  • Exhaust gas heat exchanger and bypass assembly
    Patent number: 7264040
    Abstract: An exhaust gas heat exchanger and bypass has an intake manifold, an outlet manifold, a duct for a heat exchanger, and a bypass duct. The heat exchanger duct and the bypass duct run in parallel between the intake manifold and the outlet manifold and are sealingly connected to the outlet manifold. The heat exchanger is arranged in the interior of the heat exchange duct such that the intake side of the heat exchanger is sealingly connected to the heat exchanger duct and the outlet side of the heat exchanger is slideably received in the heat exchanger duct to allow thermal expansion of the heat exchanger relative to the heat exchanger duct.
