段に圧力スイツチを用いた請求項１記載の往復動
式増圧器の余剰給水防止装置。[Scope of Claim for Utility Model Registration] 1. A low-pressure cylinder connected to a hydraulic pump via a switching valve is provided with high-pressure cylinders that operate in conjunction with the low-pressure cylinders at both ends, and only high-pressure water is allowed to be discharged from the water chamber of each high-pressure cylinder. In a reciprocating pressure booster that connects a high-pressure water check valve that allows water to flow in, and a water supply check valve that only allows water inflow, there is an accumulator in the flow path that connects the water supply check valve and the water supply pump, and the set pressure is the same as the set operating pressure of the accumulator. In addition to installing a relief valve whose pressure is higher than the upper limit pressure of the range, the water supply pump control operates when the water supply pressure falls to the lower limit pressure of the set operating pressure range of the accumulator, and stops operation when the upper limit pressure is reached. A surplus water supply prevention device for a reciprocating pressure booster, characterized by comprising a means. 2. The surplus water supply prevention device for a reciprocating pressure intensifier according to claim 1, wherein a pressure switch is used as the water supply pressure detection means in the water supply pump control means.
