ABSTRACT:
An inlet chamber receives fluid from a small high pressure pump, such fluid flowing through a flow restrictor and one-way valve into an accumulator, until very high pressure is established in the accumulator. At the same time, a sealed poppet is pushed against a poppet seat by the high pressure within the inlet chamber to prevent fluid flow into an output chamber coupled to a bore hole. When the high pressure fluid in the accumulator is to be discharged into the output chamber, the inlet chamber is vented to the atmosphere to rapidly separate the poppet from the poppet seat. The poppet has an end portion having an area greater than the sealing area occupied by the poppet seat which permits the fluid under high pressure within the accumulator to rapidly separate the poppet from the valve seat so that a very large fraction of the energy in the accumulator is discharged through the outlet portion of the apparatus, to be injected into a bore hole for the purpose of fragmenting rock or the like.
