　上記課題を解決するために、本発明に係る油水分離装置は、例えば、中心軸が鉛直方向と略平行に設けられる略有底筒状のケース本体と、前記ケース本体の開口部を覆う蓋であって、濾過前の油を前記ケース本体の内部に導く流入部と、濾過後の油を前記ケース本体から外部に流出させる流出部と、を有する蓋と、前記ケース本体の高さより低く、前記ケース本体の内部に、中心軸が鉛直方向と略平行に設けられる略筒状の濾材を有し、下端部が覆われ、中空部が前記流出部と連通するように上端部が前記蓋に液密に設けられるフィルタエレメントと、前記ケース本体の高さより低く、前記フィルタエレメントの外周面を覆うように前記ケース本体の内部に設けられる略筒状の内部ケースと、を備え、前記流入部は、中心軸が前記ケース本体の中心軸と直交するように設けられ、前記流出部は、中心軸が前記ケース本体の中心軸に沿って設けられ、前記ケース本体の内部には、前記フィルタエレメント及び前記内部ケースの鉛直方向下方に、貯留部となる空間が形成され、前記濾過前の油は、前記流入部から前記内部ケースと前記ケース本体との間に流入して下方に移動し、前記濾過前の油に含まれる水分及びスラッジは、前記貯留部に沈殿することを特徴とする。 In order to solve the above problems, an oil-water separator according to the present invention includes, for example, a substantially bottomed cylindrical case body whose central axis is provided substantially parallel to the vertical direction, and a lid that covers the opening of the case body. A lid having an inflow portion that guides oil before filtration to the inside of the case body, and an outflow portion that causes oil after filtration to flow out of the case body to the outside, lower than the height of the case body, The case main body has a substantially cylindrical filter medium whose central axis is provided substantially parallel to the vertical direction, the lower end is covered, and the upper end is liquid to the lid so that the hollow portion communicates with the outflow portion. A filter element that is densely provided, and a substantially cylindrical inner case that is lower than the height of the case body and that is provided inside the case body so as to cover the outer peripheral surface of the filter element. The central axis is the case book The outflow portion is provided so that the center axis is provided along the center axis of the case main body, and the filter body and the inner case are vertically below the case main body. In addition, a space serving as a storage portion is formed, and the oil before filtration flows between the inner case and the case main body from the inflow portion and moves downward, and moisture contained in the oil before filtration. And sludge settles in the storage part.
　本発明によれば、濾過前の油は、中心軸がケース本体の中心軸と直交するように蓋に形成された流入部から内部ケースとケース本体との間に流入し、重力により下方に移動する。そして、濾過前の油に含まれる水分及びスラッジは、油より重いため、重力により、フィルタエレメント及び内部ケースの鉛直方向下方に位置する貯留部に沈殿する。これにより、油に含まれる水分及びスラッジを沈殿させて分離することができる。 According to the present invention, the oil before filtration flows between the inner case and the case body from the inflow portion formed on the lid so that the center axis is orthogonal to the center axis of the case body, and moves downward by gravity. To do. And since the water | moisture content and sludge contained in the oil before filtration are heavier than oil, it settles to the storage part located in the vertical direction downward direction of a filter element and an inner case with gravity. Thereby, the moisture and sludge contained in the oil can be precipitated and separated.
　ここで、前記流入部は、前記蓋の周縁近傍に設けられ、前記流入部の中心軸は、前記蓋の前記流入部が設けられる位置における法線方向と略一致してもよい。したがって、ケース本体と内部ケースとの間の空間に流入した濾過前の油は、ケース本体の内周面及び内部ケースの外周面に沿って旋回しながら、重力により鉛直下向き（－ｚ方向）に移動する（サイクロン）。これにより、油に含まれる水分及びスラッジを遠心力と重力とにより分離することができる。 Here, the inflow portion may be provided in the vicinity of the periphery of the lid, and a central axis of the inflow portion may substantially coincide with a normal direction at a position where the inflow portion of the lid is provided. Therefore, the unfiltered oil that has flowed into the space between the case body and the inner case swivels along the inner peripheral surface of the case main body and the outer peripheral surface of the inner case, and moves vertically downward (−z direction) due to gravity. Move (cyclone). Thereby, the water | moisture content and sludge contained in oil can be isolate | separated by centrifugal force and gravity.

And a second filter medium. Thereby, the water | moisture content which did not precipitate in the storage part can be collected.
　ここで、略円筒形状の第２のフィルタエレメントを備え、前記内部ケースは、中空部を有する円筒部が下端面に形成され、前記第２のフィルタエレメントは、中空部が前記円筒部の中空部と連通するように、上端部が前記円筒部に液密に設けられ、前記フィルタエレメントと前記第２のフィルタエレメントとは、前記ケース本体の内部に鉛直方向に並べて設けられてもよい。これにより、セジメンタの機能であるスラッジ分離機能と、燃料フィルタの油水分離機能とを一体とすることができる。 Here, the substantially cylindrical second filter element is provided, the inner case has a hollow cylindrical portion formed on the lower end surface, and the second filter element has a hollow portion of the hollow cylindrical portion. The upper end portion may be liquid-tightly provided in the cylindrical portion so as to communicate with the first and second filter elements, and the filter element and the second filter element may be provided side by side in a vertical direction inside the case body. Thereby, the sludge separation function that is the function of the cementer and the oil / water separation function of the fuel filter can be integrated.

