Abstract (en)

[origin: EP1455079A2] The exhaust gas cooling device has a heat transfer region (2) for transfer of heat from the exhaust gas to a cooling medium, positioned between an exhaust gas entry region (3) and an exhaust gas exit region (4). A setting element, for control of the exhaust gas flow through an integrated bypass channel (7) for the heat transfer region is provided by rotary ball (14) provided with a through flow channel, positioned infront of the entry opening (15) of the bypass channel or after its exit opening. The outside surface of the ball has at least one flow region, for passage of the exhaust gas through the heat transfer region in a second rotary position, in which the bypass channel is closed by the ball body.
