- それぞれの中心部に同心状に円形孔が形成され平行に配設された一対の円板間に、それぞれ2つの屈曲部を有し全体としてZ形状に形成され、前記両円板の内周縁側における端部が前記両円板の中心線に対し0°の角度に形成された複数の吸音スプリッタを、前記両円板間の外方から内方に空気が吸込まれるように両円板の円周方向に間隔を隔て、かつ、隣位の一対の吸音スプリッタが並行に位置するように配設され、過給機の空気吸込口に取付けられ、空気吸込口から外側に放射される過給機騒音の消音を行なうための過給機用サイレンサにおいて、
前記吸音スプリッタが、ポリエステル系繊維を焼結により圧縮加工して形成されていることを特徴とする過給機用サイレンサ。 - 隣位の一対の前記吸音スプリッタ間の空気通路の間隔は、前記両円板の外方から内方に向けて漸減するように形成されていることを特徴とする請求項1に記載の過給機用サイレンサ。
- 前記各吸音スプリッタの各屈曲部の凸側は円弧面に形成されていることを特徴とする請求項1または請求項2に記載の過給機用サイレンサ。
- 過給機の空気吸込口に取付けられ、空気吸込口から外側に放射される過給機騒音の消音を行なうための過給機用サイレンサにおいて、
それぞれの中心部に同心状に円形孔が形成され平行に連結された一対の円板間に、ポリエステル系繊維を焼結により圧縮加工し、それぞれ前記両円板と同心状の円形孔を有するドーナツ形状に形成された複数の吸音スプリッタが、前記両円板と平行かつ等間隔に配設されていることを特徴とする過給機用サイレンサ。 - 前記各吸音スプリッタが、それぞれ少なくとも円周方向において2つ以上に分割されているとともに、平行に配設され分割された各吸音スプリッタが、それぞれ周方向の端部において連結されているとともに、連結されている吸音スプリッタが容易に組込みおよび取外しできることを特徴とする請求項4に記載の過給機用サイレンサ。
- 前記各吸音スプリッタの表面が、ポリエステル系不織布により被覆されていることを特徴とする請求項1乃至請求項5のいずれか1項に記載の過給機用サイレンサ。
