摘要

Mechanism for the functional positioning of mobile elements, especially a mechanism that, being actuable by electrical energy, leads to mobile elements endowed with a single degree of freedom, whether of rotation or translation, to reach stably two limit functional positions, characterized in that it comprises transmission means which, on the one hand connected to the movable elements, are constituted by mechanisms of the group comprising the motion transforming mechanisms and the movement amplifying mechanisms and, in turn, are related on the other hand to motor means that, constituted by an electrically powered thermal expansion actuator, act on said transmission means exerting on them, in their activated situation, an effort along an extension stroke and, in their deactivated condition, an effort throughout a retraction race that is of equal magnitude d that the previous one and of opposite sense.
