したシリンダの油圧回路。 In a hydraulic circuit that connects a double-acting cylinder 1 and a single-acting cylinder 2 with a conduit and causes the single-acting cylinder 2 to operate synchronously by the movement of the double-acting cylinder 1, from the inner diameter area S1 of the double-acting cylinder 1, The area obtained by subtracting the cross-sectional area S2 of the piston rod 11 of the cylinder 1 is equal to the inner diameter area S3 of the single-acting cylinder 2. The port 13 on the piston protruding side of the double-acting cylinder 1 and the single-acting cylinder 2 are connected by a second pipe line 5, and the first pipe line 4 is provided with a branch pipe line 40 communicating with the oil tank 6. The branch pipe 40 is provided with a pilot operating valve 8 that closes the branch pipe 40 when the pressure in the second pipe 5 becomes just before negative pressure, and an on-off valve 42 is provided upstream of the pilot operating valve 8. Hydraulic circuit of the cylinder.
