Abstract
A vibrator for vibrating an object. The vibrator is provided with a rotary housing mounted on a frame for rotation about an axis. Multiple rotary eccentric masses are mounted at equally spaced intervals in this housing about the housing axis and they are mounted for rotation on their respective axes which are parallel to the housing axis. A rotary drive is connected for simultaneously rotating the eccentric masses in the same direction and in synchronism such that all masses are directed simultaneously to their inner most and their outer most positions of movement relative to the housing axis. This generates a force moment about the housing axis which rotatably oscillates the housing.
