動式増圧装置。[Claim for Utility Model Registration] By switching the supply and discharge direction of low-pressure, large-volume fluid from a pressure source using a switching valve, small-diameter pistons are integrated on both sides of a reciprocating large-diameter piston, and the large-diameter piston In a reciprocating pressure booster that continuously discharges high-pressure, small-volume fluid through the reciprocation of a small-diameter piston as the small-diameter piston moves, the small-diameter piston is moved toward the large-diameter piston in the axial direction of the piston. An extending communication groove is formed, and when the small-diameter piston reaches a high-pressure fluid discharge side stroke end, two oil grooves communicated by the communication groove are formed in each small-diameter cylinder of the small-diameter piston, and the switching an inner diameter pilot chamber of the valve communicates with one oil groove in each of the small diameter cylinders, and the remaining oil groove in one of the small diameter cylinders is connected to the pressure source for discharging low pressure fluid;
A reciprocating pressure booster, characterized in that the remaining oil groove in the other small diameter cylinder is communicated with the small diameter pilot chamber of the switching valve and is open to a hydraulic tank.
