Specifically, the horizontal member 710 is received by the holes, such as holes 302 and 402, of the driving disc 300 and the first disc 400. Therefore, the horizontal member 710, particularly the cylindrical member 718 of the horizontal member 710 moves forward, whereas the flat member 716 of the horizontal member 710 pivots about the bolt 720. The forward movement of the cylindrical member 718 of the horizontal member 710 causes the spring 902 to get compressed between the driving disc 300 and the flange 722.
  • the forward movement of the cylindrical member 718 causes the magnet block 802 to move forward and away from the driving disc 300. Due to the forward movement of the cylindrical member 718, the magnet block 802 moves towards repelling magnet 1200. It is to be understood that the repelling magnet 1200 may be adjusted in a manner such that the magnet block 802 moves towards the repelling magnet 1200 with the forward movement of the magnet block 802. As explained herein above, the poles of the plurality of magnet blocks, such as the magnet block 802, faces similar pole of the repelling magnet 1200.

  • the SMA wire 1002 when the SMA wire 1002 is released from the contact of the fluid 1120, the SMA wire 1002 tends to extend. More specifically, such extension of the SMA wire 1002 occurs due a temperature difference between the ambient temperature and the temperature of the fluid 1120, in which the SMA wire 1002 is dipped. Typically, for the extension of the SMA wire 1002 the temperature difference should be at least 20 Degrees Celsius. For example, if the fluid 1120 is at 70 degrees Celsius (operating temperature), the ambient temperature should not exceed 50 degrees Celsius for allowing the extension of the SMA wire 1002. Further, in this instance, the extension of the SMA wire 1002 may also occur in the temperature range, when the ambient temperature is in- between minus 10 degrees Celsius to 50 degrees Celsius and the fluid 1120 is at 70 degrees Celsius.
  • the spring 902 gets compressed due to the contraction of the SMA wire 1002. Therefore, when the SMA wire 1002 is released from ⁇ he fluid 1120, the compressed spring 902 tends to push back the cylindrical member 718 of the horizontal member 710, thereby pivotally moving the vertical member 712 in a forward direction (opposite to the direction shown with the arrow 'A'). The pivotal forward movement of the vertical member 712 due to the expansion of the spring 902 further enables the extension of the SMA wire 1002.
  • the SMA wire 1002 when the SMA wire 1002 is released from the contact of the fluid 1120, the next SMA wire, such as the SMA wire 1004, comes in contact with the fluid 1120 due to the simultaneous rotation of the second disc 500 and the third disc 600. Therefore, the corresponding lever, such as the lever 704, connected with the SMA wire 1004 is maneuvered in similar manner as explained above in conjunction with the lever 702. This causes corresponding magnet block, such as the magnet block 804 connected with the lever 704, to move towards the repelling magnet 1200.

Abstract

L'invention porte sur un dispositif de génération d'un mouvement rotatif d'un arbre. Le dispositif comprend une armature de support, un arbre, une pluralité de disques, une pluralité de leviers, une pluralité de fils en alliage à mémoire de forme, une pluralité de blocs magnétiques, un aimant répulsif, un contenant apte à stocker un fluide, et un mécanisme de chauffage apte à chauffer le fluide. Le chauffage du fluide permet à au moins un fil en alliage à mémoire de forme en contact avec le fluide de se contracter. La contraction du fil en alliage à mémoire de forme manœuvre un levier correspondant relié au fil en alliage à mémoire de forme. Le levier correspondant manœuvré déplace un bloc magnétique correspondant vers l'aimant répulsif. L'aimant répulsif repousse le bloc magnétique afin de permettre à un disque d'entraînement de la pluralité de disques d'accomplir un mouvement rotatif. Le contact ultérieur de la pluralité de fils en alliage à mémoire de forme avec le fluide amène le disque d'entraînement à tourner de manière continue, de façon à générer ainsi un mouvement rotatif continu de l'arbre.
