Abstract
A high-pressure waterjet cutting system includes a pump operable to produce a flow of pressurized hydraulic fluid, a piston receiving the flow of pressurized hydraulic fluid and reciprocating in response to a pressure differential produced by the flow of pressurized hydraulic fluid, and an intensifier connected to the piston and operable to produce a high-pressure flow of water in response to reciprocation of the piston. A valve is positioned to receive the flow of hydraulic fluid and is movable between a first position in which the pressure differential is a first value and a second position in which the pressure differential is a second value less than the first value.
