Exhaust bend for internal combustion engine has third shell enclosing second to form fluid heat conducting gap and is connected to fluidtight to inlet and outlet flanges

摘要

The exhaust bend has a multi-shell connecting section between the inlet (2) and outlet (4) flanges. The third shell (8) encloses the second shell (7) on the side opposite the first shell (6) to form a fluid gap (11) and is connected fluidtight to the inlet and outlet flanges. The third shell has a fluid inlet (9) and a fluid outlet (10) which open out into the gap between the second and third shells and to which is connected the inlet and return pipes respectively of a fluid-fed cooling circuit. An Independent claim is included for a procedure for the operation of an exhaust bend in which fluid fed into the gap between the third and second shells forms a heat conducting connection.
