ABSTRACT:
A high-pressure fluid jet valve assembly is disclosed utilizing a double-acting piston actuated by a spool valve to reversibly actuate the valve stem. The valve stem selectively gates high-pressure cutting fluid through a seat arrangement directly into an output expansion section. Directly coupled to the expansion section is a valve head holding a jewel holder used to shape the high-pressure fluid beam for cutting purposes. The valve seal, stem and seat arrangement are designed to prevent leaching of the stem by the effect of high-pressure water, yet allow the cycling time in the order of 25 milliseconds.
