Abstract
An exhaust gas flow control valve apparatus comprising a rotary valve shaft extending across the exhaust passage in the exhaust housing. The shaft has an end portion projecting from the exhaust housing. A bimetallic element is mounted on the end portion of the shaft. A hollow collar is sealingly fitted onto the end portion of the shaft. A compression spring is arranged at one end of the shaft, so as to urge the hollow collar against the wall of the exhaust housing, for preventing leakage of the exhaust gas.
