Claims

[Scope of utility model registration request]

(1) A pipe is arranged at the axial center of the electromagnetic coil, an electromagnetic plunger is provided inside the pipe that moves reciprocally by the electromagnetic force of the electromagnetic coil, and a pumping action is performed by the reciprocating movement of a cylinder or pressure plunger connected to the electromagnetic plunger. In an electromagnetic plunger pump, a cut-off valve seat and a cut-off valve chamber are formed in a discharge joint provided on a pump body, and a cut-off valve is disposed in the cut-off valve chamber facing the cut-off valve seat, and An off spring is interposed between the cutoff valve and the discharge joint to bias the cutoff valve toward the cutoff valve seat, and the lower collar of the cutoff valve is inserted into the discharge valve cover connected to the electromagnetic plunger. The cut-off valve is arranged so that it can slide freely within a certain range above and below the discharge valve cover, and when the electromagnetic coil is not energized, the cut-off valve is seated on the cut-off valve seat, and when the electromagnetic coil is energized, the cut-off valve is seated on the cut-off valve seat. An electromagnetic plunger pump characterized in that a cut-off valve is interlocked with the movement of the cut-off valve, and a cut-off valve seat opens.