＜第１の実施の形態＞ Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<First Embodiment>

FIG. 2 is a plan view of the cementer 1. FIG. 3 is a cross-sectional view of an essential part showing an outline of the cementer 1. The cementer 1 removes moisture and sludge contained in a liquid such as fuel. In FIG. 3, hatching indicating a cross section is partially omitted for explanation.
　セジメンタ１は、主として、ケース本体１０と、ヘッド２０と、フィルタエレメント３０と、内部ケース４０と、を有する。 The cementer 1 mainly includes a case main body 10, a head 20, a filter element 30, and an inner case 40.
　ケース本体１０は、例えば透明な樹脂を用いて形成された有底筒状の部材である。本実施の形態では、ケース本体１０は略有底円筒形状である。ケース本体１０は、中心軸Ａ１が鉛直方向（ｚ方向）と略平行に設けられる。 The case body 10 is a bottomed cylindrical member formed using, for example, a transparent resin. In the present embodiment, the case body 10 has a substantially bottomed cylindrical shape. The case body 10 is provided with a central axis A1 substantially parallel to the vertical direction (z direction).
　ケース本体１０の底面（－ｚ側の面）には、ドレンプラグ１１が設けられる。ドレンプラグ１１を抜くと、ケース本体１０に沈殿した水分及びスラッジ（後に詳述）が外部に排出される。ケース本体１０の内部には、フロート１２が封入される。フロート１２は、比重が水より小さく、油より大きい材料で、水面に浮かぶように形成される。 A drain plug 11 is provided on the bottom surface (the surface on the −z side) of the case body 10. When the drain plug 11 is pulled out, moisture and sludge (described later in detail) precipitated in the case body 10 are discharged to the outside. A float 12 is enclosed inside the case body 10. The float 12 is made of a material having a specific gravity smaller than that of water and larger than that of oil, and floats on the water surface.
　また、ケース本体１０の上側（＋ｚ側）には、ヘッド２０が取り付けられる。ヘッド２０は、ケース本体の開口部を覆う部材であり、金属又は樹脂で形成される。ヘッド２０は、全体として略円板形状であり、その中心はケース本体１０の中心軸Ａ１と同一である。 Also, the head 20 is attached to the upper side (+ z side) of the case body 10. The head 20 is a member that covers the opening of the case body, and is formed of metal or resin. The head 20 has a substantially disc shape as a whole, and the center thereof is the same as the central axis A <b> 1 of the case body 10.
　ヘッド２０には、濾過される前の燃料Ｆをセジメンタ１に導く流入路２０ａ（図２参照）と、セジメンタ１で濾過された後の燃料Ｆをセジメンタ１外部に排出する流出路２０ｂ（図３参照）と、が形成される。 The head 20 has an inflow path 20a (see FIG. 2) for guiding the fuel F before being filtered to the sedimentor 1, and an outflow path 20b (FIG. 3) for discharging the fuel F after being filtered by the segmenter 1 to the outside of the sedimentor 1. Reference) is formed.
　流入路２０ａは、筒状であり、流入路２０ａの中心軸Ａ２は、ケース本体１０の中心軸Ａ１と直交する方向であるｘ方向に沿って設けられる。流入路２０ａは、ヘッド２０の周縁近傍に形成されるため、中心軸Ａ２は、ヘッド２０の流入路２０ａが設けられる位置Ｂにおける法線方向と略一致する。これにより、流入路２０ａからケース本体１０の内部に導かれた燃料Ｆは、ケース本体１０の内周面に沿って流れる。 The inflow path 20a is cylindrical, and the central axis A2 of the inflow path 20a is provided along the x direction, which is a direction orthogonal to the central axis A1 of the case body 10. Since the inflow path 20a is formed near the periphery of the head 20, the central axis A2 substantially coincides with the normal direction at the position B where the inflow path 20a of the head 20 is provided. As a result, the fuel F guided from the inflow path 20 a to the inside of the case body 10 flows along the inner peripheral surface of the case body 10.
　流出路２０ｂは、中心軸がケース本体１０の中心軸Ａ１と同一である。すなわち、流出路２０ｂは、ヘッド２０の中央に設けられる。ただし、流出路２０ｂの中心軸は、中心軸Ａ１に沿って設けられていればよく、中心軸Ａ１と同一でなくてもよい。 The center axis of the outflow passage 20b is the same as the center axis A1 of the case body 10. That is, the outflow path 20 b is provided in the center of the head 20. However, the central axis of the outflow channel 20b only needs to be provided along the central axis A1, and may not be the same as the central axis A1.
