在電動燃料泵P的泵底部1 2 E上，蒸氣排出孔1 2 D有 開口 1 2 D a其開口向著下方；在開口 1 2 D a的周圍，設有 從泵底部1 2 E向下方突出的大致為U字形的分隔壁1 4。 分隔壁1 4的開口 1 4 A向著側面。 另外，在泵的底部1 2 E上設有向下方突出的燃料吸入 通路1 2 C，在燃料吸入通路1 2 C的外周上，設有面向下 方的繫止臺階部1 2 C a。另外，在泵底部1 2 E上設置向下 方突出的支承加厚部1 5，而支承加厚部1 5係在燃料吸 入通路1 2 C的側面且具有面向下方的繫止臺階部1 5 a。 另外，上述固定部分12Ca，15a從泵底部12E的突出 雨度係形成為相同南度。 元件符號1 6為面向泵底部1 2 E配置的呈厚壁圓板形的 橡膠板，它作成與泵底部1 2 E的形狀大致相同的圓板形。 另外，在橡膠板1 6上作出從橡膠板1 6的上表面1 6 A 向下凹入的凹部1 6 B，該凹部1 6 B圍繞分隔壁1 4的外周 且凹部1 6 B的底部1 6 B a與蒸氣排出孔1 2 D的開口 1 2 D a 312/發明說明書(補件)/92-09/92117245 200415304 相對配置，凹部1 6 B的開口 1 6 B b向著側面。（凹部1 6 B 的開口 1 6 B b和分隔壁1 4的開口 1 4 A係沿同一個方向開 口 。） 另外，在橡膠板16上設置一個從上表面16A向著下表 面1 6 C穿過的放出孔1 6 D。該放出孔1 6 D的形狀作成可 插入燃料吸入通路1 2 C和支承加厚部1 5的孔形。 過濾器F由插入燃料吸入通路1 2 C的外圓周上的燃料 流路加厚部1 7和作成網眼狀的過濾部（未圖示）構成。 在燃料流路加厚部1 7的上端，形成向著側面延伸的凸緣 1 7 A，並且，在凸緣1 7 A上穿設過濾器的安裝孔1 7 B。 另外，從支承支架1 1的下端向水平方向折曲形成的底 板1 1 A，形成面向大致整個電動燃料泵P的泵底部1 2 E 的形狀。在該底板1 1 A上形成至少可插通燃料吸入通路 12C的放出孑L llAa。 電動燃料泵P是如下這樣安裝在支承支架1 1上的。首 先，將過濾器F安裝在電動燃料泵P上。此為將過濾器 F的燃料流路加厚部1 7插入從電動燃料泵P的泵底部 1 2 E突出的燃料吸入通路1 2 C上者，這樣，凸緣1 7 A頂 接於燃料流路加厚部1 7的繫止臺階部1 2 C a和支承加厚 部1 5的繫止臺階部1 5 a，這時，凸緣1 7 A的過濾器安裝 孔1 7 B插入配置於支承加厚部1 5中。 在這種狀態下，將推壓螺母1 8嵌入配置在支承加厚部 1 5中，這樣，可將過濾器F安裝在電動燃料泵P上。其 次，向著電動燃料泵P的泵底部1 2 E安裝橡膠板1 6。即： 312/發明說明書(補件)/92-09/92117245 200415304 橡膠板1 6的放出孔1 6 D a通過過濾器F的燃料流路加厚 部1 7、燃料吸入通路1 2 C和支承加厚部1 5的外周，使 橡膠板16的上表面16A頂接於泵底部12E。另一方面， 開口向著橡膠板1 6的上表面1 6 A的凹部1 6 B，圍繞從泵 底部1 2 E突出的分隔壁1 4的外周而配置，這時，凹部 1 6 B的底部1 6 B a蓋閉分隔壁1 4的下方開口 ，同時面向 蒸氣排出孔1 2 D的開口 1 2 D a而配置。 另外，過濾器F和橡膠板1 6配置在電動燃料泵P的泵 底部1 2 E上，在這個狀態下，將橡膠板1 6的下表面1 6 C 配置在支承支架1 1的底板1 1 A上，同時，在這個狀態下 安裝後，用緊固帶12F將電動燃料泵P固定在支承支架 1 1上。 當利用這種現有的車輛用之燃料供給裝置時，在發動 機運轉中或電動燃料泵驅動中，當支承支架1 1或電動燃 料泵P振動時，電動燃料泵P在上下方向的振動，被橡 膠板1 6吸收。 另外，在泵室12A内，由於葉輪12B轉動，在泵室12A 内產生蒸氣，該蒸氣在泵室1 2 A内，與壓力升高的一部 分燃料一起從蒸氣排出孔1 2 D的開口 1 2 D a向外部排出， 含有此蒸氣的燃料，一旦與橡膠板1 6的凹部1 6 B的底部 1 6 B a衝突後，其流動方向向側面改變，從分隔壁1 4的 開口 1 4 A向側面排出。 因此，不會有含有蒸氣的壓力升高的燃料與過濾器F 的過濾部衝突、引起使過濾部破損和變形。 312/發明說明書(補件)/92./92117245 200415304 【發明内容】 (發明所欲解決之問題） 當採用現有的燃料供給裝置時，因為需要在橡膠板1 6 上作出圍繞分隔壁1 4且面向蒸氣排出孔1 2 D的凹部 1 6 B，因此橡膠板1 6需要作成覆蓋大致全部電動燃料泵 P的泵底部1 2 E的形狀。這樣，橡膠板1 6尺寸大，不能 降低零件的成本。 即，由於橡膠板1 6尺寸大，橡膠板1 6的模具昂貴， 同時材料費提高。特別是，在使用燃料中含有酒精的汽 油燃料的情況下，要使用含有氟的橡膠材料，這樣，材 料費更大大提高。 