Claims (1)
- 内燃機関に備えられ、排気ガスを吸気系のスロットル弁よりも下流側に還流させる排気ガス還流装置であって、
還流させる排気ガスの流量を調整する排気ガス還流弁と、この排気ガス還流弁を収納するとともに排気ガス還流弁より下流側に吸気系の吸気集合部に連通する通路を有する弁ケースと、この弁ケースに一体的に設けられる逆止弁とを備え、
前記弁ケース内の通路が内燃機関の一のシリンダから該シリンダに隣接するシリンダに向かう方向に延びる吸気系の吸気集合部の長手方向と交差する方向に延び、
前記通路が吸気系の吸気集合部の長手方向に延びる中心軸と略同一平面上にあるか、又は吸気系の吸気集合部の長手方向に延びる中心軸とオフセットするよう位置するとともに、
前記逆止弁が、シリンダから遠い側の端部を弁ケースに枢着して固定端としているとともにシリンダに近い側の端部を自由端としていることを特徴とする排気ガス還流装置。
