機。 A cylinder device equipped with a piston having a large-diameter portion and a small-diameter portion, a cam-type switching valve that communicates with the large-diameter piston chamber of the cylinder device and operates in conjunction with the piston rod, and an oil supply line connected to the small-diameter piston of the cylinder device. The small-diameter piston side of the cylinder device is connected to an oil supply line and a hydraulic oil line of an external hydraulic actuator through one-way valves, respectively. The automatic pressure intensifier is characterized in that the cylinder device is in communication with each other, and the piston movement is performed by a pressure difference between a small diameter piston chamber and a large diameter piston chamber, thereby compensating for a pressure drop in the hydraulic oil. .
