    • A piezoelectric pump includes a casing formed of a plurality of metallic members welded and thus joined together, a piezoelectric element dividing an internal space of the casing into a working space and a back pressure space, and internal components formed of resin, and provided between the casing and the piezoelectric element and holding the piezoelectric element. The internal components are formed of workable and moldable resin. The internal component defines a perimeter of the working space and the internal component defines a perimeter of the back pressure space. The internal components are arranged opposite each other to form a recess therebetween to receive and thus hold the piezoelectric element therein.
    • 一种压电泵包括由多个金属构件形成的壳体,焊接并接合在一起,将壳体的内部空间分成工作空间和背压空间的压电元件以及由树脂形成的内部构件, 壳体和压电元件并保持压电元件。 内部组件由可加工和可模制的树脂形成。 内部组件限定了工作空间的周长,内部组件限定了背压空间的周长。 内部部件彼此相对布置以在其间形成凹部,以将压电元件容纳并保持在其中。
