Description: |
| "In systems requiring high-pressure fluids, for example, water jet cutting or drilling, it is common to use an intensifier that receives fluid, e.g., water, from a low-pressure source and increases the pressure of the fluid to the desire pressure. A typical intensifier will include a low-pressure or working cylinder with a double-acting piston therein, the low-pressure cylinder having opposing high-pressure barrels affixed to it. A high-pressure piston is slidably mounted within each of the high-pressure barrels and the high-pressure pistons are attached to the low-pressure piston such that the high-pressure pistons reciprocate in unison with the reciprocation of the low-pressure piston. A working fluid, such as oil, is alternately pumped into the opposite chambers of the low-pressure cylinder to provide a reciprocal motion of the low-pressure piston and low-pressure water is alternately fed into the opposing high-pressure barrels to be compressed and forced from the cylinder by the high-pressure piston acting in conjunction with the low-pressure piston..." The goal of the patent is to improve on the mechanism of patent 4,029,440 in minimizing the shock at the moment of direction reversal of the high-pressure pistons. |
