Abstract: A vibratory roller includes a vibrator operably connected to a rotatable compacting roll. The vibrator is comprised of a rotatable shaft mounted co-axially to the roll and a casing mounted on the shaft and including a chamber and an eccentric mass within the chamber the mass being transversely displaceable in the chamber. Movement of the mass within the chamber provides a variable amplitude for the vibrations induced thereby. The movement of the mass is caused by centrifugal force which urges the mass radially outwardly against a fluid storage space radially outwards of the eccentric mass in the chamber, such chamber in turn communicates through a port with a portion of the chamber radially inwards of the eccentric mass. Fluid thus flows from the radially outwards storage space through the port to the radially inwards storage space and the eccentric mass moves radially outwards until the eccentric mass closes off the port.
