Problems solved by technology

[0003] However, when the motor vehicle is running on a sloping or rough road, the fuel stored in the fuel tank is driven to the corner of the fuel tank, thereby requiring an additional fuel suction device driven by the fuel pump
[0004] Therefore, the internal structure of the fuel tank becomes complicated due to the extra inhaler and the connection means for connecting the fuel inhaler and the fuel tank assembly, making it difficult to assemble the fuel tank assembly

Abstract

A fuel pump assembly mounted in a fuel tank for sending fuel to a fuel injector includes a driving means for supplying a driving force for sending or returning fuel, a reservoir for temporarily reserving fuel from the fuel tank through a check valve mounted on a bottom portion thereof, a first fuel suction device for drawing fuel reserved in the reservoir, a return pipe for returning fuel from the fuel injector to the reservoir, a second fuel suction device for drawing fuel stored in the fuel tank, and a Z-nozzle portion of which an outlet is connected to a bottom portion of the reservoir. The second fuel suction device and return pipe are connected to an inlet of the Z-nozzle portion.

Description

technical field [0001] The present invention relates to a fuel pump assembly installed in a fuel tank for delivering fuel in the fuel tank to the injector nozzles, and more particularly to a fuel pump assembly for stably pumping fuel as it is driven to the corners of the fuel tank. Fuel pump assembly that feeds the injectors. Background technique [0002] Generally, a fuel pump assembly installed in a fuel tank that stores fuel includes a fuel pump and a fuel reservoir, wherein the fuel pump is used to send fuel from the fuel tank to the fuel injector and return fuel from the fuel injector to the fuel tank, The oil reservoir is installed in the fuel tank for temporary storage of fuel. [0003] However, when the motor vehicle runs on an inclined or rough road, the fuel stored in the fuel tank is driven to the corner of the fuel tank, thereby requiring an additional fuel suction device driven by a fuel pump. [0004] Therefore, the internal structure of the fuel tank becomes...
