Description

【発明の詳細な説明】 フィルタ 本発明は、請求項１の上位概念に記載の形式のフィルタに関する。このような 形式のフィルタは、例えば内燃機関のオイル循環路で使用するものとして公知で ある。金属製の支持網と、金属内部管及び金属端部ディスクを備えたプラスチッ ク製の濾過網とから成るこのような形式のフィルタを、今日の内燃機関に挿入し ようとする際には、フィルタが種々異なる材料から構成されているということに 欠点がある。このことは特に後からのフィルタの処理という観点で問題をひき起 こす。 フィルタ全体を金属で製造することは可能ではある。しかしこのことは製造コ ストがかかり、ひいてはフィルタを高価なものとする。さらにこれによりフィル タの全重量が増大し、このことは内燃機関の重量状態という観点でも不都合であ る。 そこで本発明の課題は、冒頭で述べた形式のフィルタを改良して、簡単で安価 であって、さらに耐用期間の終了時には僅かな手間で処理できるようなフィルタ を提供することにある。 この課題を解決するために本発明の構成では、フィルタが、ほぼ直角状の少な くとも１つのフィルタ媒体 と、ほぼ直角状の少なくとも１つの支持媒体とを有しており、該支持媒体が支持 手段として前記フィルタ媒体に取り付けられていて、この結合された媒体が星形 に屈曲されていて、その互いに接触する両端部がシールされて結合されており、 フィルタの端面が、シールするカバーを有しているようにした。ほぼ直角状のフ ィルタ媒体を使用することにより、製造時に例えば、エンドレスの巻き体からこ のフィルタ媒体を繰り出し、所定の区分ごとに射出成形型に導入し、これにより 支持媒体を同様にほぼ直角にフィルタ媒体上に射出成形することができる。この 場合の利点は、射出成形型の構成が簡単であることにある。支持媒体の射出成形 が、星形に屈曲したあと初めて行われるなら、極めてコストのかかる射出成形型 が必要である。 本発明による別の構成では、フィルタ媒体が、紙又はフリース又は濾過網から 成っている。この場合、分離限界に応じて、適当なフィルタ媒体の選択を特に簡 単に行うことができる。 さらに有利には、濾過網が金属又はプラスチックから形成されている。ここで 挙げた材料は、純粋な品質の材料構成という要求を満たすために、支持媒体若し くはカバーのために使用される材料に適宜合わせられる。 本発明の別の有利な構成は、カバーが、金属又はプラスチック又は紙から成っ ていることにある。このカ バーの材料選択は、濾過材及び支持媒体の材料と合わせて適宜に行うことができ る。 支持媒体がフィルムヒンジを有していて、このフィルムヒンジが星形軸線に関 して凹方向の屈曲若しくは凸方向の屈曲を交互に可能にするならばさらに有利で ある。ヒンジをこのように交互に配置することにより、射出成形装置において前 製造された扁平なフィルタを星形に屈曲することが初めて可能になる。というの もフィルムヒンジの材料狭隘部において屈曲が行われるからである。 本発明の別の有利な構成では、支持媒体がフィルムヒンジの領域、特に、凸方 向屈曲を可能にするフィルムヒンジの領域で、星形屈曲の角度を規定するアング ル状の切欠を有している。このような形式の斜角部は、均一なフィルタ本体の外 観を実現する。何故ならば、このような多層構造体は、さもないと不均一に屈曲 してしまう傾向があり、このことはフィルタの規定されない輪郭を生ぜしめるか らである。この場合の別の利点は、例えば、互いに接触する端部を所定のように シールできることにある。 本発明の別の有利な構成では、互いに接触する端部が接着されているか又は溶 接されている。このことは確実なシール結合を可能にし、その結果、使用におい て確実なフィルタを提供することになる。さらに、カバーがフィルタと支持媒体 とに溶接又は接着又はスナ ップ結合されていると有利である。金属の組み合わせに応じて、この結合は安価 で確実なフィルタの形成を保証する。 さらに有利には、少なくとも１つのカバーがフィルタバイパス弁を有している 。このバイパス弁は、濾過部材が塞がれてしまった場合に、内燃機関の内側でオ イル流が途切れないようにするために働く。 本発明の別の有利な構成のさらなる特徴は、請求項の他に、明細書と図面から も明らかである。この場合、個々の特徴はそれぞれ、それ自体でも、本発明の構 成における請求項２以下の複数の構成の組み合わせでもよく、別の分野で実用さ れても、ここで請求した保護により、保護されるべき構成が与えられる。 次に図面につき本発明の実施例を詳しく説明する。 第１図は、星形に屈曲されたフィルタの断面図であって、 第２図は、第１図の細部Ｙを示した図であって、 第３図は、支持媒体の側方図であって、 第４図は、第３図の細部Ｘを示した図であって、 第５図は、屈曲されていないフィルタエレメントの平面図であって、 第６図は、２つの濾過星形挿入体を有したフィルタケーシングを示す断面図で ある。 