  • Patent number: 8820350
    Abstract: Provided is a fuel pump module in which a portion of fuel transmitted from a fuel pump provided in a reservoir or fuel returned from an engine is supplied to a first jet and a second jet and a portion of the fuel is supplied from a first jet tower to a second jet tower through a connection tube connecting the first jet tower and the second jet tower to each other when the returned fuel passes through the first jet and the second jet and is then jetted to each of the first jet tower and the second jet tower to fill an inner portion of the second jet tower with the fuel, such that the fuel in a second space part of a fuel tank is rapidly transmitted, thereby making it possible to stably supply the fuel to the engine.

  • Patent number: 8763589
    Abstract: A fuel pump module including: a reservoir installed in a fuel tank, the reservoir being charged with a predetermined amount of fuel; a fuel pump installed in the reservoir and pumping the fuel contained in the reservoir to an internal combustion engine; a jet pump injecting a fuel jet into the reservoir to thereby introduce the fuel stored in the fuel tank into the reservoir; a guide tube installed on the jet pump and guiding both the fuel jet and the fuel introduced from the fuel tank along with the fuel jet into the reservoir; and a filter unit partitioning the interior of the reservoir into a fuel suction area, into which the fuel is introduced by the fuel pump, and a fuel charging area, which is charged with the fuel from the fuel tank, thus preventing foreign substances from being introduced from the fuel charging area into the fuel suction area.

  • Patent number: 8291946
    Abstract: Provided is an apparatus for sensing a fuel level in a fuel tank for sensing an amount of fuel remaining in the fuel tank mounted in a vehicle. The apparatus for sensing a fuel level according to the present invention senses a residual amount of fuel in a fuel tank by contacting a resistance substrate with a wiper, the apparatus including: a case that forms a sealable filling solution filling space and has a filling solution inlet formed on a top thereof; a stopper that blocks the filling solution inlet formed in the case to seal the filling solution filling space; and a filling solution that is filled in the filling solution filling space to perform an anti-rusting and lubricating function, wherein the resistance substrate and the wiper are disposed in the filling solution filling space.

  • Publication number: 20110174275
    Abstract: Provided is a fuel supply system. The fuel supply system includes a fuel pump module mounted in a fuel tank and including a reservoir having a predetermined amount of fuel filled therein and a fuel pump mounted in the reservoir to suck the fuel filled in the reservoir and supply it to an internal combustion engine; a fuel supply line supplying fuel from the fuel pump module to the internal combustion engine; and a fuel return line returning the fuel from the internal combustion engine to the fuel tank, wherein the inside of the reservoir is provided with a bypass tube connecting the fuel return line to the fuel pump to directly supply the fuel returned through the fuel return line to the fuel pump through the bypass tube.
