving iron core by the rod 6, and according to state of the current to the exciting coil arranged around the core 7, the core is moved up and down. Permanent magnets 9 and 8 are respectively placed above and below the moving iron core 7. With no current to the exciting coil, the moving iron core 7 is attached to and supported by either one of the permanent magnets. If, for example, the moving iron core 7 is attached to the permanent magnet 8, current is introduced to the exciting coil in such direction as to develop magnetic poles in the lower face of the moving iron core develop magnetic poles in the lower face of the moving iron core 7 with the polarity that repels the permanent magnet 8, and the moving iron core is moved upwards.
