INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a fuel supply device disposed in a fuel tank of a fuel pump. [Prior Art] A fuel system stored in a fuel phase of a vehicle is fueled by a fuel Pumped into the engine room, in order to filter impurities in the fuel, a filter device for filtering the fuel in the fuel tank is passed through the suction port of the fuel pump. In the lower side of the filter material of the filter device, a filter device having a resin material frame member is provided. The German Patent No. DE 3609905 (Patent Document -) is known as the 'Knowledge'. The member is welded to the filter material or embedded on the filter material, so that it takes a lot of labor. ^衣一又, as disclosed in Japanese Laid-Open Patent Publication No. 2000-246028 (Patent Document 1), discloses that a plurality of (multi-layer) filter materials are welded by spot welding (ie, spot welding), but because of the fusion welding point thereof Small, the filter material below the suction port of the fuel pump will often be the suction force of the pump and the whole or the most (10) is concavely deformed. In this case, the suction force of the fuel pump will increase the burden, resulting in the durability and service life of the plastic and fuel pump. In view of the problems of the above-mentioned prior art, there is provided a filter device which is superior in durability to the above-mentioned prior art in that the use of the material pump is better than the above-mentioned problems. The solution provided by the present invention is as follows: The invention described in claim 1 is a filter device for setting a suction port of a body fruit, and a filter material formed of a resin fiber. a fluid device, characterized in that: the filter device has a suction portion formed on the filter member for communicating the internal space with the suction port of the above 5200848143; and facing the filter member The molten solidified portion formed by melting a part of the suction portion is at a position opposite to the suction portion of the suction port of the communication pump, and the filter material is susceptible to the relationship of the suction force (suction force) generated by the pump. The influence of the attraction force causes a bending deformation to the suction portion, and an adsorption phenomenon attached to the suction portion sometimes occurs. In response to this, the invention of the request item is in the face of the filter material. The position is provided with a melt-solidified portion formed by melting the filter material. Since the fluid cannot flow into the interior through the melt-solidified portion, there is no straight line in which the fluid flows directly from the position facing the suction port to the suction port of the fruit. The flow of the liquid is generated, and only flows from the periphery of the suction portion into the suction port of the pump. This flow pattern can reduce the suction force of the pump and effectively suppress the deformation of the portion of the filter and the material. It can suppress the phenomenon that the filter material is sucked and sucked = the phenomenon of inhaling σ, which can reduce the pressure loss of the filter and the material, and the service life (durability) of the pump. The invention described in ifi2 is 'Yu The filter assembly member described in claim 1 is formed by the splicing and fixing, and the molten and solidified portion is formed larger than the point refining portion.

