<p>A device ( 10) for generating oscillating motion, comprising a pivot (2) that is adapted to be mated rotatably and eccentrically to a shaft (1) which in turn rotates, the pivot (2) ending at the output with eccentric means (3) that are adapted to allow mating with an element that is retained so as to slide in a single direction, the rotation of the pivot (2) within the rotating shaft (1) producing two different eccentricities of the eccentric means (3) in the two directions of rotation.</p> |
