Abstract:
PCT No. PCT/JP94/00834 Sec. 371 Date Apr. 5, 1995 Sec. 102(e) Date Apr. 5, 1995 PCT Filed May 25, 1994 PCT Pub. No. WO94/28303 PCT Pub. Date Dec. 8, 1994A superhigh pressure generator system is provided which comprises first, second and reserve boosters 1, 2, 3 which are respectively provided with a plunger chambers 4a, 4b, 4c within single rod-type oil hydraulic cylinders 7a, 7b, 7c on the plunger side and are operative to pressurize water sucked into the respective plunger chambers to superhigh pressure, the boosters being connected in parallel each other to a water discharge line 9 via check valves 6a, 6b, 6c respectively. First, second and reserve 3-position directional control valves 13, 14, 15 are interposed between the oil hydraulic cylinders 7a, 7b, 7c of the respective boosters on one hand and first and second oil hydraulic pumps 11, 12 on the other hand so as to permit a reciprocating motion of the oil hydraulic cylinders. On-off valves 20, 21, 23, 22 are respectively provided on discharge lines 17, 18, 19, 16 which connect the three-position directional control valves 13, 14, 15 to the first and second oil hydraulic pumps 11, 12. In this way, the use of a single acting oil cylinder for reserve purposes enables continued operation in the event of seal failure and provides for cost and size reduction.
