Motor vehicle fuel tank component assembly has one component that expands on contact with hydrocarbon fuel

摘要

An assembly of two or more components that will be in contact with a hydrocarbon fuel, such as the shell (1) of a tank or a support (80) for an inner component, each with a fixing element (90, 98) to hold them together, has at least one of the components made from a material that expands under the action of the hydrocarbon to reinforce the fixing. An assembly of two or more components that will be in contact with a hydrocarbon fuel, such as the shell (1) of a tank or a support (80) for an inner component, each with a fixing element (90, 98) to hold them together, has at least one of the components made from a material that expands under the action of the hydrocarbon to reinforce the fixing. The support can be joined to the shell by welding, and the attached component can be, e.g. a valve (81) or fuel gauge.
