Abstract

PURPOSE: To prevent a phenomenon of panting operation and improve efficiency of work, by shortcircuiting a forward and return lines in such a manner that working fluid at the discharge side is partially branched into the supply side.
CONSTITUTION: In a forward line 13 and return line 14 in a part 12 of a selector valve 19 that communicates an oil hydraulic pump 9 and oil tank 10, check valves 6, 7 are provided respectively. And, in a forward line 16 and return line 17 in the other part 15, check valves 6, 7 are provided respectively, while said forward line 16 and return line 17 are connected through a check valve 18. A piston in a cylinder 1 moves in the direction of an arrow mark A, if a sufficient amount of working oil is supplied from the oil pressure pump 9, but if this mount is short, the pressure in a circuit in the forward line becomes negative, and working oil in the return line side partially passes through the check valve 18 to flow into the forward line side and supplement the shortage of the supply amount of working oil. In this way, operation of an actuator of the cylinder 1 or the like can be smoothly performed.
