  • Patent number: 7159575
    Abstract: Surplus fuel returns from an engine into the sub-tank through a bellows pipe. A downstream end of the bellows pipe is supported by a sub-tank lid that closes an opening of a sub-tank. One ends of arms engage with the top of a pump module, which includes a fuel pump. The other ends of arms engage with the outer peripheral wall of the sub-tank. Thereby, the arms connect between the pump module and the sub-tank. Surplus fuel flows into the sub-tank through the bellows pipe, and strikes against the arm. Thereby, return fuel, which comes back into the sub-tank, decreases in kinetic energy. Thus, sound and vapor generated from fuel in the sub-tank can be reduced when return fuel comes back into the sub-tank.

  • Patent number: 7121266
    Abstract: A fuel pump cutoff shuttle valve is located between a multiple fuel pump arrangement. The valve has a first tubular member with a hollow, biased sliding member inside that moves according to the fuel pressures of the pumps. The fuel that flows through the valve member passes out through a valve member central orifice so that the fuel can flow into the second tubular member en route to an engine. When the fuel pressure in a pump greatly exceeds that of another pump on the opposite side of the valve member, the valve member moves and places the valve member central orifice adjacent to the interior wall of the first tubular member, stopping the flow of fuel. Alternatively, the valve member may have an orifice at each end of the valve member to permit a reduced flow of fuel to the engine when fuel is not supplied by the central orifice.

  • Patent number: 6981490
    Abstract: A fuel feed apparatus including a sub-tank is received in a fuel tank having multiple tank sections. Multiple jet pumps respectively transfers fuel received in the tank sections into the sub-tank. Therefore, even if a fuel amount received in a single tank section decreases, fuel can be steadily supplied from another tank section. Intermediately pressurized fuel in a fuel pump is supplied to the jet pumps, so that fuel can be steadily supplied to the jet pumps regardless of fuel consumption amount in an engine. Fuel is drawn from an upstream side of a pressure regulator, and supplied to the jet pump. The pressure regulator has an urging unit, and controls fuel pressure without using a diaphragm. Therefore, the pressure regulator is simplified and downsized.
