    摘要： A HOLLOW EARTH WORKING IMPLEMENT HAS AN OPENING WHICH IS CLOSED BY THE EARTH IT ENGAGES AND WHICH COMMUNICATES WITH A COMBUSTION CHAMBER SUPPLIED AT INTERVALS WITH A COMBUSTIBLE MIXTURE IGNITED BY A SPARK PLUG, VALVE MEANS BEING PROVIDED TO AUTOMATICALLY CONTROL THE FLOW OF THE COMBUSTIBLE MIXTURE TO THE COMBUSTION CHAMBER AND VALVE CONTROL MEANS CARRIED BY THE IMPLEMENT BEING ACTUATED BY THE PRESSURE OF THE SOIL DURING MOVEMENT OF THE IMPLEMENT TO OPEN THE VALVE AND DISCHARGE THE MIXTURE INTO SAID CHAMBER. THE PRESSURE EXERTED BY THE EXPANDING IGNITED MIXTURE IS DIRECTED THROUGH SAID OPENING TO LOOSEN AND MOVE THE DIRT ALLOWING THE VALVE TO CLOSE.

    摘要： An improvement in an apparatus for creating repetitive explosions from an outlet of a combustion chamber by actuating a digging assembly by the explosive pressures to loosen and break up hard materials. The use of piston-driven digging teeth for loosening and breaking up material formations both prior to and simultaneously with material displacement by repetitive explosive blasts. An apparatus positioning locking assembly including a piston-driven pin actuated by the repetitive explosive blasts into position for holding the apparatus in position and which is actuated either prior to or simultaneously with the material displacement blasts and digging assembly actuation.

    摘要： A highly responsive valve for exhausting high pressure combustion gases from a closed combustion chamber upon the occurrence of a predetermined pressure is disclosed. A valve housing defines a cylindrical pressure chamber adapted for connection to a combustion chamber. A cylindrical valve sleeve is reciprocably guided along the chamber interior wall from a first position blocking directionally oriented outlet ports in the chamber to a second position opening the outlet ports to rapidly discharge combustion gases from the pressure chamber. The lower edge of the sleeve seats against a cover plate in the first position and defines an annular pressure chamber with the grooved seat. A pilot valve houses a reciprocable piston which controls communication between the pressure chamber and the valve chamber. The pilot valve piston is pressure biased to a position blocking communication between the pressure and valve chambers and the pilot valve piston shifts in response to a predetermined pressure rise in the valve pressure chamber to communicate the annular pressure chamber with high pressure to cause the valve sleeve to be rapidly accelerated to a full open position. Ring springs limit the sleeve travel and absorb the energy of the accelerating sleeve. The valve sleeve is provided with an internal shoulder area exposed to the pressure chamber so that combustion chamber pressure prior to ignition acts to positively hold the sleeve seated. Lubricating fluid is introduced in a valve guided slot of the valve sleeve and valve housing wall surfaces so that lubricant is prevented from entering the interior pressure chamber.

    摘要： An air control system for an apparatus displacing material by combustive explosions insuring that the air valve leading to the combustion chamber is closed during combustion. An air supply system for a combustive apparatus for displacing material in which the charging pressure of the air in the combustion chamber may be selected and controlled. An air control system for controlling the air inlet valve to the combustion chamber of an explosive material displacing apparatus having a relief valve with means for adjusting the pressure at which the relief valve opens with a control valve connected to and responsive to the relief valve and an air control line connected to the air supply in which the flow of air therethrough is controlled by the control valve, and a piston connected to the air inlet valve and exposed on one side to the pressure in the air control line whereby pressure passing through the control line acts on the piston in a direction to close the valve, and air bleed means connected to the air control line for relieving the air control line to allow the air inlet valve to be actuated. The air control system controlling the air supply valve to allow the full air supply pressure to be built up before charging the combustion chamber with air thereby allowing the air supply system to charge air to the combustion chamber at a higher charging rate.
