摘要： PURPOSE:To obtain a big amount of force by an inverse motion of a piston when a liquid pressure exceeds a prescribed level at the end position of stroke, by lnking the third pilot room of a three-position changeover valve to a liquid pressure source, and to the return line through changeover and sequence valves that open at a prescribed value of liquid pressure. CONSTITUTION:One of liquid chambers 2, of a differential cylinder 1 for an object 10 to be hit is connected to an oil pressure source 5 through pipe lines 3, 4 and the other liquid chamber 6 is selectively connected to the pipe line 4 or a return path 22 through a three-position changeover valve 8. Here a pilot chamber 18 of the changeover valve 8 and the return path 22 are linked by a path 21 in which a throttle valve 20 is intermediately installed. At a position upstream the throttle valve 20 of the above path 21 is placed a two-position changeover valve 24 that links the upstream side of the throttle valve 20 to the pipe line 3 at a prescribed position of a piston rod 11. A pilot chamber 27 is connected to the pipe line 4 through a throttle valve 28. the pilot chamber 27 is also connected to the path 22 through a changeover valve 31, which opens when the upstream pressure of the throttle valve 20 exceeds a prescribed level, and a sequence valve 33, which opens when a pressure in the pipe line 3 exceeds a prescribed level.

摘要： PURPOSE:To remarkably enhance the kinetic energy of a cylinder and piston with less expensive means by increasing the set pressure of a sequence valve and at the point for turning the piston as high as possible. CONSTITUTION:A 3-port 2-position control valve 8 is switched at its functional position A by the hydraulic liquid operating at a pilot chamber 18 to cause the piston 30 to move rightwardly as shown. The hydraulic pressure in the main conduit 3 is lower than the set pressure of a sequence valve 23 to stop the communication of the passage 22 with the passage 24. When the piston 30 is moved to its uppermost limit position, an oil chamber 14 communicates via annular groove 12 with an oil chamber 15 to allow the passage 24 to be communicated with a tank (not shown). Since the passage 22 is stopped communication with the sequence valve 23 via the passage 24, the valve 8 is operated still at the functional position A. Accordingly, the hydraulic pressure is gradually increased in the accumulator 29 to switch to the functional position B at the sequence valve when the hydraulic pressure exceeds the set pressure of the valve 23.