第１図には、星形に屈曲されたフィルタが断面図で示されている。細部Ｙが拡 大されて示されていること からわかるように、このフィルタの構成は主として、直角状のフィルタ媒体２と 支持手段３とから成っている。第２図からわかるように、この特別な構成では、 フィルタ手段２は星形軸線に関して外方に取り付けられているが、支持手段３の 内側に取り付けることも考えられる。支持手段３は、第５図に示したように例え ば、長手方向及び横方向に配置されたリブを有していて、これらのリブがフィル タの固有安定性を高めている。支持手段３は、特に、星形軸線に関して凸方向屈 曲を可能にするフィルムヒンジ４の領域で、規定された屈曲を可能にするアング ル状の切欠を有している。第３図により、フィルムヒンジ４が星形屈曲を可能に するために、一方のフィルムヒンジが星形軸線に関して凸方向屈曲６を可能にし 、これに続くフィルムヒンジ４が、凹方向屈曲７を可能にするように交互に形成 されていることがわかる。第４図には第３図の細部Ｘが拡大されて示されている 。ここでは、異なるフィルムヒンジ４がどのように交互に配置されているかとい うことが示されている。凸方向屈曲６を行うために必要な、支持媒体３のアング ル状の切欠は８は、第４図では具体的な実施例として、屈曲されていない平らに 伸ばされた支持媒体３に対して６０°の角度を有して示されている。例えば射出 成形過程で、扁平に設計されたほぼ直角状のフィルタ媒体２上に射出成形された 支持媒体３が第５図に示されている。ここでは例えば ポリエステル網が、この構成では前状態の巻き体から出て、射出成形型に導入さ れている。フィルタ媒体２は、射出成形行程の前又は後で巻き体から分離される 。このような射出成形過程によって、射出成形過程の直後にほぼ直角でかつ一貫 して扁平な結合フィルタが得られる。フィルタの長手方向で交互に配置されたフ ィルムヒンジ４によって、フィルタを例えば星形に屈曲することが可能である。 第１図に示したように、第５図に示した両端部９は、屈曲過程後に接着されるか 溶接される。フィルタの製造仕上げの際に、その端面には、有利にはフィルタ媒 体２及び／又は支持材料３と同じ材料から成るいわゆるカバー５が取り付けられ る。 実施例では、オイルを濾過するための装置が第６図に示されている。この装置 はケーシング１０とケーシングカバー１１とを有していて、このケーシングカバ ー１１は、フィルタ交換のために閉鎖部材２２を介して組外し・組み付け可能で あって、ばね１６によってフィルタ挿入体１ａ，１ｂをケーシングに対して緊定 し、シール部材２０を介してケーシング１０をシールする。さらにこの装置は入 口１３と出口１４とを有している。第６図に示した実施例は２つのフィルタ１ａ ，１ｂを有していて、これらのフィルタは異なる分離限界を有している。第１の フィルタ１ａは比較的粗いフィルタ媒体を有しており、そのため比較的大きな粒 子を通過させる。この第１のフィルタ１ａは、一方のカバー５においてフィルタ バイパス弁１２を有していて、この弁は主として弁ディスク１７と弁ばね１８と から成っている。微細なフィルタ媒体２を有した、ケーシング１０内に位置する 第２のフィルタ１ｂに対して、第１のフィルタ１ａはカバー５と、そのカバー内 に組み込まれた連結弁１５とによって分離されている。同様に弁ディスク１７と 弁ばね１８とを有した連結弁１５は、第１のフィルタを、例えば０．５バールの 運転過圧を越えると接続し、これに対し、第１のフィルタ内に位置するバイパス 弁を臨界運転状態で初めて接続し、乾式運転を防止する。純オイル側はこの装置 では、シール部材１９とセンタリング・スナップ・シール結合部とによって粗オ イル側から分離されている。第１のフィルタからの分離限界は、約６０μｍ〜６ ５μｍの範囲に位置している。第２のフィルタの分離限界は、約４０μｍの範囲 に位置している。選択的な構成では、ケーシング１０にフィルタ挿入体を１つだ け挿入することも可能である。DETAILED DESCRIPTION OF THE INVENTION                               filter   The invention relates to a filter of the type defined in the preamble of claim 1. like this Filters of the type are known, for example, for use in oil circuits of internal combustion engines. is there.
