    • Piezoelectric pump for a household electric appliance having a moving wall interposed between a first casing element defining a pumping chamber with the moving wall, and a second casing element applying pressure to the periphery of the moving wall in order to hold the latter in position. The moving wall has an exterior face in contact with a piezoelectric actuator designed to cause the moving wall to move so as to bring about a periodic variation in the volume of the pumping chamber under the action of the piezoelectric actuator wherein the first casing element and the second casing element are held together under stress by an elastic clip, the elastic clip applying a pressure that tends to compress the first casing element onto the second casing element.
    • 一种用于家用电器的压电泵,其具有插入在限定泵送室与移动壁之间的第一壳体元件之间的移动壁,以及向移动壁的周边施加压力以将其保持在适当位置的第二壳体元件。 活动壁具有与压电致动器接触的外表面,该压电致动器被设计成使得移动壁移动,从而在压电致动器的作用下引起泵送室的体积的周期性变化,其中第一壳体元件和 第二壳体元件通过弹性夹子在应力下保持在一起,弹性夹施加倾向于将第一壳体元件压缩到第二壳体元件上的压力。
