とする連続形増圧器。 Cylindrical guides are protruded from the inside of both end faces of a cylinder tube with both ends closed, and slide on the inner circumferential surface of the cylinder tube and the outer circumferential surfaces of both guides to reciprocate within the cylinder tube. A cylindrical piston is provided inside the piston, and a partition wall is provided inside the piston to divide the inside of the piston to form a pair of oil chambers, and a partition wall is provided inside the piston to form a pair of oil chambers. A port is provided in the middle of the cylinder tube to constantly communicate the oil chamber on the outer periphery of the piston with the tank, and each pilot pipe of the pilot type switching valve that reciprocates the piston is communicated with the pump circuit by switching the port. and a cylinder tube that connects each pilot pipe to a pair of ports that communicate with an oil chamber on the outer periphery of the piston provided in the cylinder tube, and that communicates with one pilot pipe when the piston moves to one end. The port of the cylinder tube is blocked by the piston and the switching valve is switched in the opposite direction, and when the piston moves to the other end, the port of the cylinder tube that communicates with the other pilot pipe is blocked by the piston and the switching valve is switched. A continuous pressure intensifier characterized by being able to switch back to its original position.