另外，由於從蒸氣排出孔1 2 D的開口 1 2 D a噴出的燃料 直接與橡膠板1 6的凹部1 6 B的底部1 6 B a衝突，促進了 橡膠質量的劣化，這是不好的。 另外，由於橡膠板1 6尺寸大’支承橡膠板1 6的一側 的底板1 1 A的形狀也要大，因此，支承支架1 1的重量增 加。 本發明是考慮到上述問題而提出的，其目的在於提供 一種具有吸收電動燃料泵和支承支架的振動的功能，和 使從蒸氣排出孔排出的含有蒸氣的燃料的流動方向可向 側面改變功能的小型且廉價的燃料供給裝置。 (解決問題之手段） 為了達到上述目的，本發明的車輛用之燃料供給裝 置，係在具有：蓋閉燃料箱的開口的蓋體；以泵底部面 10 312/發明說明書(補件)/92-09/92117245 200415304 對著固定於蓋體上的支承支架的底板的狀態而配置，同 時，在泵底部用以連設於泵室的燃料吸入通路；開設有 蒸氣排出孔，且安裝在支承支架上的摩擦渦流式電動燃 料果，以及與電動燃料果的燃料吸入通路連接的過滤裔 的車輛用之燃料供給裝置中，其特徵為： 過濾器具備 插入配置在燃料吸入通路中的燃料流路加厚部；及備 有從燃料流路加厚部的上端向側面延伸的凸緣的同時， 還具備設於該凸緣上的過濾器安裝孔和蒸氣排出孔相對 面部， 通過將上述過濾器的燃料流路加厚部插入配置在電動 燃料果的燃料吸入通路中’將過滤裔安裝孔插入配置在 從泵底部向下方突出的支承加厚部中，使蒸氣排出孔相 對面部與蒸氣排出孔的開口相對配置，使推壓螺母與從 凸緣的過濾器安裝孔突出的支承加厚部嵌合，從而，將 過濾器安裝在電動燃料泵上， 另一方面，在支承支架的底板上，穿設絕緣體安裝孔， 同時，將用彈性材料製成的筒狀絕緣體插入配置在該絕 緣體安裝孔中，將上述絕緣體配置在支承支架的底板和 電動燃料泵的泵底部之間。 (作用） 採用本發明的車輛用之燃料供給裝置時，通過將穿設 於凸緣上的過濾器安裝孔插入支承加厚部中，然後，將 推壓螺母與支承加厚部嵌合，可將過濾器安裝在電動燃 312/發明說明書(補件)/92-09/92117245 200415304 料泵上。 又，由於設在過濾器凸緣上的蒸氣排出孔相對面部與 蒸氣排出孔的開口相對配置，從蒸氣排出孔的開口排出 的含有蒸氣的燃料與蒸氣排出孔相對面部衝突，可使流 動方向向側面改變。 另外，由於在過濾器的蒸氣排出孔相對面部設有將從 蒸氣排出孔的開口排出的含有蒸氣的燃料的流動方向向 側面改變的功能，因此，可使放置在電動燃料泵的泵底 部和支承支架之間的，用橡膠材料製成的絕緣體形狀尺 寸減小，還可使與絕緣體的另一端對應的支承支架的底 板尺寸減小。 【實施方式】 以下，根據圖1和圖2來說明本發明的車輛用之燃料 供給裝置的一個實施例。 圖1為安裝在支承支架上的電動燃料泵的底部附近的 主要部分的縱剖面圖，圖2為沿著圖1中的C _ C線所作 的橫剖面圖。 由於電動燃料泵P使用與目前相同的結構，因此，使 用相同的元件符號，並省略說明。 過濾器F具有插入配置在燃料吸入通路1 2 C中的燃料 流路加厚部1 ;在該燃料流路加厚部1的下端，具有過 遽燃料的過滤·部（未圖不在燃料流路加厚部1的上端 具有平板形的凸緣1 A。 凸緣1 A由於具有過濾器安裝孔1 B和蒸氣排出孔相對 12 312/發明說明書(補件)/92-09/92117245 200415304 面部1 C，過濾器安裝孔1 B貫穿凸緣1 A，因此該安裝孔 可以插入從泵底部1 2 C突出出來的支承加厚部1 5中。 另外，蒸氣排出孔相對面部1 C作成可蓋閉U字形的分 隔壁1 4的下方開口的形狀。該分隔壁的開口是從泵底部 12E向著下方的。 元件符號2為由橡膠材料製成的筒狀的絕緣體，它由 大直徑部2 A和小直徑部2 B構成。大直徑部2 A作成部分 地面向泵底部1 2 E的形狀，即可作成圓筒形或棱柱形， 小直徑部2B則作成圓筒形。例如，大直徑部2A的直徑 為10mm，小直徑部2B的直徑為4mm。（但是，不限於這 個數值）。支承支架3的上端固定在圖示的蓋體10上， 下端向側面折曲，形成底板3A。 底板3 A作成叉形，同時，使絕緣體2面向電動燃料泵 P的泵底部1 2 E的一部分配置。 在上述底板上，穿設兩個絕緣體安裝孔3B。 過濾器F按以下方法安裝在電動燃料泵P上。過濾器 F的燃料流路加厚部1插入配置在燃料吸入通路1 2 C 中，過濾器F的凸緣1 A的上表面，頂接配置於燃料流路 加厚部1的繫止臺階部1 2 C a和支承加厚部1 5的繫止臺 階部1 5 A。 在凸緣1 A的這種頂接狀態下，將支承加厚部1 5插入 配置在過濾器安裝孔1 B中，蒸氣排出孔相對面部1 C蓋 閉從泵底部1 2 E向下方突出的分隔壁1 4的下部開口。 蒸氣排出孔相對面部1 C，與開口在分隔壁1 4的内側 13 312/發明說明書(補件)/92-09/92117245 200415304 的蒸氣排出孔1 2 D的開口 1 2 D a相對配置。 