Abstract
In the fuel tank, a tank wall providing a tank chamber is formed by blow molding. A tank partition is disposed in the tank chamber. The tank partition is positioned in a direction substantially perpendicular to a longitudinal direction of the tank wall, and is clamped between the opposite inner surfaces of the tank wall. A functional component is attached to the tank partition.
Claims21
A fuel tank comprising:
- a tank wall forming a tank body;
- a support member formed within said tank body, the support member including tank partitions disposed;
- and
- functional components which are integrally mounted with said support member inside said tank body;
- a coupling member disposed in said tank body and extending in a longitudinal direction of said tank, and wherein said coupling member couples said tank partitions to each other;
- wherein said support member is clamped in a vertical direction of the tank wall between upper and lower inner surfaces of the tank wall, and
- the tank wall is formed by blow molding of a resin, so that the tank partition is clamped between opposite inner surfaces of said tank wall in a direction substantially perpendicular to a longitudinal direction of said tank body.

A fuel tank comprising:
- a tank wall forming a tank body;
- a support member formed within said tank body;
- and
- functional components which are integrally mounted with said support member inside said tank body;
- wherein said support member is clamped in a vertical direction of the tank wall between upper and lower inner surfaces of the tank wall;
- a connecting unit which connects said functional component housed in said tank body to external through a connecting opening formed in said tank wall, said connecting unit including
- an external unit having a lid which is thermal-welded to said tank wall to thereby close up said connecting opening, and an outside pipe which penetrates said lid and is connected to external, and
- an internal unit having an inside pipe which is connected to said outside pipe, and an lifting mechanism which is attached to said support member and supports said inside pipe in a raiseable and lowerable manner.
5 more elements
A fuel tank comprising:
- a tank wall forming a tank body;
- a support member formed within said tank body, the support member being a columnar module which is upstandingly disposed between upper and lower inner surfaces of said tank wall so as to enhance vertical rigidity of said fuel tank;
- and
- functional components which are integrally mounted with said columnar module inside said tank body;
- wherein said support member is clamped in a vertical direction of the tank wall between upper and lower inner surfaces of the tank wall.
