ABSTRACT:
A system for removal of workpiece material with a high velocity jet of working fluid, comprising an ultra-high pressure pump including a plurality of low pressure fluid cylinders and a plurality of high pressure cylinders longitudinally aligned with and adjacent the outer end of each low pressure fluid cylinder and having a high pressure piston reciprocally mounted therein and interconnected to reciprocate with a low pressure piston in an adjacent low pressure cylinder. High pressure valves are provided for each high pressure cylinder including an inlet check valve and an outlet check valve for releasing said working fluid under high pressure. A high pressure manifold is interconnected to the outlet check valves and a conduit carries the high pressure working fluid to a high velocity jet forming nozzle. A suction hood surrounds the nozzle for carrying away material debris removed from the workpiece and a liquid spray is provided to wet the debris removed by the jet and confine the material for pick-up by the suction hood.
