The piston parts of a pair of high-pressure cylinders installed opposite to each other on the pressure intensifier body are connected via a drive shaft, and a gear rotatably supported on the pressure intensifier body is screwed into a ball screw part provided on this drive shaft. This gear is connected to a servo motor that rotates in the opposite direction every time a predetermined period of time elapses, and the liquid chamber of each high-pressure cylinder is connected to a hydraulic pump via a check valve that allows fluid to flow into the liquid chamber. A reciprocating pressure intensifier characterized in that it is connected to an injection nozzle via a check valve that allows fluid to flow out from the liquid chamber.
