An ultra high pressure water jet cutting nozzle is disclosed which comprises a lightweight poppet valve assembly coupled by a lost motion connection to a valve actuator. The poppet valve assembly seals directly to the jet-forming element of the nozzle insuring continuous high pressure fluid in the system at all times. The maintenance of constant high fluid pressure in the system protects the supply tubing of the system against damage due to pressure waves generated by repeated opening and closing of the valve assembly. The maintenance of continuous high fluid pressure also prevents dislodgement of the jet-forming element of the nozzle. |
