<p>PURPOSE:To maintain the constant relative position between a valve apparatus and a valve operating apparatus even if an exhaust pipe is thermally deformed, by installing the valve apparatus which utilizes the exhaust gas inlet-side edge surface of a turbine casing as valve seat surface and the valve operating apparatus onto the exhaust pipe side. CONSTITUTION:A valve apparatus 6 is set at the valve closing position shown by the full line and the valve opening position shown by the chain line, and exhaust gas is introduced only into an exhaust gas passage 27 when the valve apparatus 6 is at the valve closing position, which at the valve opening position, exhaust gas is introduced into the both exhaust gas passages 27 and 28. At the valve closing position, a valve piece 61 is attached onto the valve seat surface 33 of a turbine casing 21. A valve operating apparatus for operating the valve apparatus 6 is installed onto the exhaust pipe 4 side similar in case of the valve apparatus 6.</p> |
