圧駆動ピストンの往復動切換え装置。In a reciprocating motion switching device for a double-tube hydraulically driven piston, a small cylinder is integrally provided at the end of the same side of each cylinder and is smaller than the outer diameter of the piston of the cylinder and larger than the outer diameter of the piston rod. A cylindrical portion that fits into the small cylinder without a gap is protruded from the end face of the small cylinder, and a pilot valve that is switched by pressure fluid from the small cylinder and a pilot operated valve that is switched by switching the valve are provided in the piping. In addition to supplying and discharging fluid to each fluid pressure cylinder through a pilot operated valve, the pipes connecting each small cylinder and the pilot valve are branched to connect these pipes to both cylinders. 1. A reciprocating switching device for a double-tube fluid pressure driven piston, characterized in that the two are connected via a check valve in between, and fluid is supplied to the small cylinder after switching the pilot valve.
