Abstract
PURPOSE: To produce great torque with a low-capacity solenoid coil, by converting the attractive and repulsive force of a permanent magnet into reciprocating slide action.
CONSTITUTION: The tip of a cylinder 17 in an external case 14 is repeatedly magnetized from N to S and vice versa, as a solenoid coil 22 is applied with an alternative current. This change in polarity makes a permanent magnet 19 attached to a piston 18 attracted or repulsed in the cylinder 17. This reciprocating movement actuates a check valve 20 of the piston 18 to take in and discharge liquid or gas from a suction port to a discharge port. The reciprocating movement of the piston 18 utilizing the attraction and repulsion of the permanent magnet 19 can increase the driving force of the piston and also produce great torque for the pump, even when the capacity of the solenoid coil 22 is relatively small.
