摘要:
An actuator comprises an elongated shape-memory element wound around a first element and having one first end connected to the first element and one second end connected to a second element. Heating means are provided for heating the shape-memory element in order to obtain a displacement of one of the ends thereof. The elongated shape-memory element is guided so that it can slide within a closed channel made of a material having a low coefficient of friction, for example defined by a sheath.

A sunshade device comprises a sunshade in the form of a roller blind forming part of a roller-blind device, comprising a supporting structure, a shaft for rolling of the sunshade blind, mounted so that it can rotate on the aforesaid supporting structure, and a shape-memory actuator device for causing displacement of the blind from the rolled-up condition to the distended condition.

摘要:
A lock device which includes a bolt actuated by a flexible shape memory element. The memory element can assume an extended or a shortened configuration as a result of heating. A constraining element which includes two points between which an intermediate portion of the shape memory extends is also provided. The two points belong to a moveable transmission element which moves when the shape memory element extends. As a result, a controlled element is moved from between an operating position and a non-operating position.

A device for controlling the flow of a fluid in one or more conduits in an electrical appliance, particularly in a dishwasher machine, comprises at least a control member, movable between two or more positions, and shape memory actuator means of said control member.
摘要:
A locking device for preventing the rotation and/or the axial movement of a pin includes a coil spring wound around at least a portion of the pin and having one end rigidly connected to a support structure. In its undeformed condition, the spring has an internal diameter smaller than the diameter of the pin, whereby in its resting condition the spring is tightened around the pin to prevent a rotation thereof at least in a direction or an axial movement in any direction. The device includes shape memory means for causing the unwinding of the turns of the spring for the purpose of temporarily releasing the pin.

A lock (1) comprises at least a bolt (7) actuated by means of a flexible shape memory element (14), which can take an extended and a shortened configuration as a result of heating. Constraint means (P, 10, 17) cause the arrangement of at least an intermediate portion of the shape memory element (13), within which portion said element is associated to the bolt (7); the constraint means (P, 10, 17) are in such relative positions that said intermediate portion of the shape memory element (14) takes a substantially V-shaped arrangement at least when the first controlled element (7) is in its operating position.
