Description
実施の形態1.
図1に示すEGRバルブは、バルブ開閉の回転駆動力を発生させるアクチュエータ部10と、アクチュエータ部10の駆動力をロッド(弁軸)32に伝達するギア部20と、高温の排ガスが流通する管(不図示)に介装され、バタフライ弁状のバルブ(弁体)37を開閉して排ガスの流通を制御するバルブ部30とからなる。
また、ロッド32にはバルブ37が固定されており、このバルブ37がロッド32と一体に回転して、ガス通路38に設けられたバルブシート39に当接してガスの流通を止める。
ガス通路38を流通するガス、及びバルブ37とバルブシート39の隙間から洩れ出るガスは、ロッド32の外周面に沿って軸方向上向きに軸洩れするが、プレート36がロッド32の外周面に圧入されているため、プレート36の内周面とロッド32の外周面に隙間がなく、この部分から軸洩れすることもない。
そこで、ブッシュ35の軸方向下側の端部外径をプレート36の外径より小さくなるように縮径して、縮径端部35aを形成する。これにより、ブッシュ35に対してプレート36が回転して当接面が磨耗したとしても、段差がなく均一に磨耗するようになるので、ブッシュ35とプレート36の磨耗部分が噛み込んだり引っ掛かったりしにくい構造になっている。
