Abstract: Apparatus for forming pulsed jets of liquid. A movable cylinder cooperates with a nozzle block to define a compressible charge chamber. A piston within the nozzle block is movable between a firing position, in which it completes the nozzle discharge opening from the charge chamber and a loading position, in which it permits passage of gas to the nozzle discharge opening, thereby removing any liquid remaining therein from the preceding liquid jet pulse. To generate a charge, the piston is moved to the loading position, following which the discharge opening is blown dry and charge material is applied to the charge chamber. An actuating piston is actuated to impact on the cylinder compressing the chamber and expelling the charge through the nozzle as a pulsed liquid jet. A floating check valve permits removal of air entrapped within the charge chamber.

Abstract: An apparatus for, and a method of, boring through earth formations, employing a drill bit which comprises a rotary drill, in combination with a device for producing pulsed jets of liquid under high pressure. The device is arranged to cut and fracture the bottom periphery of the borehole and the drill bit cuts and fractures the bottom of the borehole.
