Abstract

An intensifier for delivering ultra high pressure water to a cutting head of a water jet cutting apparatus. The intensifier has a power piston and cylinder assembly connected to piston members extended into pumping chambers in housing located at opposite ends of the piston and cylinder assembly. Inlet poppet valves located in the pumping chambers control the flow of water from inlet passages into the pumping chambers. Outlet poppet valves allow ultra high pressure water to be pumped out of the pumping chamber into an accumulator fluidly connected to the cutting head. Hydraulic fluid under pressure is sequentially directed to opposite ends of the piston and cylinder assembly with a solenoid operated reversing valve. Limit switches operable in response to movement of the piston members control the reversing valve. Linear motion transfer mechanisms are moved with ramps on the piston members to actuate the limit switches to control the reciprocating action of the piston and cylinder assembly.
