Fuel tank with incorporated deformable reservoir
First Claim
1. A fuel tank for a motor vehicle, comprisinga fuel tank body having a wall defining the fuel tank body, the wall having a closable opening therethrough, a reservoir having first and second ends and a boundary wall and being of smaller size than the tank body and disposed therein and inserted into the tank body through the opening in the wall thereof, means connecting the reservoir to the tank body, and firm components delimiting the reservoir at its first and second ends, the reservoir being deformable at least at portions of the boundary wall thereof in such a way that after the reservoir has been at least partially introduced into the tank body the reservoir experiences a change in shape resulting in an increase in its volume within the tank body and a change in its cross-section such that the largest cross-section of the reservoir in its operative position is larger than the cross-section of the opening in the tank body wall available for insertion of the reservoir, and the deformable wall portions of the reservoir being between components at the ends of the reservoir.

Abstract
A fuel tank for a motor vehicle, comprising a tank body with a smaller reservoir which is arranged therein and which is inserted into the tank body through a closable opening in the wall thereof, and joined thereto. The reservoir is deformable at least in portions of the wall defining same. After the reservoir has been at least partially inserted into the tank body, it undergoes a change in shape resulting in an increase in its volume within the tank body and a change in its cross-section such that the largest cross-section of the reservoir is larger than the cross-section of the opening of the wall in the tank body, that is available for insertion of the reservoir. The reservoir is defined at its ends by rigid components and the deformable wall portion of the reservoir is in the region between those components.

31. A fuel tank for a motor vehicle, comprising
a fuel tank body having a wall defining the tank body, the wall having a closable opening therethrough, a reservoir having first and second ends and a boundary wall and being of smaller size than the tank body and disposed therein inserted into the tank body through the opening in the wall thereof, first and second substantially non-deformable portions at respective ones of the ends of the reservoir, means connecting the reservoir to the tank body, the reservoir being deformable at least at portions of the boundary wall thereof between said first and second portions whereby after the reservoir has been at least partially introduced into the tank body the reservoir can experience a configurational change such that the largest cross-section of the reservoir in its operative position within the tank body is larger than the opening in the tank body wall.