又，除此之外，也可藉雷射之熱熔接方法形成熔融固化 部48。雷射頭（未圖示）可設成對過濾材16平行移動，或 將載置過;慮材16之固定具（未圖示）設成可水平移動，而將雷 射光照射於過濾、材16預定形成熔融固化部48及點溶接部 之位置即可。再者，除上述方法之外，利用感應熱 等加熱過濾材16並加以熔融亦可。 …、U 其次’就本發明實施形態之過濾裝置之作用加以說明： 如第4圖（A)、（B)所示，本實施形態中，過濾裝置之位 於面對與燃料泵12(參照第1圖）之抽吸口連通之吸入口 22 之位置設有在夾持部3〇上所設三個圓弧狀肋條38上呈相互 200848143 架橋連接之Y字狀熔融固化部48。 過濾材16之與燃料泵12之抽吸口相對之位置受到燃料 泵12之抽吸力最大，因此，如第6圖所示，過濾材16有被 吸而向吸入口 22側成凹陷狀彎曲變形之現象發生之可能。 為此，在過濾材16之面對吸入口 22之位置設置熔融固 化部48，使燃料無法透過此熔融固化部48流入内部，因此， 燃料不會產生從面對吸入口 22之位置直接流向燃料泵12之 抽吸口側之略呈直線狀流（參照第6圖），只有形成自吸入口 22之周圍呈環流狀流流入燃料泵12之抽吸口（參照第4圖 (Β))。 於疋’可有效抑制過濾材16在面對吸入口 22之位置之 部份發生如前述之呈凹陷狀之彎曲變形，遂可減低過濾材16 之壓力損失。提高燃料泵12之使用壽命。 又，將熔融固化部48之形狀形成γ字形，使以面對吸入 口 22部份為中心呈輻射狀延伸而將各條直線延伸部相連成一 體之構造，故可增強過濾材16之熔融固化部份之強度。又， 熔融固化部48之延伸部之前端部恰擱置在夾持部3〇上突設 之圓弧狀肋條38之頂面’使各圓弧狀肋條38呈相互搭橋狀， 因此，可進一步加強熔融固化部48之強度，而有效抑止過濾 材16之撓曲變形。 〜 又’熔融固化部48除上述Υ字形之外，亦可如第7圖（a)、 (Β)所示，亦可在與吸入口 22相對之位置上設置直徑大於點 熔接部46之圓形或大點狀熔融固化部66。在此情形下，'仍 比未设置任何溶融固化部66之過濾材16可提高該正對吸入 口 22部份之過濾材16之強度。 與燃料泵12之抽吸口相通之吸入口 22相對部份之過濾 材16因受到燃料泵12之抽吸力最大之關係，在該部份設^ 熔融固化部66當然能比未設此熔融固化部66之情形，可抑 制過濾材16在此部份發生凹陷或撓曲變形。 ’ 11 200848143 対接部46及熔關化部66之面積取大時，過 濾裝置14之過慮面積將會減少相當於該增大部份之 於點熔接部46係為了使各樹職維1βΑ ，結合為-體之目的而形成，從财 f，f 體之流動改變方向之目的而設置，自需要保; 小，如此之故，熔融固化部66需大於點熔接部46。 嶋、⑻所示，也可在過騎16上設置 搭接在夾持。卩30之三個圓弧狀肋條38之頂面之 錄線段雜關化部68。恤脑固化 =8跨接於S1弧狀肋條38之頂面，環繞圓弧狀肋條38之頂 m之韻材16之強度即可增強，與未設置親融固化部 比之情形比較，可有效抑制過濾材16之凹陷變形。 一又，不限於直線狀熔融固化部48、68，亦可如第9圖⑴ 形成％狀炫融固化部7〇，此時，該環狀溶融固化部70 應跨接於各圓弧狀肋條38之頂面。 j，第9圖（Β)所示，亦可形成具有内環72與外環％之 $城之熔融固化部75。在此例中，圓弧狀肋條38係配 置於内，72與外環74之間，但如使内環72或外環74甲任 方重豐於圓孤狀肋條38之頂面亦可，若使内環π與外環 74兩者皆重疊於圓弧狀肋條38之頂面當然亦可行。/、" 又，將溶融固化部形成多條直線交叉之形狀亦可。第9 圖（c)顯示具有十字狀之熔融固化部76，在此情形下，如使 22之中心無融固化部76之二直線之交點一致，如 =不，、縣固化部76便成為只有—直線搭接於—個圓弧狀 肋條38之頂面。 一為了使能平均搭接各個圓弧狀肋條38之頂面，可將直線 位置與吸入口 22之中心位置錯開，或將圓弧狀肋條38 叹成相隔90度，即具有四個圓弧狀肋條38，而使各直線能 12 200848143 搭接於各圓孤狀肋條38之頂面，如此構成時，更能提高過滤 材16之強度，並更有效抑制過濾材16之變形。 又’熔融固化部之構成除了連續之直線、環狀之外，亦 可如第9圖（D)所示，設成多個連續排列之點狀熔融固化部 78，此外，在此例中，熔融固化部係分別以線、環、點狀之 一種單獨形成，如將此等之二種或二種以上組合形成，熔融 固化部亦可行。藉此熔融固化部之構成，可獲得能降低過濾 材16之壓力損失，而有致抑制過濾材16之變形之熔融固& 部之適當形狀。 又，在本實施形態中，係就做為過濾燃料用之過濾裝置 14加以說明，但顯然可知過濾之流體並不限於燃料，$為種 種流體，因此，構成過濾材16之樹脂纖維i6A、16B、16C、 ’纖維網目、線徑等可依所用之流體之種類而適 备選擇使用或加以變化。 又’在本實施形態中，過滤裝置14係採用長方形過料 L/j對折後將其外緣雜接則彡成触體，但實施時，‘並 :::對折，如採用上面用及下面用之過濾材，秋後 將此上面用及下面用之過濾材之外緣部 盍g 、 袋狀體亦可行。 1仰up接以形成 13 200848143 【圖式簡單說明】 之整稀備有本剌實施雜之喊裝置之燃料箱 =2圖表示本發明實施形態之過濾裝置之立體圖。 剖視圖本發明實施賴之過濾裝置之過濾材之 '、中（Α_)為熔接前，（B)為熔接後之狀態。 f圖表示構成本發明實施形態之過濾裝置之主要部价 大If月圖，其中（A)為俯視圖，⑻為剖視圖。 份^^構成本㈣實絲11之過舰置之過遽材之 比示魏明本糾實細彡狀過雜置之作用之 形例L7大圖圖表矛 楚β 二中CA)為俯視圖，（β)為剖視圖。 弟8圖絲為制本發 視圖，⑻為= 200848143 【主要元件符號說明】 10 燃料箱 12 燃料泵 14 過濾裝置 16 過濾材 16A，16B，16C，16D 樹脂纖維(過遽材） 18 骨架部件 20 孔部 22, 34 吸入口（吸入部） 24 開口部 28 管接頭 30,32 夾持部 36 環狀肋條 38 圓弧狀肋條 40 骨架 42 補強肋條 44 内部空間 46 點熔接部 48, 66, 68, 75, 76 熔融固化部 70 雙重環狀熔融固化部 72 内環(熔融固化部） 74 外環(熔融固化部） 78 點狀熔融固化部 15Further, in addition to this, the melt-solidified portion 48 may be formed by a laser thermal fusion bonding method. The laser head (not shown) may be arranged to move the filter material 16 in parallel or to be placed; the fixture 16 (not shown) of the material 16 is arranged to be horizontally movable, and the laser light is irradiated to the filter and the material. It suffices that the position of the melt-solidified portion 48 and the point-melting portion is predetermined. Further, in addition to the above method, the filter material 16 may be heated by induction heat or the like and melted. ..., U Next, the action of the filter device according to the embodiment of the present invention will be described. As shown in Fig. 4 (A) and (B), in the present embodiment, the filter device is located facing the fuel pump 12 (see The suction port 22 through which the suction port is connected is provided