High pressure cylinders that operate in conjunction with the low pressure cylinders are arranged at both ends of a low cylinder connected to a pressure source via a switching valve, and only high pressure water is allowed to be discharged from the water chamber of each high pressure cylinder. It is equipped with multiple reciprocating pressure intensifiers, each consisting of a high-pressure water check valve connected to a high-pressure water check valve that allows only low-pressure water to flow in, and a water supply check valve that only allows low-pressure water inflow. A high-pressure water generator characterized by communicating with a water supply check valve of a reciprocating pressure booster on the side. 2. Claim 1, wherein the high pressure water check valve of the reciprocating pressure intensifier on the low pressure side and the water supply check valve of the reciprocating pressure intensifier on the high pressure side are connected via an accumulator.
High pressure water generator as described. 3 Claim 1 in which the pressure amplitude of the reciprocating pressure intensifier on the high pressure side is narrower than the pressure amplitude of the reciprocating pressure intensifier on the low pressure side.
Or the high pressure water generator according to 2.
