た請求項１記載の高圧水発生装置。[Scope of Claim for Utility Model Registration] 1. High pressure cylinders that operate in conjunction with the low pressure cylinders are arranged at both ends of a low cylinder connected to a hydraulic pump via a switching valve, and only feed water is allowed to flow into the water chamber of each high pressure cylinder. In a high-pressure water generator, the hydraulic pump is connected to a nozzle via a high-pressure water check valve and an on-off valve that only allow high-pressure water discharge, and a two-stage flow rate switching type regulator. A high-pressure water generator characterized by being a variable displacement hydraulic pump equipped with a manual handle for adjusting the maximum discharge amount. 2 Two-stage flow rate switching regulators are connected to the tilting section of the variable displacement hydraulic pump, and the maximum tilting amount is regulated by the manual handle for adjusting the maximum discharge amount.The two-stage flow rate switching type regulator is installed in two positions in both the front and rear liquid chambers of the servo piston. 2. The high-pressure water generator according to claim 1, wherein the pump hydraulic pressure and the tank pressure are alternately guided by a switching valve.
