Abstract
An electromagnetic pump includes a coil bobbin with an excitation coil, a pair of magnetic cylinders, a printed circuit board with a transistor, and a pump housing. The coil bobbin is disposed around a sleeve member having a plunger therein. The pair of magnetic cylinders are axially inserted from two ends of the bobbin between the inner surface of the coil bobbin and the outer surface of the sleeve member. The pump housing consists of a cup-like housing body and a lid. The plunger, the magnetic cylinders and the pump housing are made of a magnetic material to form a magnetic flux path from the excitation coil.