另外，由於推壓螺母1 8嵌合配置在通過凸緣1 A、向 下方突出來的支承加厚部1 5中，這樣，可使過濾器F 向著電動燃料泵P的泵底部12E安裝。 另外，由於絕緣體2配置在支承支架3的底板3A上， 因此，各絕緣體2的兩個小直徑部2B，插入配置在穿過 底板3 A的各個絕緣體安裝孔3 B内，這樣，可分別將絕 緣體2 (具體為大直徑部2 A )支承在各個底板3 A上。 另外，安裝著過濾器F的電動燃料泵P，安裝在支承 支架3上，電動燃料泵P的泵底部12E面對著底板3A 而配置。在這個狀態下，可用圖3所示的緊固帶1 2 F， 將過濾器F固定在支承支架3上。 在這種固定狀態下，絕緣體2的大直徑部2A的上表面 接近配置在泵底部1 2 E上，或頂接配置於泵底部1 2 E。 利用以上結構的本發明燃料供給裝置，可驅動電動燃 料泵P，由過濾器F的過濾部將燃料箱T内的燃料中的 異物除去，這種燃料，通過燃料流路加厚部1的内側和 燃料吸入通路12C，被吸入泵室12A内，在泵室12A中， 壓力升高的燃料通過燃料輸出通路1 2 G、粗濾器S和輸 出管1 3而供給發動機。 這時，在泵室1 2 A内產生的蒸氣與燃料一起從蒸氣排 出孔1 2 D的開口 1 2 D a向下方喷出。含有蒸氣的燃料，在 和與過濾器F的蒸氣排出孔相對面部1 C衝突後，向外側 改變流動方向，從向左側開口的分隔壁1 4的開口 1 4 A， 14 312/發明說明書(補件)/92-09/92117245 200415304 向左側排出。 因此，含有蒸氣的升壓的燃料，不與配置在過濾器F 的燃料流路加厚部1的下端的過濾部衝突，不會損傷過 濾部和使過濾部變形。 另一方面，在發動機之運轉中，電動燃料泵P和支承 支架3振動，其中，電動燃料泵P在長度方向的振動， 可被絕緣體2吸收。 以上，有下列幾點值得注意。 即··由於在過濾器F的凸緣1 A上具有過濾器安裝孔 1 B和蒸氣排出孔相對面部1 C，這樣，可以得到過濾器F 在電動燃料泵P上安裝的功能，和改變含有蒸氣的燃料 流動方向的功能。 另外，由於具有上述過濾器安裝孔1 B和蒸氣排出孔相 對面部1 C的凸緣1 A，在形成過濾器F時，用合成樹脂 材料整體射出成型，因此過濾器F的製造成本不會提高。 又，如上所述，通過使過濾器F具有改變蒸氣的流動 方向的功能，絕緣體2只需具有防振功能就可以。這樣， 絕緣體2可以作成部分地與泵底部1 2 E接觸的形狀，因 此，可以使絕緣體2的尺寸大大減小。 因此，即使利用昂貴的橡膠材料來製造絕緣體2時， 因所用的材料量少，因此絕緣體2的製造成本也不會大 幅提南。 另外，由於絕緣體2的尺寸減小，支承絕緣體2的支 承支架3的底板3 A的形狀也可減小，因此，可以大大減 15200415304 发明 Description of the invention: [Technical field to which the

Thus, the size of the rubber sheet 16 is large, and the cost of parts cannot be reduced. That is, since the size of the rubber plate 16 is large, the mold of the rubber plate 16 is expensive, and at the same time, the material cost is increased. In particular, in the case of using gasoline fuel containing alcohol as a fuel, a fluorine-containing rubber material is used, so that the material cost is greatly increased. In addition, since the fuel sprayed from the opening 1 2 D a of the vapor discharge hole 1 2 D directly conflicts with the bottom portion 16 B a of the concave portion 16 B of the rubber plate 16 and promotes the deterioration of the rubber quality, this is not good. . In addition, since the size of the rubber plate 16 is large, the shape of the bottom plate 1 1 A on the side supporting the rubber plate 16 is also large, so that