　ヘッド２０の外周面には、雄ねじ２０ｃが形成される。雄ねじ２０ｃは、リング部材２１の内周面に形成された雌ねじ２１ａと螺合される。ケース本体１０とヘッド２０との間には、ガスケット２２が設けられる。リング部材２１の雌ねじ２１ａを雄ねじ２０ｃに締め付けることで、セジメンタ１内部が密封され、ケース本体１０とヘッド２０との間から液体が漏れないようにシールされる。 A male screw 20 c is formed on the outer peripheral surface of the head 20. The male screw 20 c is screwed with a female screw 21 a formed on the inner peripheral surface of the ring member 21. A gasket 22 is provided between the case body 10 and the head 20. By tightening the female screw 21a of the ring member 21 to the male screw 20c, the inside of the cementer 1 is sealed, and sealing is performed so that liquid does not leak from between the case body 10 and the head 20.
　フィルタエレメント３０は、主として、濾材３１と、内筒３２と、を有する。濾材３１は、ケース本体１０に導かれた燃料Ｆを濾過する部材であり、板状の材料をひだ折りして（プリーツ状にして）略円筒形状にすることにより形成される。濾材３１は、燃料Ｆ中の水分を分離し、ダストを捕獲する。セジメンタ１の使用状態において、濾材３１の中心軸は、鉛直方向に略沿って設けられる。ここでは、濾材３１の中心軸は、ケース本体１０の中心軸Ａ１と同一である。 The filter element 30 mainly includes a filter medium 31 and an inner cylinder 32. The filter medium 31 is a member that filters the fuel F guided to the case body 10 and is formed by folding a plate-like material (pleat-shaped) into a substantially cylindrical shape. The filter medium 31 separates moisture in the fuel F and captures dust. In the usage state of the cementer 1, the central axis of the filter medium 31 is provided substantially along the vertical direction. Here, the central axis of the filter medium 31 is the same as the central axis A1 of the case body 10.
　濾材３１の内周に沿って、内筒３２が設けられる。内筒３２は、例えば金属製であり、略円筒形状である。内筒３２には、複数の貫通孔（図示せず）が形成される。内筒３２の中心軸は、濾材３１の中心軸と同じである。 An inner cylinder 32 is provided along the inner periphery of the filter medium 31. The inner cylinder 32 is made of, for example, metal and has a substantially cylindrical shape. A plurality of through holes (not shown) are formed in the inner cylinder 32. The central axis of the inner cylinder 32 is the same as the central axis of the filter medium 31.
　フィルタエレメント３０の上端部には、濾材３１及び内筒３２の上端面を覆うプレート３４が設けられる。プレート３４の略中央には円筒部３４ａが形成されている。円筒部３４ａの内周面は、流出路２０ｂが中央に形成された円筒部２０ｆの外周面に嵌合される。これにより、ヘッド２０がケース本体１０の開口部に取り付けられたときに、フィルタエレメント３０がケース本体１０の内部に設けられる。円筒部３４ａの内周面と円筒部２０ｆの外周面との間にはガスケット３３が設けられ、これにより円筒部３４ａの内周面と円筒部２０ｆの外周面との間から液体が漏れないようにシールされ、フィルタエレメント３０がヘッド２０に液密に設けられる。 The plate 34 which covers the upper end surface of the filter medium 31 and the inner cylinder 32 is provided in the upper end part of the filter element 30. A cylindrical portion 34 a is formed in the approximate center of the plate 34. The inner peripheral surface of the cylindrical portion 34a is fitted to the outer peripheral surface of the cylindrical portion 20f in which the outflow path 20b is formed at the center. Thereby, when the head 20 is attached to the opening of the case main body 10, the filter element 30 is provided inside the case main body 10. A gasket 33 is provided between the inner peripheral surface of the cylindrical portion 34a and the outer peripheral surface of the cylindrical portion 20f, so that liquid does not leak between the inner peripheral surface of the cylindrical portion 34a and the outer peripheral surface of the cylindrical portion 20f. The filter element 30 is liquid-tightly provided on the head 20.
　フィルタエレメント３０の高さ（ｚ方向の長さ）は、ケース本体１０の高さより低く、例えばケース本体１０の高さの２／３程度又はそれ以下である。これにより、ケース本体１０の内部には、フィルタエレメント３０の鉛直方向下方に、濾過前の燃料Ｆに含まれる水分及びスラッジ（燃料Ｆより重い）が沈殿して貯留される貯留部１０ａとなる空間が形成される。 The height of the filter element 30 (the length in the z direction) is lower than the height of the case body 10, for example, about 2/3 of the height of the case body 10 or less. Thereby, inside the case main body 10, a space serving as a storage portion 10 a in which moisture and sludge (heavier than the fuel F) contained in the fuel F before filtration is precipitated and stored below the filter element 30 in the vertical direction. Is formed.
