Description
本発明は、液体や気体などの流体の濾過のために用いられるフィルタ構成に関する。本発明は、特に、直線的な流れを有するフィルタカートリッジと、安全フィルタと、このようなフィルタを備える組立体と、予備クリーナと、フィルタカートリッジの使用方法および組立体に関する。
一般に、ここに記載される本発明の原理は、点検整備可能なフィルタカートリッジにとり望ましい特徴点となる。このフィルタカートリッジは、さまざまな構造を備えることで、代表的には空気濾過のための主要フィルタカートリッジとして使用することができる。ここで、この文脈で「点検整備可能」の用語は、フィルタカートリッジが一区切りの使用期間経過後に、エアクリーナから取り除かれるかまたは取り替えられるフィルタカートリッジであることを意味する。また、「主要」の用語は、ほこりまたは他の汚染物質の大部分がエアクリーナ中の濾材を通り抜けるときに、捕捉されるフィルタカートリッジであることを意味する。
ここに記述される技術は、流体の濾過装置に概ね適用することができる。一般に、本技術が適用される技術分野としては、液体濾過装置と気体濾過装置の2つのタイプがある。図示された実施形態は、特にエアクリーナ(すなわち、一種の気体濾過装置)であり、この特徴はこの文脈で記述されることとなる。液体濾過装置または他の気体濾過装置に関する原理と技術の適用可能性については、後述の説明から明らかになるであろう。
図2を参照すると、フィルタカートリッジ22は直線的な流れが可能となるように構成されている。ここで、「直線的な流れ」の用語の意味は、濾過を行うためにフィルタカートリッジ22に流入する流体は入口端部または表面23から第1の方向でフィルタカートリッジ22の濾材積層体26中に流入し、同じ方向に流れて反対の出口端部か表面24から流出することを意味する。上記の「直線的な流れ」の特徴は、ひだをつけられた濾材から形成された筒状のフィルタ表面に向けて空気が流入され、約90回転された後に濾過後の空気を(例えば開口から)外部に流出させるように構成された流れシステムであって、例えば1989年3月9日に公開されたPCT公表第WO89/01818号のシステムとは特に異なる。
さまざまな長円形として、例えば楕円形と競馬場の走路形状が挙げられる。一般に、長円形は対向する2つの曲線部と、これらの曲線部の端部から延びる直線部とを備えるとして特徴付けることができる。すなわち、「走路形状」は、一般に2つの平行な直線部と、これらから延びる2つの曲線部とを備える。楕円形は、平行な直線部にわずかな反りが通常設けられ、左右対称形状となる曲線部を備える。
次に、図11〜図14を参照すると使用可能な安全フィルタ20の実施形態が図示されている。望ましいシステムでは安全フィルタ20は主要なフィルタカートリッジ22が故障した場合に、主要なフィルタカートリッジ22を通過するゴミから下流のコンポーネントを保護するために主要なフィルタカートリッジ22の下流にゴミを含む空気が流れないようにエアクリーナ1を構成すると良い。加えて、安全フィルタ20は図4に図示したように清浄大気領域32に位置することから、エアクリーナ1を点検している間にエンジンを保護する一助となる。
図2〜図4において、望ましい予備クリーナ部分8が図示されている。ここで、多くの異なる従来構成の予備クリーナを主要フィルタエレメント22の上流に配置することで、図示される特定の予備クリーナ8を効果的に使用することができる。
一般的に、上記のような直線的な流れ構造を備えたフィルタエレメントをシールするための方法が提供されることとなる。一般的に望ましい方法によれば、図示されるようにカバーと一次エアクリーナ部分の夫々のフランジを対向させるように位置決めし、シール(エレメントに設けられた)に対して係合させ、軸方向にシールを圧縮することでシール状態に維持される。
