Disclosed is a drive unit operable to translate and rotate a shaft, the drive unit including: (i) a hollow electric motor (45) having a rotor (47), (ii) a fluid cylinder (48), (iii) means for connecting the shaft to the rotor (47) of the hollow electric motor (45), (iv) means permitting the shaft to move lengthwise coupled with the fluid cylinder (48), and (iv) means connecting the fluid cylinder (48) to the shaft. The shaft may be rotated by the hollow electric motor (45) and moved lengthwise by the fluid cylinder (48). The fluid cylinder (48) has an outer wall coupled with the rotor (47) of the hollow electric motor (45).

L'appareil divulgué est un mécanisme d'entraînement pouvant servir à faire tourner un arbre, ledit mécanisme comprenant : (i) un moteur électrique creux (45) doté d'un rotor (47), (ii) d'un cylindre de liquide (48), (iii) d'un dispositif permettant de raccorder l'arbre au rotor (47) du moteur électrique creux (45), (iv) d'un dispositif permettant à l'arbre de se déplacer dans le sens de la longueur, couplé au cylindre de liquide (48), et (iv) d'un dispositif raccordant le cylindre de liquide (48) à l'arbre. Il est possible de faire tourner ce dernier au moyen du moteur électrique creux (45) et de le déplacer dans le sens de la longueur au moyen du cylindre de liquide (48). Ce dernier (48) comporte une paroi extérieure couplée au rotor (47) du moteur électrique creux (45).