　内部ケース４０は、略円筒形状の部材であり、ケース本体１０の高さより低い。内部ケース４０は、フィルタエレメント３０の外側かつ前記ケース本体の内側に、フィルタエレメント３０の外周面を覆うように設けられる。内部ケース４０の中心軸は、ケース本体１０の中心軸Ａ１と同一である。ケース本体１０の貯留部１０ａには対向して２個のリブ１０ｂが形成されている。したがって、リブ１０ｂの上端面と、ヘッド２０の凹部２０ｄとで内部ケース４０を挟持することで、内部ケース４０がケース本体１０の内部に設けられる。また、内部ケース４０には、フィルタエレメント３０が落下しないように内側に向けて突起４０ａが形成される。 The inner case 40 is a substantially cylindrical member and is lower than the height of the case body 10. The inner case 40 is provided outside the filter element 30 and inside the case body so as to cover the outer peripheral surface of the filter element 30. The central axis of the inner case 40 is the same as the central axis A1 of the case body 10. Two ribs 10b are formed facing the storage portion 10a of the case body 10. Therefore, the inner case 40 is provided inside the case body 10 by sandwiching the inner case 40 between the upper end surface of the rib 10 b and the recess 20 d of the head 20. Further, the inner case 40 is formed with a protrusion 40a facing inward so that the filter element 30 does not fall.
　図３において、燃料Ｆの流れを太矢印で示す。燃料タンク（図示せず）からセジメンタ１に導かれる燃料Ｆは、濾過される前の状態である。燃料Ｆは、流入路２０ａを通って、ケース本体１０の内部、ここではケース本体１０と内部ケース４０との間の空間に流入する。 In FIG. 3, the flow of the fuel F is indicated by a thick arrow. The fuel F guided from the fuel tank (not shown) to the cementer 1 is in a state before being filtered. The fuel F flows into the inside of the case main body 10, here the space between the case main body 10 and the inner case 40, through the inflow path 20 a.
　流入路２０ａは、ヘッド２０の周縁近傍に、その中心軸Ａ２が位置Ｂにおける法線方向と略一致するように形成されるため、ケース本体１０の内部、すなわちケース本体１０と内部ケース４０との間の空間に流入した燃料Ｆは、ケース本体１０の内周面及び内部ケース４０の外周面に沿って旋回しながら、重力により鉛直下向き（－ｚ方向）に移動する（サイクロン）。そのため、遠心力と重力とにより、燃料Ｆ中の水分とスラッジとが燃料Ｆから分離される。 Since the inflow path 20a is formed in the vicinity of the periphery of the head 20 so that the center axis A2 substantially coincides with the normal direction at the position B, the inside of the case body 10, that is, between the case body 10 and the inner case 40, is formed. The fuel F that has flowed into the space moves along the inner peripheral surface of the case body 10 and the outer peripheral surface of the inner case 40 and moves vertically downward (−z direction) by gravity (cyclone). Therefore, the moisture and sludge in the fuel F are separated from the fuel F by centrifugal force and gravity.
　水分及びスラッジは、燃料Ｆの主成分である油より重い。したがって、分離された水分及びスラッジは、自重により、貯留部１０ａに沈殿する。 Moisture and sludge are heavier than oil, which is the main component of fuel F. Therefore, the separated moisture and sludge are settled in the reservoir 10a due to their own weight.
　その後、燃料Ｆは、内部ケース４０の下端部の開口を通過して上方（＋ｚ方向）へ移動する。フィルタエレメント３０の下端部はプレート３５により覆われているため、上方へ移動した燃料Ｆは、フィルタエレメント３０の外周面から内側に向かって流れ、濾材３１で濾過される。貯留部１０ａに沈殿しなかったスラッジは、濾材３１で捕集される。 Thereafter, the fuel F passes through the opening at the lower end of the inner case 40 and moves upward (in the + z direction). Since the lower end portion of the filter element 30 is covered with the plate 35, the fuel F that has moved upward flows inward from the outer peripheral surface of the filter element 30 and is filtered by the filter medium 31. Sludge that has not settled in the reservoir 10 a is collected by the filter medium 31.
　濾材３１で濾過された燃料Ｆは、内筒３２の内側に流入し、流出路２０ｂを通ってセジメンタ１から流出する。セジメンタ１から流出した燃料Ｆは、燃料フィルタ（図示せず）に導かれる。 The fuel F filtered by the filter medium 31 flows into the inner cylinder 32 and flows out from the cementer 1 through the outflow path 20b. The fuel F flowing out of the cementer 1 is guided to a fuel filter (not shown).
　本実施の形態では、水分だけでなく、スラッジをも貯留部１０ａに沈殿させることができる。すなわち、通常のセジメンタの機能である水分を分離する能力に加え、スラッジ分離機能をセジメンタに付加することができる。 In this embodiment, not only moisture but also sludge can be precipitated in the reservoir 10a. That is, in addition to the ability to separate moisture, which is a function of a normal sedimenter, a sludge separation function can be added to the sementor.
