Abstract:
1. A pressure intensifier system adapted to increase the pressure of an operating fluid, the pressure intensifier comprising, a) a pressure cylinder having a first region, a central region and a second region where the lateral direction from the central region to the first region indicates a first direction and an opposing lateral direction from the central region to the second region indicates a second direction, the pressure cylinder having an interior surface, a high pressure passage, and an exit passage; b) a piston assembly comprising, c) a pressure distributor system positioned in the pressure cylinder comprising, d) a pressurizing system having a first line portion that is in communication with the first laterally outer subchamber and the second laterally outer subchamber where a check valve system allows unidirectional flow to the first or second laterally outer subchambers; whereby the piston assembly is adapted to oscillate to alternately displace operating fluid contained therein the first laterally outer subchamber and the second laterally outer subchamber to deliver the operating fluid under intensified pressure to the high pressure receiving member whereby a portion of this fluid is directed to the high pressure passage of the pressure cylinder; e) the second biasing member positioning the first valve at the first position of the first valve by employing stored energy of the second biasing member; and f) the second biasing member having a higher spring constant than the first biasing member whereby when the second biasing member positions the first valve to the first position of the first valve, the first biasing member stores potential energy therein.
