この考案は、オイルフィルタ、その他のフィルタ装置に利用される渦巻状フィ ルタエレメントに関する。 The present invention relates to a spiral filter element used in oil filters and other filter devices.

【従来の技術】[Prior Art]

自動車に搭載されたエンジンの潤滑オイルは、エンジンの作動時において常時 オイルフィルタを介して濾過され、オイルに含まれている異物が除去される。こ の異物は、燃焼時に発生する“すす”が大部分を占め、この“すす”がサブミク ロン単位でオイル中に混入、分散されると、これによって各摺動部の磨耗が促進 されたり、オイルの粘度が上昇してオイルポンプの吐出量が低下し、潤滑不足が 起こり摺動部のオイル切れを来したりする。 Lubricating oil for an engine mounted on an automobile is always filtered through an oil filter when the engine is operating, and foreign matter contained in the oil is removed. Most of this foreign material is "soot" generated during combustion. When this "soot" is mixed and dispersed in the oil in submicron units, this promotes wear of the sliding parts, The viscosity of the oil rises and the discharge rate of the oil pump decreases, causing insufficient lubrication and causing the sliding parts to run out of oil.

【0003】 内燃機関、特にディーゼル機関にあっては長時間運転されることが多いため、 オイルの汚れが激しく、エンジンの磨耗を防止すると同時にオイルの粘度などの 性状を維持するためには粒状物質や微粒子を多量に濾過する必要がある。このよ うな条件を満足するオイルの浄化用フィルタとして渦巻状フィルタエレメントが バイパス用に多用されている。この渦巻状フィルタエレメントは濾過材を渦巻状 に巻くことによってフィルタ体が構成されるようにしたものであり、例えば、特 公昭62−48522号公報には、濾過液体がフィルタ体の軸方向に沿って濾過 される方式として一定幅の複数の紙層を同時に巻取った紙巻き濾過エレメントが 例示されている。Since an internal combustion engine, especially a diesel engine, is often operated for a long time, the oil is heavily contaminated, and in order to prevent engine wear and at the same time maintain properties such as oil viscosity, particulate matter It is necessary to filter a large amount of fine particles. A spiral filter element is often used for bypass as a filter for purifying oil that satisfies these conditions. This spiral filter element is one in which a filter body is constructed by spirally winding a filter medium. For example, in Japanese Patent Publication No. 62-48522, a filter liquid is introduced along the axial direction of the filter body. As a method of filtering by means of a filter, a paper-wrapping filter element in which a plurality of paper layers having a constant width are simultaneously wound is illustrated.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら,従来の渦巻状フィルタエレメントでは、濾過液体はフィルタ体 の軸方向に沿って濾過される方式となっているため、ケースとフィルタ体の間か ら濾過液体が漏洩しないように渦巻状にしたフィルタ体をエレメントケースの中 に密着して挿入しており、ケース内へのフィルタ体の挿入に手間を要するととも に、フィルタエレメントの使用中に巻取った巻き紙が変形を起こして巻層全体を 均一に利用できない問題が生じていた。 However, in the conventional spiral filter element, since the filtered liquid is filtered along the axial direction of the filter body, the spiral wound filter element has a spiral shape so that the filtered liquid does not leak between the case and the filter body. The filter body is inserted closely into the element case, and it takes time and effort to insert the filter body into the case, and the wrapping paper rolled up during use of the filter element deforms to form a wrapping layer. There was a problem that the whole system could not be used uniformly.

【0005】 この考案は以上の問題を解決するものであって、その目的は、渦巻状フィルタ エレメントの製作を容易にするとともに、使用中のフィルタエレメントが変形を 起こさず、濾過材の巻層全体を有効に活用して安定した濾過が確保される渦巻状 フィルタエレメントを提供することにある。The present invention solves the above problems, and an object thereof is to facilitate the manufacture of a spiral filter element and to prevent the filter element in use from being deformed so that the entire wound layer of the filter medium can be formed. It is to provide a spiral filter element in which stable filtration is ensured by effectively utilizing the above.

【0006】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

上記課題を達成するため,この考案は,オイルが流通可能なシート状の第一ス ペーサ材を濾過材により包囲して三層の濾過部材を形成し、この濾過部材の端部 に前記第一スペーサ材と連通する孔開内筒を挿入し、この孔開内筒の外周に前記 濾過部材を同軸状に巻き回すとともに、該濾過材間には外部からオイルが流通さ れる第二スペーサ材を介装し、これら第一および第二スペーサ材の軸方向端部を エンドプレートによって密閉状に覆ってなることを特徴とする。 In order to achieve the above-mentioned object, the present invention forms a three-layer filter member by surrounding a sheet-shaped first spacer member through which an oil can flow with a filter member, and the first member is provided at the end of the filter member. Insert a perforated inner cylinder that communicates with the spacer material, wind the filter member coaxially around the perimeter of the perforated inner cylinder, and install a second spacer material through which oil flows from the outside between the filter materials. It is characterized in that it is interposed and the axial end portions of these first and second spacer members are covered in an airtight manner by end plates.

【0007】[0007]

【作用】[Action]

濾過部材が第二スペーサ材を内側にして孔開内筒に渦巻状に巻き付けて上下が エンドプレートで接着接合されており、濾過は渦巻状の濾過材に沿って行われる のでエレメントケースを必要とせず、ケースとエレメントの漏洩を考慮する必要 がなく、また第二スペーサ材で濾過部材が確実に保持されているのでフィルタエ レメントが変形を起こさず、濾過材の巻層全体を有効に利用して安定した濾過が 確保される。 The filtering member is wound spirally around the bored inner cylinder with the second spacer material inside, and the upper and lower parts are adhesively joined by end plates.Since filtration is performed along the spiral filtering material, an element case is not required. In addition, it is not necessary to consider leakage of the case and the element, and since the filter member is securely held by the second spacer material, the filter element does not deform and the entire wound layer of filter material is effectively used. Stable filtration is ensured.