　また、スラッジが貯留部１０ａに沈殿するため、燃料Ｆに含まれる全てのスラッジが濾材３１で捕集されない。したがって、濾材３１の負担を軽減（目詰まりしにくい）し、濾材３１の寿命を長くすることができる。 In addition, since sludge settles in the storage portion 10 a, not all sludge contained in the fuel F is collected by the filter medium 31. Therefore, the load on the filter medium 31 can be reduced (it is difficult to clog), and the life of the filter medium 31 can be extended.
　なお、本実施の形態では、フィルタエレメント３０の外側に内部ケース４０が設けられたが、内部ケース４０は必須ではない。内部ケース４０があることにより、スラッジ分離能力が向上するが、油水分離能力は低下する。したがって、求める性能に応じて、内部ケース４０の有無を決めればよい。 In the present embodiment, the inner case 40 is provided outside the filter element 30, but the inner case 40 is not essential. The presence of the inner case 40 improves the sludge separation capability, but reduces the oil / water separation capability. Therefore, the presence or absence of the inner case 40 may be determined according to the required performance.
　また、本実施の形態では、流入路２０ａがヘッド２０の周縁近傍に形成されるが、流入路２０ａの位置はこれに限られない。以下、セジメンタ２について説明するが、セジメンタ１と同一の部分については同一の符号を付し、説明を省略する。 In the present embodiment, the inflow path 20a is formed in the vicinity of the periphery of the head 20, but the position of the inflow path 20a is not limited to this. Hereinafter, although the segmenter 2 is demonstrated, about the part same as the segmenter 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
　図４は、変形例に係るセジメンタ２の概略を示す平面図である。図５は、セジメンタ２の概略を示す要部断面図である。図６は、セジメンタ２の概略を部分的に示す斜視図であり、要部を透視した図である。なお、図５においては、説明のため、断面を示すハッチング表示を一部省略している。 FIG. 4 is a plan view showing an outline of the cementer 2 according to the modification. FIG. 5 is a cross-sectional view of the main part showing an outline of the cementer 2. FIG. 6 is a perspective view partially showing an outline of the cementer 2 and is a view seen through a main part. In FIG. 5, for the sake of explanation, a part of hatching display showing a cross section is omitted.
　ヘッド２０Ａには、流入路２０ｅが設けられる。流入路２０ｅは、筒状の部材であり、流入路２０ｅの中心軸Ａ３は、ケース本体１０の中心軸Ａ１と直交する方向であるｘ方向に沿って設けられる。流入路２０ｅは、流入路２０ｅを延長したときにケース本体１０の中心軸Ａ１を含む位置に設けられる。 The inflow path 20e is provided in the head 20A. The inflow path 20 e is a cylindrical member, and the central axis A <b> 3 of the inflow path 20 e is provided along the x direction, which is a direction orthogonal to the central axis A <b> 1 of the case body 10. The inflow path 20e is provided at a position including the central axis A1 of the case body 10 when the inflow path 20e is extended.
　内部ケース４１は、主として、略円筒形状の円筒部４１ａと、略円錐台形状の底部４１ｂと、を有する。底部４１ｂは、円筒部４１ａの底面側の開口部を覆うように、円筒部４１ａに一体形成される。底部４１ｂの略中央には、内部ケース４１の下端部の開口である孔４１ｃが形成される。 The inner case 41 mainly has a cylindrical portion 41a having a substantially cylindrical shape and a bottom portion 41b having a substantially truncated cone shape. The bottom 41b is integrally formed with the cylindrical portion 41a so as to cover the opening on the bottom surface side of the cylindrical portion 41a. A hole 41c that is an opening at the lower end of the inner case 41 is formed in the approximate center of the bottom 41b.
　底部４１ｂは、上側（＋ｚ側）に凸となるように設けられる。底部４１ｂの下端面は、リブ１０ｂと当接する。したがって、リブ１０ｂの上端面と、ヘッド２０の凹部２０ｇとで内部ケース４１を挟持することで、内部ケース４１がケース本体１０の内部に設けられる。 The bottom 41b is provided so as to protrude upward (+ z side). The lower end surface of the bottom 41b is in contact with the rib 10b. Therefore, the inner case 41 is provided inside the case body 10 by sandwiching the inner case 41 between the upper end surface of the rib 10 b and the recess 20 g of the head 20.
　図５、６において、燃料Ｆの流れを太矢印で示す。燃料Ｆは、流入路２０ａを通って、ケース本体１０と内部ケース４１との間の空間に流入する。流入路２０ｅは、中心軸Ａ１と交差する位置に設けられるため、流入路２０ａからケース本体１０の内部に導かれた燃料Ｆは、旋回せず、重力によって落下する。落下した燃料Ｆは、底部４１ｂとケース本体１０との間から貯留部１０ａに移動する。そして、水分及びスラッジは、自重により貯留部１０ａに沈殿する。 5 and 6, the flow of the fuel F is indicated by a thick arrow. The fuel F flows into the space between the case body 10 and the inner case 41 through the inflow path 20a. Since the inflow path 20e is provided at a position intersecting with the central axis A1, the fuel F guided from the inflow path 20a to the inside of the case body 10 does not turn but falls due to gravity. The dropped fuel F moves from between the bottom portion 41b and the case body 10 to the storage portion 10a. Then, moisture and sludge are precipitated in the storage unit 10a by its own weight.
