Claims (1)
積を制御することにより排気ガス圧力を、制御する内燃
機関の排気ガス圧力制御弁に於て、前記排気通路の通路
壁に当接することにより定められる最大閉弁位置にある
時に前記排気通路の実効通路断面積を所定の最小′値に
設定するよう構成されていることを特徴とする排気ガス
圧力制御弁。In an exhaust gas pressure control valve of an internal combustion engine that is provided in the middle of an exhaust passage and controls the exhaust gas pressure by controlling the effective passage cross-sectional area of the non-passage, the exhaust gas pressure control valve contacts the passage wall of the exhaust passage. An exhaust gas pressure control valve characterized in that the exhaust gas pressure control valve is configured to set the effective passage cross-sectional area of the exhaust passage to a predetermined minimum value when the valve is at a maximum closed position determined by the above.
