ABSTRACT:
In an earth boring device of either the impact ram or static type wherein the device is driven forwardly either by the impacts of an impact piston or by a forward pressure exerted on the device through a rod, directional control of the device is achieved by arranging a plurality of pressure fluid ejecting nozzles on the head of the device symmetrically with respect to its longitudinal axes, and by individually controlling the pressure and/or amount of pressure fluid supplied to each nozzle to deflect the device in one direction away from what would otherwise be its forward drive path.
