Abstract
A zero latching force energy storage device has a first rod (10) sliding along an axis X and subjected to axial thrust from a first spring (17), with the first rod (10) being fixed at a first end to latching means and being coupled at a second end to energy storage means. The latching means include a rod (18) provided with a transverse bore (19) which, when in the set position, receives a latching member (100) controlled by an electromagnet (121). The energy storage means include a second rod (20) slidable along the same axis X and subjected to axial force from a second spring (34), with the free end of the second rod facing the free end of the first rod and being coupling to the first rod (10) and for locking it when the latching member (100) is in its set position.
