Abstract
An improved fuel tank is disclosed. In the fuel tank, a shock-absorbing member comprising a plurality of foam members is mounted to an in-tank functional component provided inside a resin fuel tank body. When the fuel inside the tank sloshes up and down, the fuel strikes the shock-absorbing member, causing the force of the waves to be dispersed, and reducing the fuel sloshing sound created by the sloshing of the fuel.
Claims8
A fuel tank comprising:
- a resin tank body;
- an in-tank functional component provided inside the tank body;
- and
- a shock-absorbing baffle member formed into a shape mountable to the in-tank functional component, said shock-absorbing baffle member comprising a plurality of foam members each having a hollow bore extending through a central portion thereof, wherein the foam members are formed from a foamable fuel-tolerant material and arranged in a sequence on an elongated support member,
- wherein the in-tank functional component comprises a resin pipe member having both ends thereof fixed inside the tank body, and wherein the resin pipe member functions as said elongated support member.

A fuel tank assembly comprising:
- a resin tank body comprising a first chamber having a first opening formed therein, a second chamber having a second opening formed therein and an arcuate connecting channel interconnecting the first and second chambers;
- a fuel supply pump including a supply pump body portion which extends inwardly into the first chamber through the first opening;
- a fuel transfer pump for transferring fuel from the second chamber to the first chamber, the fuel transfer pump including a transfer pump body portion which extends inwardly into the second chamber through the second opening;
- a resin pipe member which interconnects the fuel supply pump to the fuel transfer pump and provides fluid communication there between;
- and
- a shock-absorbing baffle member disposed inside of the resin tank body, said shock-absorbing baffle member comprising a plurality of foam members each having a hollow bore extending through a central portion thereof, wherein the foam members are formed from a foamable fuel-tolerant material and arranged in a sequence on the resin pipe member.