　その後、燃料Ｆは、内部ケース４１の孔４１ｃを通過して上方（＋ｚ方向）へ移動する。上方へ移動した燃料Ｆは、フィルタエレメント３０の外周面から内側に向かって流れ、濾材３１で濾過され、内筒３２の内側に流入し、流出路２０ｂを通ってセジメンタ１から流出する。 After that, the fuel F passes through the hole 41c of the inner case 41 and moves upward (+ z direction). The fuel F that has moved upward flows inward from the outer peripheral surface of the filter element 30, is filtered by the filter medium 31, flows into the inner cylinder 32, and flows out of the sedimenter 1 through the outflow path 20 b.
　本変形例によれば、渦流を発生させる場合と比べて水分とスラッジとを燃料Ｆから分離させる能力は低いが、重力によって燃料Ｆ中の水分とスラッジとを燃料Ｆから分離させることができる。 According to this modification, although the ability to separate moisture and sludge from the fuel F is low compared with the case where vortex is generated, the moisture and sludge in the fuel F can be separated from the fuel F by gravity.
　なお、本変形例のセジメンタ２は、内部ケース４１を備えるが、内部ケース４１のかわりに内部ケース４０を用いてもよい。また、セジメンタ１は、内部ケース４０を備えるが、内部ケース４０のかわりに内部ケース４１を用いてもよい。 Note that the cementer 2 of the present modification includes the inner case 41, but the inner case 40 may be used instead of the inner case 41. Further, although the cementer 1 includes the inner case 40, the inner case 41 may be used instead of the inner case 40.

FIG. 8 is a cross-sectional view of the main part showing an outline of the fuel filter 3. FIG. 9 is a perspective view partially showing an outline of the fuel filter 3, and is a view seen through a main part. FIG. 10 is an exploded perspective view of the fuel filter 3. In FIG. 8, for the sake of explanation, a part of hatching display showing a cross section is omitted. Hereinafter, although the fuel filter 3 is demonstrated, the same code | symbol is attached | subjected about the part same as the cementers 1 and 2, and description is abbreviate | omitted.
　燃料フィルタ３は、主として、ケース本体１０Ａ、ヘッド２０Ａと、フィルタエレメント７０と、フィルタエレメント５０と、内部ケース６０と、を有する。なお、ケース本体１０Ａとケース本体１０とは、高さ及び部分的な形状のみが異なり、その他は同一である。 The fuel filter 3 mainly includes a case main body 10A, a head 20A, a filter element 70, a filter element 50, and an inner case 60. The case body 10A and the case body 10 are the same except for the height and the partial shape.
　フィルタエレメント５０は、フィルタエレメント７０によりスラッジが除去された燃料Ｆを濾過するものであり、濾材が一重若しくは二重に設けられたエレメントである。フィルタエレメント５０は、主として、塵埃を除去する外側の濾材５１と、水分を除去する内側の濾材５２と、それぞれの濾材５１、５２に設けられた内筒５３、５４と、内側の濾材で除去された水分を下方（－ｚ方向）へ落下させる筒部材５５と、を有する。 The filter element 50 is for filtering the fuel F from which the sludge has been removed by the filter element 70, and is an element provided with a single or double filter medium. The filter element 50 is mainly removed by an outer filter medium 51 for removing dust, an inner filter medium 52 for removing moisture, inner cylinders 53 and 54 provided in the respective filter media 51 and 52, and an inner filter medium. And a cylindrical member 55 that drops the moisture in the downward direction (−z direction).
　濾材５１、５２は、ケース本体１０Ａに導かれた燃料Ｆを濾過する部材であり、板状の材料をひだ折りして（プリーツ状にして）略円筒形状にすることにより形成される。 The filter media 51 and 52 are members for filtering the fuel F guided to the case main body 10A, and are formed by folding a plate-like material (pleats) into a substantially cylindrical shape.
　フィルタエレメント５０の上端部には、濾材５１、５２及び内筒５３、５４の上端面を覆うプレート５６が設けられる。プレート５６の略中央には円筒部５６ａが形成されている。円筒部５６ａの内周面は、流出路２０ｂが中央に形成された円筒部２０ｆの外周面に嵌合される。これにより、ヘッド２０Ａがケース本体１０Ａの開口部に取り付けられたときに、フィルタエレメント５０がケース本体１０Ａ内部に設けられる。また、ガスケット３３により円筒部５６ａの内周面と円筒部２０ｆの外周面との間から液体が漏れないようにシールされることで、フィルタエレメント５０がヘッド２０に液密に設けられる。 At the upper end of the filter element 50, a plate 56 that covers the upper ends of the filter media 51 and 52 and the inner cylinders 53 and 54 is provided. A cylindrical portion 56 a is formed in the approximate center of the plate 56. The inner peripheral surface of the cylindrical portion 56a is fitted to the outer peripheral surface of the cylindrical portion 20f in which the outflow passage 20b is formed at the center. Thereby, when the head 20A is attached to the opening of the case main body 10A, the filter element 50 is provided inside the case main body 10A. The filter element 50 is liquid-tightly provided on the head 20 by sealing the gasket 33 so that liquid does not leak from between the inner peripheral surface of the cylindrical portion 56a and the outer peripheral surface of the cylindrical portion 20f.