with a Y-shaped melt-solidified portion 48 which is connected to each other by the 200848143 bridge on the three arc-shaped ribs 38 provided on the nip portion 3A. The position of the filter member 16 opposite to the suction port of the fuel pump 12 is maximized by the suction force of the fuel pump 12. Therefore, as shown in Fig. 6, the filter material 16 is sucked and bent toward the suction port 22 side. The phenomenon of deformation occurs. For this reason, the melt-solidified portion 48 is provided at a position facing the suction port 22 of the filter material 16 so that the fuel cannot flow into the inside through the melt-solidified portion 48, so that the fuel does not flow directly from the position facing the suction port 22 to the fuel. A slightly straight flow (see Fig. 6) on the suction port side of the pump 12 is formed only in a suction port that flows into the fuel pump 12 in a circulating flow from the periphery of the suction port 22 (see Fig. 4 (Β)). The 疋' can effectively suppress the bending deformation of the filter material 16 at a position facing the suction port 22 as described above, and the pressure loss of the filter material 16 can be reduced. Increase the service life of the fuel pump 12. Further, the shape of the melt-solidified portion 48 is formed into a γ-shape, and the respective linear extension portions are integrally formed to extend radially around the portion facing the suction port 22, so that the melt-solidification of the filter material 16 can be enhanced. Partial strength. Further, the front end portion of the extending portion of the melt-solidified portion 48 is placed on the top surface of the arc-shaped rib 38 protruding from the nip portion 3, so that the arc-shaped ribs 38 are bridged to each other, thereby further strengthening The strength of the solidified portion 48 is melted, and the flexural deformation of the filter material 16 is effectively suppressed. Further, the 'melt-curing portion 48 may have a diameter larger than the point of the spot-welding portion 46 at a position opposite to the suction port 22, in addition to the above-described U-shape. A shape or a large spot-like melt-solidified portion 66. In this case, 'the strength of the filter material 16 which is partially opposed to the suction port 22 can be increased more than the filter material 16 which is not provided with any molten solidification portion 66. The filter material 16 of the opposite portion of the suction port 22 communicating with the suction port of the fuel pump 12 is subjected to the maximum suction force of the fuel pump 12, and in this portion, the melt-solidified portion 66 can of course be melted. In the case of the curing portion 66, it is possible to suppress the concave or flexural deformation of the filter material 16 at this portion. ' 11 200848143 When the area of the splicing portion 46 and the smelting portion 66 is increased, the excess area of the filtering device 14 is reduced by the amount corresponding to the enlarged portion of the point welding portion 46 in order to make each tree dimension 1βΑ The combination is formed for the purpose of the body, and is set for the purpose of changing the direction of the flow of the f, f body, and is required to be self-contained; small, so that the melt-solidified portion 66 needs to be larger than the spot-welding portion 46.