Abstract

A device for generating directed vibrations has two centrifugal weights which are independently driven at the same speed of rotation but in opposite directions. The centrifugal weights are supported on a largely stiff carrier secured by a holder to a bracket. The holder allows the carrier to move relative to the bracket. When the centrifugal weights start moving, they become synchronized within a short period of time and generate vibrations which can be used in the desired manner via the bracket.
