Abstract
The device for controlling and actuating a vibrating mechanism, particularly in tampers, comprises a hydraulic pump (12) that drives a hydraulic motor (18), which interacts with the vibrating mechanism (10) while being a part of a hydraulic circuit (16) to which a pressure regulator (22) is connected in the secondary branch (20) and can be controlled by a hydraulic switching device (24). This configuration provides a purely hydraulic solution that does not require electrical current for controlling and switching off the vibrating mechanism.
