Method and apparatus for using a high-pressure fluid jet

An apparatus for generating a high-pressure fluid jet, the apparatus comprising:

• pressure means for increasing a pressure of a fluid and generating a high-pressure fluid;
• an accumulator having a high-pressure chamber, a gas chamber and a discharge port in communication with said high-pressure chamber, storage of said high-pressure fluid in said high-pressure chamber increasing a gas pressure of a gas within said gas chamber;
• accumulator discharge means for discharging said high-pressure fluid from said high-pressure chamber;
• an injection nozzle having a nozzle body forming a nozzle cavity, transport means for transferring said high-pressure fluid from said high-pressure chamber to said injection nozzle;
• jet means for forming a high-pressure fluid jet within said injection nozzle;
• mixing means for combining a material within said high-pressure fluid jet;
• and
• discharge means for issuing a high-pressure combined fluid and material jet from said injection nozzle.

A method for generating a high-pressure fluid jet, the method comprising the steps of:

• (a) increasing a pressure of a fluid and generating a high-pressure fluid;
• (b) storing the high-pressure fluid within a high-pressure chamber of an accumulator;
• (c) discharging the high-pressure fluid through a discharge port of the accumulator which is in communication with the high-pressure chamber by decreasing a volume of the high-pressure chamber and opening a valve downstream of the discharge port;
• (d) transporting the high-pressure fluid into an injection nozzle and forming the high-pressure fluid jet;
• (e) combining a material with the high-pressure fluid jet;
• and
• (f) discharging a high-pressure combined fluid and material jet from the injection nozzle.