　内部ケース６０は、略円筒形状の部材であり、フィルタエレメント５０を覆うように設けられる。内部ケース６０の中心軸は、鉛直方向と略平行、例えばケース本体１０Ａの中心軸Ａ１と同一である。内部ケース６０の下端には、筒部６０ａが形成される。 The inner case 60 is a substantially cylindrical member and is provided so as to cover the filter element 50. The central axis of the inner case 60 is substantially parallel to the vertical direction, for example, the same as the central axis A1 of the case body 10A. A cylindrical portion 60 a is formed at the lower end of the inner case 60.
　フィルタエレメント７０は、内部ケース６０の下端に設けられる。筒部６０ａには、フィルタエレメント７０の上端面を覆うプレート７１の略中央に形成された円筒部７１ａの内周面が嵌合される。円筒部３４ａの内周面と筒部６０ａの外周面との間は、ガスケット３６によりシールされる。これにより、フィルタエレメント７０が内部ケース６０に液密に設けられる。フィルタエレメント７０の構成は、フィルタエレメント３０と略同一であるため、説明を省略する。 The filter element 70 is provided at the lower end of the inner case 60. The cylindrical portion 60a is fitted with an inner peripheral surface of a cylindrical portion 71a formed at substantially the center of the plate 71 that covers the upper end surface of the filter element 70. A gap between the inner peripheral surface of the cylindrical portion 34a and the outer peripheral surface of the cylindrical portion 60a is sealed with a gasket 36. Thereby, the filter element 70 is liquid-tightly provided in the inner case 60. Since the configuration of the filter element 70 is substantially the same as that of the filter element 30, description thereof is omitted.
　フィルタエレメント７０とフィルタエレメント５０とは、ケース本体１０Ａの内部に、鉛直方向に並べて設けられる。例えば燃料フィルタ３では、フィルタエレメント７０の上側（＋ｚ側）にフィルタエレメント５０が設けられる。 The filter element 70 and the filter element 50 are provided in the case body 10A side by side in the vertical direction. For example, in the fuel filter 3, the filter element 50 is provided on the upper side (+ z side) of the filter element 70.
　ケース本体１０Ａの内部には、フィルタエレメント７０の鉛直方向下方に、貯留部１０ａとなる空間が形成される。貯留部１０ａに設けられたリブ１０ｂの上端面には、フィルタエレメント７０が当接する。したがって、内部ケース６０及びフィルタエレメント７０は、ヘッド２０Ａの凹部２０ｇとリブ１０ｂの上端面とにより挟持される。 In the case main body 10A, a space serving as the storage portion 10a is formed below the filter element 70 in the vertical direction. The filter element 70 abuts on the upper end surface of the rib 10b provided in the storage portion 10a. Therefore, the inner case 60 and the filter element 70 are sandwiched between the recess 20g of the head 20A and the upper end surface of the rib 10b.
　図８、９において、燃料Ｆの流れを太矢印で示す。燃料タンク（図示せず）から燃料フィルタ３に導かれる燃料Ｆは、濾過される前の状態である。燃料Ｆは、流入路２０ｅを通って、ケース本体１０Ａの内部、ここではケース本体１０Ａと内部ケース６０との間の空間に流入する。 8 and 9, the flow of the fuel F is indicated by a thick arrow. The fuel F guided from the fuel tank (not shown) to the fuel filter 3 is in a state before being filtered. The fuel F flows through the inflow path 20e into the inside of the case main body 10A, here, the space between the case main body 10A and the inner case 60.
　ケース本体１０Ａと内部ケース６０との間の空間に流入した燃料Ｆは、重力により鉛直下向き（－ｚ方向）に移動する。フィルタエレメント７０の外側において、燃料Ｆ中の水分Ｗとスラッジとが燃料Ｆから分離され、水分Ｗとスラッジとが分離された燃料Ｆがフィルタエレメント７０を外周面から内側に向かって流れる。 The fuel F that has flowed into the space between the case body 10A and the inner case 60 moves vertically downward (−z direction) due to gravity. Outside the filter element 70, the water W and sludge in the fuel F are separated from the fuel F, and the fuel F from which the water W and sludge are separated flows from the outer peripheral surface toward the inside.
