Se reivindica tornillo hidráulico, caracterizado por que además del husillo principal accionado por la manivela de mando, contiene otro husillo interior que acciona también por la misma manivela de mando que oprime el pistón del multiplicador hidráulico, que a su vez transmite la fuerza ejercida en la misma dirección, pero aumentada diez veces en su intensidad.
