Description
吸入空気が通過するランナーの長さを可変させるため、吸気マニホールドアセンブリーには、バルブ軸によりバルブが回動可能に取り付けられ、前記バルブ軸の取付けには多数のリテーナーおよびボルトが使用される。
このように、バルブ軸を固定するために使用するリテーナーおよびボルトは、バルブを安定に支持しなければならなく、その装着状態を堅固に維持しなければならない。
可変吸気システムのバルブ軸が軸支される軸支持部が中央部に設けられ、固定ボルトのシャンク部が挿入されるフォーク部が中央部の両側端にそれぞれ設けられ、フォーク部との間に、固定ボルトの頭部を収容する空間を有するように、フォーク部から離隔して遮断部が形成され、遮断部には、固定ボルトを締結するための工具が通過する工具挿入孔が形成され、
軸支持部には、固定ボルトが締結されるとき、固定ボルトが螺旋運動する方向の反対側にバルブ軸が挿入されるようにする軸挿入口が形成され、軸挿入口の大きさはバルブ軸の直径より小さく形成されて、軸支持部の弾性変形によりバルブ軸が軸支持部に挿入されることを特徴とする。
図1は本発明が適用された可変吸気システムの内部構造を示すもので、吸気マニホールドアセンブリー1の中央に、複数のフラップが備えられたバルブ3がバルブ軸5により回動可能に固定されており、バルブ3の両側には、複数の燃焼室に連結されるランナー7が配設されている。
したがって、本発明のリテーナー9は、多少の変形が可能なプラスチック材質からなることが好ましい。