　水分Ｗ及びスラッジは、燃料Ｆの主成分である油より重い。したがって、分離された水分Ｗ及びスラッジは、自重により、ケース本体１０Ａとフィルタエレメント７０との間の空間や、リブ１０ｂとリブ１０ｂとの間の空間を通って、ケース本体１０Ａの貯留部１０ａに沈殿する（図８、９の２点鎖線参照）。なお、貯留部１０ａに沈殿しなかったスラッジは、燃料Ｆがフィルタエレメント７０を通過するときにフィルタエレメント７０で捕集される。 Moisture W and sludge are heavier than oil, which is the main component of fuel F. Therefore, the separated water W and sludge pass through the space between the case main body 10A and the filter element 70 and the space between the rib 10b and the rib 10b by the dead weight to the storage portion 10a of the case main body 10A. It precipitates (see the two-dot chain line in FIGS. 8 and 9). The sludge that has not settled in the reservoir 10 a is collected by the filter element 70 when the fuel F passes through the filter element 70.
　フィルタエレメント７０で濾過された燃料Ｆは、内部ケース６０の内側を通ってフィルタエレメント５０の外周に供給される。フィルタエレメント５０の下端部はプレート５７、５８により覆われているため、上方へ移動した燃料Ｆは、濾材５１、５２の外周面から内側に向かって流れる。フィルタエレメント５０で濾過された燃料Ｆは、流出路２０ｂを通って燃料フィルタ３から流出する。燃料フィルタ３から流出した燃料Ｆは、エンジン（図示せず）に導かれる。 The fuel F filtered by the filter element 70 is supplied to the outer periphery of the filter element 50 through the inside of the inner case 60. Since the lower end portion of the filter element 50 is covered with the plates 57 and 58, the fuel F that has moved upward flows inward from the outer peripheral surfaces of the filter media 51 and 52. The fuel F filtered by the filter element 50 flows out from the fuel filter 3 through the outflow path 20b. The fuel F flowing out from the fuel filter 3 is guided to an engine (not shown).
　また、貯留部１０ａに沈殿しなかった水分Ｗは、フィルタエレメント５０の内側の濾材５２で捕集される。この水分Ｗは、自重により、筒部材５５の内部を通って、ケース本体１０Ａの貯留部１０ａに沈殿する（図５太破線参照）。 Further, the water W that has not settled in the reservoir 10 a is collected by the filter medium 52 inside the filter element 50. The moisture W passes through the inside of the cylindrical member 55 by its own weight and settles in the storage portion 10a of the case main body 10A (see the thick broken line in FIG. 5).
　本実施の形態によれば、セジメンタの機能であるスラッジ分離機能と、燃料フィルタの油水分離機能とを一体とすることができる。 According to the present embodiment, the sludge separation function that is the function of the cementer and the oil / water separation function of the fuel filter can be integrated.
　なお、セジメンタ１、２は、フィルタエレメント３０を備えるが、フィルタエレメント３０のかわりにフィルタエレメント５０を備えてもよい。 In addition, although the cementers 1 and 2 are provided with the filter element 30, you may provide the filter element 50 instead of the filter element 30. FIG.
　以上、この発明の実施形態を、図面を参照して詳述してきたが、具体的な構成はこの実施形態に限られるものではなく、この発明の要旨を逸脱しない範囲の設計変更等も含まれる。当業者であれば、実施形態の各要素を、適宜、変更、追加、変換等することが可能である。 The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within a scope not departing from the gist of the present invention are included. . A person skilled in the art can appropriately change, add, or convert each element of the embodiment.
　また、本発明において、「略」とは、厳密に同一である場合のみでなく、同一性を失わない程度の誤差や変形を含む概念である。例えば、「略平行」とは、厳密に平行の場合には限られず、例えば数度程度の誤差を含む概念である。また、例えば、単に平行、直交、一致等と表現する場合において、厳密に平行、直交、一致等の場合のみでなく、略平行、略直交、略一致等の場合を含むものとする。また、例えば、「鉛直方向に略沿って設けられる」とは、鉛直方向に沿う場合と、鉛直方向と数度程度の誤差を含む方向に沿う場合とを含む概念である。 Further, in the present invention, “substantially” is a concept that includes not only a case where they are exactly the same but also errors and deformations that do not lose the identity. For example, “substantially parallel” is not limited to being strictly parallel, but is a concept including an error of, for example, several degrees. Further, for example, when simply expressing as parallel, orthogonal, coincidence, etc., not only strictly parallel, orthogonal, coincidence, etc., but also include cases of substantially parallel, substantially orthogonal, substantially coincidence, etc. Further, for example, “provided substantially along the vertical direction” is a concept including a case along the vertical direction and a case along the direction including the vertical direction and an error of about several degrees.
　また、本発明において「近傍」とは、基準となる位置の近くのある範囲（任意に定めることができる）の領域を含むことを意味する。例えば、上端近傍という場合に、上端の近くのある範囲の領域であって、上端を含んでもいても含んでいなくてもよいことを示す概念である。 Also, in the present invention, “neighboring” means including an area in a certain range (which can be arbitrarily determined) near the reference position. For example, in the case of the vicinity of the upper end, it is a concept indicating that the region is in a certain range near the upper end and may or may not include the upper end.
