Abstract: The invention provides a vibrator which may be used to vibrate industrial apparatus such as a conveyor, hopper, bin, screen, shaker table, or to agitate a fluid. The vibrator has a element comprising a concave outer skin on one side and a convex outer skin on the other side which define between them a cavity. The cavity is connected to a hydraulic driving circuit which provides a continuous series of high pressure pulses. Each pulse causes the deformable element to change shape. The continuous application of a series of pulses causes the deformable element to continuously vibrate. The high pressure pulses are generated by creating a water hammer within a conduit by means of a valve which can be rapidly opened and closed to allow fluid to flow through the conduit and then suddenly block the fluid flow. The vibrating apparatus may be used to shake industrial structures such as shaking screens, shaking tables, hoppers, bins or the like.
