。 An electromagnet fixed to a housing, a magnetic armature that moves in a direction across the magnetic flux on the center line between opposing magnetic poles of the electromagnet, and a valve device that is slidably installed in a cylinder and reciprocates together with the magnetic armature. The valve device in the electromagnetic pump includes a piston and a coil spring that integrally moves a combination of a magnetic armature and the piston back together for an elastic force when the electromagnet is demagnetized, the valve device being connected to the cylinder wall surface. An electromagnetic device comprising: a flexible discharge valve that closes the opening end of a discharge hole formed by penetrating the discharge hole; and a valve retainer made of a two-way shape memory element that holds the valve from the outside. Valve device for type pump.
