  • Assembly, comprising an exhaust gas turbocharger, an intercooler and a charge-air line
    Patent number: 7699036
    Abstract: To provide an assembly, comprising an exhaust gas turbocharger and an intercooler for an internal combustion engine and a hot-side charge-air line connecting the exhaust gas turbocharger to a charge-air inlet of the intercooler, which assembly allows the movements to be equalised between the exhaust gas turbocharger and the intercooler and is simple to produce and assemble, it is proposed that the hot-side charge-air line comprises a one-piece plastics material tube which is formed from a material containing polytetrafluoroethylene and/or modified polytetrafluoroethylene and has at least one flexible zone.
