DISPOSITIVO ATTUATORE A CAVO FLESSIBILE INCORPORANTE UN ELEMENTO A MEMORIA DI FORMA.

摘要

An actuator device comprises a flexible cable (2) and opposite ends (4, 5), one of which is connected to a control member and the other to a controlled member. At least one portion of the flexible cable (2) is made of a shape-memory material in such a way that the device can be used both as a mechanical element of flexible transmission between the control member and the controlled member, and as a shape-memory actuator, designed to operate the controlled member following upon a variation in length of said shape-memory portion.