嶋, (8), can also be placed on the over-riding 16 to overlap the clamp. The line segment isolating portion 68 of the top surface of the three arcuate ribs 38 of the crucible 30. The brain is solidified = 8 is connected to the top surface of the S1 arcuate rib 38, and the strength of the rhyme material 16 surrounding the top of the arcuate rib 38 can be enhanced, which is effective compared with the case where the intimate solidified portion is not provided. The dent deformation of the filter material 16 is suppressed. Further, it is not limited to the linear melt-solidified portions 48 and 68, and the %-shaped fused solidified portion 7〇 may be formed as shown in Fig. 9 (1). At this time, the annular molten solidified portion 70 should be bridged to each of the arc-shaped ribs. The top of 38. j, as shown in Fig. 9 (Β), a molten solidified portion 75 having an inner ring 72 and an outer ring % may be formed. In this example, the arcuate ribs 38 are disposed between the inner and outer rings 74, but if the inner ring 72 or the outer ring 74 is heavy on the top surface of the round ribs 38, It is of course also possible for both the inner ring π and the outer ring 74 to overlap the top surface of the arcuate rib 38. /, " Further, the molten solidified portion may be formed into a plurality of straight intersecting shapes. Fig. 9(c) shows a melt-solidified portion 76 having a cross shape. In this case, if the intersection of the two straight lines of the center of the unsolidified portion 76 is the same, if not, the county solidified portion 76 becomes only - Straight line is attached to the top surface of the arcuate rib 38. In order to enable the average overlapping of the top surfaces of the arcuate ribs 38, the linear position may be offset from the center position of the suction port 22, or the arcuate ribs 38 may be slanted by 90 degrees, that is, having four arc shapes. The ribs 38 allow the linear energy 12 200848143 to overlap the top surface of each of the round ribs 38. When constructed, the strength of the filter material 16 can be further improved, and the deformation of the filter material 16 can be more effectively suppressed. Further, in addition to the continuous straight line and the ring shape, the melt-solidified portion may be formed as a plurality of dot-like melt-solidified portions 78 which are continuously arranged as shown in Fig. 9 (D), and in this example, Each of the melt-solidified portions is formed of a single wire, a ring, or a dot, and two or more of these may be combined to form a melt-solidified portion. By the configuration of the melt-solidified portion, it is possible to obtain an appropriate shape of the melt-solid portion which can reduce the pressure loss of the filter material 16 and suppress the deformation of the filter material 16. Further, in the present embodiment, the filter device 14 for filtering fuel is described. However, it is apparent that the filtered fluid is not limited to fuel, and $ is a variety of fluids. Therefore, the resin fibers i6A and 16B constituting the filter material 16 are used. , 16C, 'Fiber mesh, wire diameter, etc. can be selected or used depending on the type of fluid used. Further, in the present embodiment, the filter device 14 is formed by folding the rectangular material L/j and folding the outer edge thereof into a contact body. However, when it is implemented, the combination of the same and the following is used. The filter material can be used for the outer edge of the filter material and the bag body after the fall. 1 Yang up and connected to form 13 200848143 [Simplified description of the drawings] The fuel tank of the present invention is provided with a fuel tank.
