Abstract

PURPOSE: To stabilize operation of a solenoid pump by setting the length between the magnetic poles of a solenoid coil larger than that of a piston.
CONSTITUTION: The length (t) between the magnetic poles of a solenoid coil 3 is set larger than the length (III) of a piston 2. When one end of the piston 2 is arranged at one magnetic pole end (t1) at the second position of the piston 2, the other end of the piston 2 passes through the other magnetic pole end (t2) and is positioned inside the magnetic pole. Therefore, the characteristic of attracting force forms a curve (a2), and the set-up increases markedly at the cross oin with the spring force line (b2) of a spring. When this oin is set as the top dead center of the piston, setting of stroke is made certain, and the variation of stroke is little as shown by S1 → S1' even if the atrraction force changes as shown by the curved a2', due to the variation of power voltage, and the solenoid pump can be operated stably.
