PCT No. PCT/JP93/01255 Sec. 371 Date Apr. 29, 1996 Sec. 102(e) Date Apr. 29, 1996 PCT Filed Sep. 6, 1993 PCT Pub. No. WO94/28315 PCT Pub. Date Dec. 8, 1994A hydraulic source(20) comprises a hydraulic pump(62) driven by a motor(61), which operates based on the power and control data from a non-contact power feeding apparatus(30); a hydraulic tank(63); a solenoid valve(64); a relief valve(65); a hydraulic pressure gauge(66); a pilot check valve(67) for clamping and a pilot check valve(68) for unlocking that are interposed between the solenoid valve(64) and hydraulic cylinders(41a to 41d); a pressure switch(69) for clamping which is inserted into a piping for connecting the pilot valve(67) and the hydraulic cylinders(41a to 41d); and an pressure switch(70) for unclamping which is inserted into a piping for connecting the pilot check valve(68) and the hydraudic cylinders(41a to 41d). This hydraulic source is combined with a hydraulic machine for applications where jig or jigs move freely to promote automation of machining, assembly and inspection of workpieces on a moving body.
