    • A shape memory bistable actuator includes an element movable mounted on a fixed support structure, having an intermediate position of dead center and two end positions. Spring means tend to return the movable element towards either end positions, depending on that it is on either part with respect to the dead center position. Shape memory means are provided for causing a displacement of the movable element from either end positions, against the action of the spring means, at least until the dead center position is exceeded. After this exceeding, the activation of the shape memory means can be stopped, as the spring means provide to proceed the movable element toward the new desired working position, and to hold it in such a position, despite the shape memory means are deactivated.
    • 形状记忆双稳态致动器包括可移动地安装在固定的支撑结构上的元件,具有死点的中间位置和两个端部位置。 弹簧装置倾向于将可移动元件朝向任一端部位置返回,这取决于它相对于死点位置在任一部分上。 提供形状记忆装置,用于使可动元件从任一端部位置抵抗弹簧装置的作用移动,至少直到超过死点位置。 在此之后,尽管形状记忆装置被停用,但可以停止形状记忆装置的激活,因为弹簧装置提供使可移动元件朝新的期望的工作位置移动,并将其保持在这样的位置。
