摘要

Improvements in electromagnetic pumps for fluid delivery, consisting essentially of providing the driving electromagnet with an axial passage in which a rod supported by its ends by elastic diaphragms, carrier of the moving armature of the electromagnet and of an elastic piston is movable whose edge adjusts with the side walls of a pump chamber, forming on one of its sides an impelling suction chamber provided with intake valves that communicate it with the entrance and capable of separating from said walls, giving way to a discharge enclosure located on the opposite side, in print runs.
