Abstract

Provided is a dual jet system mounted at a bottom end of a reservoir in a fuel pump module, and more particularly, to a fuel pump module mounted with a dual jet system capable of preventing a phenomenon that fuel is not smoothly filled in a reservoir due to fuel inclined to one side caused by an inclination of a fuel tank when a vehicle travels a steep slope section by mounting two jet pumps at both edges of a bottom end of a reservoir.

Description

technical field [0001] The present invention relates to a dual-nozzle system arranged on the lower end of the accumulator of a fuel pump module, and in more detail, relates to a fuel pump module equipped with a dual-nozzle system, which is provided with two nozzle pumps at the edge positions on both sides of the lower end of the accumulator , when the vehicle is running in a steep slope area, it can prevent the fuel from tilting to one side due to the tilt of the fuel tank, which will cause the fuel to be unable to be smoothly poured into the storage tank. Background technique [0002] Generally speaking, the fuel supply device of the vehicle supplies the required fuel to the fuel device of the vehicle, such as a gasoline engine or a diesel engine, which is driven by liquid fuel supply, so that the engine can achieve the best combustion state under any operating conditions. , plays an important role in affecting the output power or thermal efficiency of the vehicle.
