Abstract
【解決手段】弁装置5は、ステー51により第1回転軸線71A及び第2回転軸線72Aを中心にそれぞれ回転移動可能に支持されたバタフライ52及び第1リンク部材53と、バタフライ52により第3回転軸線73Aを中心に回転移動可能に支持された第2リンク部材54と、バタフライ52を閉弁方向へ付勢するためのバネ55と、を備える。第1リンク部材53及び第2リンク部材54は、第4回転軸線74Aを中心に互いに回転移動可能に接続されている。そして、第2回転軸線72Aと第4回転軸線74Aとを結ぶ第1リンク線L1と、第3回転軸線73Aと第4回転軸線74Aとを結ぶ第2リンク線L2と、により形成される角度が、バタフライ52の閉弁状態で最も大きく形成される。
【選択図】図2
Description
図1に示すマフラ1は、車両に搭載された内燃機関(図示せず)から排出される排ガスの排気流路の一部を構成するものであり、筒状のシェル部材11の両端開口部が後蓋部材12と前蓋部材13とにより閉塞された筐体10を備えている。筐体10の内部は、第1セパレータ21と第2セパレータ22とにより、第1室31、第2室32及び第3室33の3室に区画されている。
(1)上記実施形態では、バタフライ52を閉弁方向へ付勢するための付勢手段として、バタフライ52及び第2リンク部材54を閉弁時の位置関係(角度)に近づける方向に付勢するバネ55を例示したが、これに限定されるものではない。例えば図6(A),(B)に示すように、バネ55を第4回転軸部材74に取り付け、第1リンク部材53及び第2リンク部材54を、閉弁時の位置関係(角度)に近づける方向に付勢するようにしてもよい。また、例えば図7(A),(B)に示すように、バネ55を第2回転軸部材72に取り付け、ステー51及び第1リンク部材53を、閉弁時の位置関係(角度)に近づける方向に付勢するようにしてもよい。
