摘要:
A pump includes a diaphragm vibrated by a piezoelectric element and a case. An inlet orifice and an outlet orifice are disposed on an outer surface of the case. An inlet path connects the inlet orifice to an inlet and an outlet path connects the outlet orifice to an outlet. At least one portion of the inlet orifice and at least one portion of the outlet orifice are positioned higher than the diaphragm in the case, and portions of the inlet path and the outlet path connecting to the inlet orifice and the outlet orifice are positioned higher than the diaphragm.
