Description
前記流体圧機器に接続され、該流体圧機器から圧力流体が導入される本体部と、
異なる開口面積を有する複数の積層されたフィルタからなり、前記本体部に保持される吸音部と、
前記本体部から前記吸音部を通じて外部へと排気される圧力流体の流量を、前記流体圧機器から離間する方向に向かって徐々に増大させる流量調整手段と、
を備え、
前記流量調整手段は、前記吸音部の内部に設けられて前記本体部と連通した筒体からなり、前記筒体の外壁には前記流体圧機器から離間する方向に向かって徐々に数量が増大する複数の孔部が形成されると共に、前記フィルタの開口面積は、前記本体部側となる上流側から前記吸音部の外部側となる下流側に向かって順に小さくなるように設定されることを特徴とする。
前記連通路に形成される弁座に着座する弁体と、
前記弁体を前記弁座側に向かって押圧するスプリングと、
を備えるとよい。これにより、サイレンサの内部で圧力流体の圧力が上昇した際に、前記圧力によって弁体がスプリングの弾発力に抗して弁座より離間し、前記弁体と弁座との間から圧力流体が流通する。その際に、前記圧力流体の通過音が発生し、前記通過音を介して作業者が検出機構によるサイレンサの異常を容易に確認することが可能となる。
