In addition, the engagement concave portion has a thickness (length in the X direction in FIGS. 1 and 2) and a width (in the Z direction in FIGS. 1 and 2) so that the pump portion 43c can be engaged. It has the same thickness and width as the (length). Thus, when the vibrator unit 4 is inserted into the electromagnet housing 3, the diaphragm housing portion 43b and the pump portion 43c are engaged with the engaging recess while being guided, and the vibrator unit 4 is attached to the electromagnet housing 3. It is done. In addition, you may comprise the pump part accommodating part 32 as an engagement recessed part which engages only the pump part 43c.

  Further, as shown in FIG. 4, the vibrator accommodating portion 43 a is disposed at a position facing the pair of electromagnets 2 when inserted between the pair of electromagnets 2.

The fluid that has moved through the upper passage C5 flows into the suction chamber C1 through the outside of the diaphragm 42, and then passes through the compression chamber C2, the discharge chamber C3, and the discharge port 43e from the discharge port connecting portion 35 to the electromagnet housing 3. It moves to the internal supply path C4. And it discharges to the discharge port 36 from the supply path C4. And since the internal space of the electromagnet housing 3 also functions as a tank that allows fluid to pass therethrough, there is no need to provide a tank through which the fluid to be discharged passes, separately from the housing that houses the electromagnet, as in a conventional electromagnetic pump. A compact pump 1 can also be provided.
