Benefits of technology

"The present invention is directed to a fuel pump module for vehicles that can prevent fuel from not smoothly filling in a reservoir due to an orifice action of a jet pump when the vehicle travels a steep slope section. The fuel pump module includes a dual jet system with a main jet pump housing and a sub-jet pump housing. The main jet pump housing has a first jet orifice and a cylindrical check valve sealing part with an anti-siphon check valve assembly. The sub-jet pump housing has a second jet orifice. The bottom side of the reservoir has a coupling groove to be coupled with the top side of the dual jet system. The main jet pump housing and the sub-jet pump housing are mounted opposite each other. The fuel pump module also includes an outlet pipe and an inlet pipe interconnected by a connection tube. The invention prevents engine hesitation and stop phenomena caused by insufficient fuel supply to the engine."

Problems solved by technology

However, a case in which the fuel is not smoothly filled in the reservoir 31 through the jet pump 40 under adverse conditions such as when a vehicle stops on a steep slope in a low fuel state or when a vehicle is sharply turned.
Therefore, the engine hesitation and stop phenomena of the vehicle occur due to the fuel insufficiently supplied to the engine.

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

CROSS-REFERENCE TO RELATED APPLICATIONSThis application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 10-2010-0032704, filed on Apr. 09, 2010, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.TECHNICAL FIELDThe present disclosure relates to 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.BACKGROUNDGenerally, a fuel supply apparatus of a vehicle is a fuel apparatus of a vehicle driven by being supplied with liquid fuel, like a gasoline engine or a diesel engine. The fuel supply apparatus is an apparatus of supplying f...
