Abstract

PURPOSE: To prevent a trouble of shock when overloaded, by providing a small through hole, linked to at least one of the through holes in case and balance piston, in a position corresponding to the rear end part of stroke of the balance piston.
CONSTITUTION: In case with a hydraulic cylinder 9 contracted, if opened a return oil piping system by shifting the spool of a changeover valve 12 rightward, a discharged oil from the hydraulic cylinder 9 is returned to an oil tank 13 through a flow outlet port 10, fixed orifice 18, hollow part 17, main through hole 15, through hole 6, link passage 11 and changeover valve 12. In a position of the rear end part of a blance piston 14, a clearance part, constructed by the through hole 6 and a fine through hole 16A, is narrowed, and its fluid passing area can be reduced at a very little factor of decrease in a range of displacement of the balance piston made corresponding to a length of the fine through hole 16.
