Claims

[Scope of utility model registration request]

a reciprocating shaft driven by the magnetic action of an electromagnet; a diaphragm bent by the reciprocating motion of the reciprocating shaft; an electromagnet casing that surrounds at least a portion of the electromagnet; and an outer peripheral edge of the diaphragm that is connected to the electromagnet. An electromagnetic reciprocating type comprising a fluid working chamber casing that is clamped to a casing and forms a fluid working chamber with the diaphragm, and a fluid suction valve and a fluid discharge valve provided in the fluid working chamber casing. In the fluid pump, a fluid inflow path or a fluid outflow path is formed in the electromagnet casing and the fluid working chamber casing, the fluid inflow path or the fluid outflow path communicating with each other and with the fluid intake valve or the fluid discharge valve, respectively, and the fluid inflow path Alternatively, the fluid outflow path is isolated from the outside air by interposing a seal packing part integrally formed on the outer peripheral edge of the diaphragm between the electromagnet casing and the fluid working chamber casing. Reciprocating fluid pump.
