Valve system of fuel pump for vehicle
A valve system of a fuel system for a vehicle may close a jet pump-side flow path when a pressure of fuel supplied from a fuel pump to an engine is lower than a prescribed fuel pressure at engine start-up, and open the jet pump-side flow path when the pressure of fuel is equal to or higher than the prescribed fuel pressure at the engine start-up, thereby improving cold startability of an engine, and may also allow the jet pump-side flow path to be kept in an opened state between a low load region and a high load region of the engine after the engine start-up, thereby smoothly keeping a function of the jet pump after the engine start-up.
