Abrégé

This device comprises an electromagnetic coil (3) in which there is able to slide a piston (6) which has at least a portion made of a material having paramagnetic susceptibility and which is placed in contact with the mechanical member when the drive device (1) is in the rest state. Electrical energy supply means are provided in order to store electrical energy and to abruptly release this energy into the coil and thus apply the high-energy magnetic movement pulse to the mechanical member. According to the invention, the piston (1) comprises a stack (9) of blocks (11, 12) which are made alternately from the material having paramagnetic susceptibility and an insulating material; and the electrical energy supply means are provided in order to allow the energy to be applied to the coil in the form of a series of electrical pulses which appear as the piston (6) moves.

Abrégé

The device of the invention comprises an electromagnetic coil (3) in which a piston (6) is capable of sliding and has at least one portion made of a material having a paramagnetic susceptibility and in contact with said mechanical member when said driving device (1) is at rest. An electric supply means is provided for storing electric energy and for abruptly releasing said electric energy into the coil, thus applying a movement pulse with high magnetic energy to said mechanical member. According to the invention, the piston (1) comprises a stack (9) of blocks (11, 12) alternatively made of the material having a paramagnetic susceptibility and of an insulating material. The electric supply means is provided so as to apply the energy to the coil in the form of a succession of electric pulses occurring together with the movement of said piston (6).
