Zusammenfassung:The present invention relates to a pressure control valve of a fuel rail, connected to a fuel rail of an engine to control the pressure of a fuel of the fuel rail. The pressure control valve comprises: a valve main body having an inflow channel through which a fluid flows from the fuel rail, an escape chamber injecting the fluid of the fuel rail via the inflow channel to reduce a ripple inside the fuel rail, and a discharge channel discharging a fluid of the escape chamber to the outside; a first sealing unit opening and closing the inflow channel; and a second sealing unit opening and closing the discharge channel to enable the fluid of the fuel rail to pass through the escape chamber to be discharged to the outside of the valve main body. Therefore, the present invention can selectively perform functions of ripple reduction and ripple decompression in accordance with a system pressure. 본 발명은 엔진의 연료레일에 연결되어 연료레일의 유체압력을 조절하는 연료레일의 압력조절밸브에 관한 것으로, 연료레일로부터 유체가 유입되는 유입유로를 구비하고 유입유로를 통해 연료레일의 유체를 유입하여 연료레일 내부의 맥동을 저감시키는 도피챔버를 구비하며 도피챔버의 유체를 외부로 배출시키는 배출유로를 구비한 밸브몸체, 유입유로를 개폐하는 제1실링부, 및 연료레일의 유체가 상기 도피챔버를 통과하여 상기 배출유로를 통해 상기 밸브몸체의 외부로 배출되게 배출유로를 개폐하는 제2실링부를 포함하여, 시스템 압력에 따라 맥동을 저감기능과 감압기능을 선택적으로 수행할 수 있게 된다.
