PURPOSE:To strengthen the vibration force of a rod and increase the discharge faculty of a pump by forming the top edge of at least one among the main and side electrodes of an electromagnet into a specific form and increasing the gap between the main and side electrodes and increasing the number of winding of a coil. CONSTITUTION:An electromagnetic coil A is constituted of a core 1, coil frame 5, and a coil 6. A rod 8 having two permanent magnets 7a and 7b is installed in the intermediate part of a pair of electromagnetic coils A. The gap between the main and side electrodes is increased, and the top edge of at least one of the main and side electrodes is bent towards the top edge of the other electrode or projected or formed into a separated body, and then fixed, and the top edges of the both electrodes are set close to each other. Thus, the vibration force of the rod is strengthened, and the discharge capacity of the pump can be greatly increased. |
