Claims (1)
方向への移動量の増大に応じて開弁量を増大する
アイドル回転数制御用の吸入空気量制御弁要素と
、吸入空気量制御弁要素と同一軸線上に設けられ
前記第一の方向とは反対の第二の方向へ移動する
ことにより開弁し第二の方向への移動量の増大に
応じて開弁量を増大する排気ガス再循環流量制御
弁要素と、前記第一の方向と前記第二の方向とに
往復動移動し前記第一の方向への移動により前記
排気ガス再循環流量制御弁要素より離間して前記
吸入空気量制御弁要素にのみ係合し該吸入空気量
制御弁要素を開弁方向へ駆動し前記第二の方向へ
の移動により前記吸入空気量制御弁要素より離間
して前記排気ガス再循環流量制御弁要素にのみ係
合し該排気ガス再循環流量制御弁要素を開弁方向
へ駆動するアクチユエータとを有するアイドル制
御用吸入空気量制御兼排気ガス再循環制御弁。 An intake air amount control valve element for idle rotation speed control that opens by moving in a first direction and increases the opening amount as the amount of movement in the first direction increases, and an intake air amount control valve. Exhaust gas that is provided on the same axis as the element, opens a valve by moving in a second direction opposite to the first direction, and increases the amount of opening of the valve as the amount of movement in the second direction increases. a recirculation flow control valve element that reciprocates in the first direction and the second direction to move the intake air away from the exhaust gas recirculation flow control valve element by movement in the first direction; The intake air amount control valve element engages only with the intake air amount control valve element, drives the intake air amount control valve element in the valve opening direction, and moves away from the intake air amount control valve element by moving in the second direction, thereby controlling the exhaust gas recirculation flow rate. An actuator that engages only with a valve element and drives the exhaust gas recirculation flow rate control valve element in a valve opening direction.
