Description
図1は、本発明の一実施形態であるリターンフィルタ1の概略を示す図である。リターンフィルタ1は、図示しない作業機械(例えば、油圧装置)に設置される作動油タンク(図示せず)内に設けられる濾過装置であり、油に含まれる塵埃等を除去するものである。なお、リターンフィルタ1は濾過装置の一例であり、本発明の濾過装置はリターンフィルタに限られない。また、本実施の形態では、リターンフィルタ1は油を濾過するが、本発明の濾過装置は油以外の液体(水等)を濾過することもできる。
第1の実施の形態では、リリーフバルブ61全体を多孔質材料により形成することで、リリーフバルブ61全体を用いて流入空間S3の上部に溜まった空気を排出したが、流入空間S3の上部に溜まった空気を排出する形態はこれに限られない。
第2の実施の形態では、リリーフバルブ64に空気抜き部材65を設けたが、空気抜き部材65が貫通孔64aに嵌入されるのであれば、空気抜き部材65を設ける位置はこれに限られない。
