Abstract
Fuel tank made of thermoplastic material comprising baffle components provided therein in the form of at least one baffle element (2) comprising at least one wall portion (4) which is clamped approximately centrally and/or at the end, so that said wall portion may perform relative movements in relation to the tank, caused by splashing movements of the fuel, at least one fastening foot being provided for the clamping, the base thereof being provided with at least one through-hole, through which the fastening foot is riveted and/or welded to the tank wall (2).
Claims20
A fuel tank comprising:
- baffle components in the form of at least one baffle element within a volume of the fuel tank, wherein the fuel tank is a thermoplastic fuel tank,
- the at least one baffle element comprising at least one wall portion retained to a wall of the tank by at least one fastening foot,
- wherein the at least one wall portion deforms in response to movements of fuel in the tank,
- wherein the at least one fastening foot is fastened to the at least one wall portion of the baffle element,
- wherein a base of the fastening foot is provided with at least one through-hole, through which the fastening foot is riveted and/or welded to the wall of the tank,
- wherein the wall portion of the baffle element comprises an elastically deformable wing retained in a region of retention thereof by the fastening foot such that, in the region of retention, deformability of the wing is restricted,
- wherein the baffle element is configured such that, in its entirety, the baffle element extends only over one part of an inside height and only over one part of an inside width of the tank volume, and
- wherein the fastening foot and the wall portion of the baffle element are formed of thermoplastic material, the fastening foot and/or the thermoplastic material of the fastening foot having a greater bending stiffness than that of the wall portion and arranged such that, when fuel is in the tank, the thermoplastic material of the fastening foot is exposed to the fuel within the tank.

A fuel tank comprising:
- baffle components in the form of at least one baffle element within a volume of the fuel tank, wherein the fuel tank is a thermoplastic fuel tank,
- the at least one baffle element comprising at least one wall portion retained to a wall of the tank by a fastening foot fastened to a region of an inner side of the wall of the tank,
- wherein the at least one wall portion deforms in response to movements of fuel in the tank and, when fuel is in the tank, the inner side of the wall of the tank is exposed to the fuel,
- wherein a base of the fastening foot is provided with at least one through-hole, through which the fastening foot is riveted and/or welded to the wall of the tank,
- wherein the wall portion of the baffle element comprises an elastically deformable wing retained in a region of retention thereof by the fastening foot such that, in the region of retention, deformability of the wing is restricted,
- wherein the baffle element is configured such that, in its entirety, the baffle element extends only over one part of an inside height and only over one part of an inside width of the tank volume, and
- wherein the fastening foot and the wall portion of the baffle element are formed of thermoplastic material, the fastening foot and/or the thermoplastic material of the fastening foot having a greater bending stiffness than that of the wall portion and arranged such that, when fuel is in the tank, the thermoplastic material of the fastening foot is exposed to the fuel within the tank.
