Abstract
Description
図1は、第1実施形態の消音器2を適用した装置(スクリュ圧縮機)の一部を示す概略図である。消音器2は、流体の流れに重畳して音波が伝搬される流路に組み込まれる。本実施例では、流体である圧縮空気の流通により生じる音を消音するために、消音器2がスクリュ圧縮機本体4の吐出流路6に配置されている。
図6は、第2実施形態の消音器2を示す縦断面模式図である。本実施形態の消音器2は、導入減衰部10の端部に関する部分以外の構成は図2の第1実施形態と同様である。従って、図1に示した構成と同様の部分については同様の符号を付して説明を省略する。
図9は、第3実施形態の消音器2を示す縦断面模式図である。本実施形態の消音器2は、導入減衰部10の端部に関する部分以外の構成は図2の第1実施形態と同様である。従って、図1に示した構成と同様の部分については同様の符号を付して説明を省略する。
