ンダ装置。Inside the basic cylinder, each piston is placed at the base end. A plurality of movable cylinders each having substantially the same effective area on the reciprocating side are fitted in sequence, and the forward and reciprocating oil chambers of each movable cylinder are connected directly or directly to each other. It has a multi-stage double-acting hydraulic cylinder that is indirectly connected to each other, and the forward side oil chamber and the backward side oil chamber are each connected to a directional control valve that selectively connects to a hydraulic power source or an oil tank. , pressure compensation is provided between the double-acting oil chamber and the directional control valve.
A return flow path having an on-off valve is formed between the forward-moving first side oil chamber and the oil tank, and the on-off valve is operated by the multi-stage double-acting hydraulic cylinder. A multi-stage double-acting hydraulic cylinder device that opens only when
