Abstract (en)

[origin: WO2008128619A1] Disclosed is a vibrator (2) for a vibration plate used for compacting ground. Said vibrator (2) comprises two parallel shafts (5a, 5b) which are coupled to be rotatable in opposite directions and on each of which at least one unbalanced mass (6a, 6b) is disposed. A phase adjusting mechanism (7) is used for modifying the phase angle of the two unbalanced masses (6a, 6b) relative to each other. In order to do so, the actual phase angle of the two unbalanced masses (6a, 6b) is detected with the help of proximity sensors (10). A regulating device (8) compares the actual phase angle with a desired phase angle that is predefined by the operator and controls the phase adjusting mechanism (7) in such a way that the difference between the actual phase angle and the desired phase angle is minimal.
