Abstract

A vibrator device is provided in which the actuator rod of a hydraulic ram or jack is rapidly reciprocated, automatically, by means of a hydraulic control circuit which includes a pump, a plurality of connecting conduits, and an oscillating distributor or valve which, under the influence of fluid pressure in the various lines of the circuit, alternately allows pressurized fluid to be supplied to the pressure chamber of the ram or to the reservoir of the circuit, thereby to reciprocate the actuator rod of the jack.
