摘要： The invention relates to an internal vibration device having an electrical motor mounted in a vibrating unit housing and having a rotating device comprising an out of-balance mass that is also mounted in the vibrating unit housing. The invention is characterized in that eccentricity of a center of gravity of the out-of-balance mass can be varied relative to the axis of rotation of said out-of-balance mass depending on the direction of rotation of the electrical motor. Said internal vibration device is suitable both for compacting unset concrete and for distributing concrete in the formwork.
