<p>A vibratory assembly (1, 2) is supported on a housing (5) by spring blades (3, 4). A rotary motor (6) with a reciprocating motion drives an actuating member (9) to which are secured (at 10) the first ends of two wire-shaped members (11, 12) whose second ends are secured in a part (13) rigidly secured to the vibratory assembly. The reciprocating motion of the actuating member is thus transmitted in both directions by the flexible traction members (11, 12).</p> |
