Abstract
Description
[1.構成]
図1に示すマフラ100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の両端開口部が前端板12と後端板13とにより閉塞された筐体14を備える。筐体14の内部は、仕切板101により上流室14a及び下流室14bに区画されている。上流室14aは、前端板12と仕切板101との間に形成され、下流室14bは、後端板13と仕切板101との間に形成されている。
次に、弁装置10の作用について説明する。内燃機関から筐体14に流入した排ガスは、図1において矢印で示すように、複数の貫通孔15aを介して上流室14aに導入される。そして、上流室14aに導入された排ガスは、仕切板101に取り付けられている弁装置10を介してアウトレットパイプ16に流入し、図示しないテールパイプを介してマフラ100の外部に排出される。
以上詳述した本実施形態によれば、以下の効果が得られる。
(1a)本実施形態の弁装置10では、貫通孔101bを覆うように仕切板101に固定されたケース102が、下流流路と連通しかつ弁体103を収容する収容空間102aを有している。そして、弁体103は、このように設けられた収容空間102aの内側から流入孔102bを閉塞する。つまり、ケース102は、弁体103を収容するとともに、弁体103の弁座部102cを形成している。したがって、本実施形態によれば、弁装置10を構成するための部品点数を少なくすることが可能となる。
以上のような効果について、図5に示す比較例のマフラ200と対比しつつ説明する。比較例のマフラ200は、筐体24と、複数の貫通孔25aが設けられたインレットパイプ25と、アウトレットパイプ26と、弁装置20と、バイパス用パイプ27と、を備える。筐体24、インレットパイプ25、アウトレットパイプ26及び弁装置20は、実施形態の筐体14、インレットパイプ15、アウトレットパイプ16及び弁装置10と同様の機能を有する。
前端板209は、バルブケース208の上流側開口を塞ぐようにバルブケース208に固定されている。前端板209は、バルブケース208とともに、弁体203及びステー210を収容する収容空間208aを有している。前端板209は、収容空間208aへ排ガスを流入させる流入孔209aを有している。
以上、本開示の実施形態について説明したが、本開示は、上記実施形態に限定されることなく、種々の形態を採り得ることは言うまでもない。
