<p>PURPOSE:To reduce the weight of a hydraulic circuit and improve the cost performance by restricting a rate of oil required by an accumulator to a minimum, and reducing a reservoir capacity. CONSTITUTION:An inner space of a piston type accumulator is partitioned by means of a slidable piston 03 into an operation oil side part and a gas side part. A stopper 2 is provided on a proper portion of the gas side part in order to restrict sliding of the piston 03 toward the gas side part within a specified range.</p> |
