Abstract:
The invention relates to a vibrator device for a vibratory compacting machine, said device comprising: a tubular body extending longitudinally and having a bottom end; at least one first hydraulic motor disposed in the tubular body and comprising a rotor and a stator; an eccentric member arranged inside the tubular body between the bottom end and the first hydraulic motor, said eccentric member being adapted to be rotated by the rotor of the first hydraulic motor so as to generate vibration. The invention is characterized in that the stator of the first hydraulic motor is constituted by the tubular body.
