Abstract

A filtering device may includes a bag-shaped filter member that is capable of being connected to a fuel inlet port of a fuel pump disposed in a fuel tank in order to filtrate fuel drawn by the fuel pump, and a wall member that is connected to the filter member such that a fuel reservoir portion can be defined above the filter member.

First claim

What is claimed is:

1. A filtering device comprising:
a filter member comprised of two dish-shaped filter elements joined along corresponding welding portions and defining a filtrated interior volume,
a fuel pump disposed in a fuel tank,
piping having a first end in fluid communication with the filtered interior volume, and a second end connected to a fuel inlet port of the fuel pump in order to filtrate fuel drawn by the fuel pump; and
a wall member comprising a lid portion, peripheral walls, and a lower opening,
wherein the peripheral walls of the wall member directly contact the filter member along the welding portions, and seal the lower opening of the wall member to form a fuel reservoir portion above the filter member;
wherein the lid portion has a fuel flow opening that allows the fuel in the fuel tank to flow into the fuel reservoir portion therethrough;
wherein the fuel pump is horizontally disposed on the lid portion; and
wherein the fuel pump is supported on the wall member by a pump receiving portion formed in an upper surface of the lid portion such that the fuel pump is positioned above the fuel reservoir portion.

2. The filtering device according to claim 1 , wherein the lid portion is integrally formed in the wall member.

3. The filtering device according to claim 1 , wherein the fuel pump is arranged so as to be positioned within the fuel reservoir portion in plan.

4. The filtering device according to claim 1 , wherein a pressure regulator controlling a pressure of the fuel fed to an engine is disposed on the lid portion.
