御するようにしたスロットルバルブの制御装置において
、前記負圧作動器の負圧室にスロットルバルブの所定開
度以下では大気圧側に、所定開度以上て負圧側となる負
圧ポートからオリフィスを備える逆止弁を介して負圧を
導入するとともに、該逆止弁と前記負圧ポート間の負圧
ラインから機関の所定の運転状態を検出して開閉制御す
る開閉弁を介してスロットルバルブ下流の負圧ポートに
連通ずる負圧ラインを分岐して設けるようにしたことを
特徴とする内燃機関のスロットルバルブ制御装置。In a throttle valve control device in which a throttle valve of a carburetor of an internal combustion engine is controlled by a negative pressure actuator, a negative pressure chamber of the negative pressure actuator has a predetermined pressure on the atmospheric pressure side when the opening of the throttle valve is below a predetermined opening. Negative pressure is introduced from a negative pressure port that becomes negative pressure side when the opening is higher than that, through a check valve having an orifice, and a predetermined operating state of the engine is controlled from a negative pressure line between the check valve and the negative pressure port. A throttle valve control device for an internal combustion engine, characterized in that a negative pressure line is branched and communicated with a negative pressure port downstream of a throttle valve via an on-off valve that detects and controls opening and closing.
