The present invention relates to an actuator device configured for impelling elements between two positions such that, in the end position with maximum extension, the force being applied is limited, preventing the impelled element from becoming damaged. 1. An actuator device (A) for actuating linear displacement , comprising:{'b': '1', 'a main rod ();'}{'b': 3', '4', '3, 'a first chamber () housing a substance () such that its specific volume changes in the event of temperature changes, the first chamber () being configured to be in thermal contact with a heat source;'}{'b': 2', '3', '4', '3, 'an inner rod () emerging from the first chamber () and movable in an axial direction (X-X′) to apply a drive force in response to the variation in the volume of the substance () housed in the first chamber ();'}{'b': 5', '2', '1', '10', '10, 'a first base () adapted for being impelled by the inner rod () and movable in the axial direction (X-X′), wherein the main rod () is movable in the axial direction (X-X′) and is attached to a second base () either at an end or close to an end, wherein said second base () is movable in the axial direction (X-X′);'}{'b': 8', '1', '5', '8', '5', '8', '1', '10, 'an inner support surface (.) attached to the first base () by means of a spacer element () separating it according to the axial direction (X-X′) from said first base (), wherein the inner support surface (.) limits the movement of the second base ();'}{'b': 6', '5', '10', '10', '5', '6, 'a first spring () with a first elastic constant located with one end supported on the first base () and the opposite end supported on the second base (), such that the second base () can be moved closer to the first base () by means of compressing the first spring ();'}{'b': 9', '3', '5', '8', '1', '10', '7, 'claim-text': {'b': 7', '5', '9', '5', '7', '5', '2, 'the second spring () is located with an end supported on the first base () and the opposite end supported on the outer shell (), such that the ...
