Abstract
Abstract A FIRST MEMBER INCLUDES AN INNER CAVITY CONTAINING A SECOND MEMBER WHICH DIAMETRICALLY IS SLIGHTLY SMALLER THAN THE CAVITY AHD AXIALLY IS SNUGLY RECEIVED IN THE CAVITY. ONE OF THE MEMBERS IS CONNECTED TO A LARGE MASS BACKUP STRUCTURE AND THE OTHER IS FREE FOR ORBITING RADIAL SHIFTING MOVEMENT WITHIN THE LIMITS OF THE RADIAL GAP BETWEEN THE MEMBERS. RADIALLY MOVABLE SEALS CARRIED ONE OF THE MEMBERS DIVIDE THE GAP INTO A PLURALITY OF PULSE CHAMBERS. A SEPARATE BIDIRECTIONAL FLOW PASSAGEWAY LEADS INTO EACH PULSE CHAMBER. FLUID PRESSURE PULSES ARE DISTRIBUTED AROUND THE GAP IN REPETITIVE CYCLIC FASHION FROM PULSE CHAMBER TO PULSE CHAMBER. A RADIAL PISTON TYPE PULSE GENERATOR DIVIDED INTO TWO AXIALLY SPACED SETS OF PISTONS MOVED RADIALLY BY SEPARATE ROTARY CAMS OFFSET AN OPPOSITE SIDES OF A CAM SHAFT. A CUTTING EDGE ON SUCH A FIRST MEMBER, AND MEANS FOR MOVING THE BACKUP STRUCTURE TO ADVANCE THE CUTTING EDGE INTO AN EARTH FORMATION.