the weight of the support bracket 11 is increased. The present invention has been made in consideration of the above-mentioned problems, and an object thereof is to provide a function of absorbing vibrations of an electric fuel pump and a support bracket, and a function of changing a flow direction of a vapor-containing fuel discharged from a vapor discharge hole to a side.

A thick portion; and a flange extending from the upper end of the fuel flow path thickened portion to the side, and a filter mounting hole and a steam exhaust hole facing the face portion provided on the flange, The fuel flow path thickened portion is inserted into the fuel intake passage of the electric fuel fruit. 'The filter mounting hole is inserted into the supporting thickened portion protruding downward from the pump bottom. The opposite side of the steam exhaust hole is arranged opposite to the opening of the steam exhaust hole, and the push nut is fitted into the supporting thickened portion protruding from the filter mounting hole of the flange, so that the filter is mounted on the electric fuel pump. On the other hand, the base plate of the support bracket is provided with an insulator mounting hole. At the same time, a cylindrical insulator made of an elastic material is inserted and arranged in the insulator mounting hole, and the insulator is arranged on the base plate of the support bracket and the electric fuel. Pump between the pump bottom.

In addition, since the vapor exhaust hole facing surface provided on the filter flange is arranged opposite to the opening of the vapor exhaust hole, the vapor-containing fuel discharged from the opening of the vapor exhaust hole collides with the vapor exhaust hole facing surface, and the flow direction can be directed toward The side changes. In addition, since the function of changing the flow direction of the steam-containing fuel discharged from the opening of the steam exhaust hole to the side is provided on the opposite side of the steam exhaust hole of the filter, it can be placed on the bottom of the pump and the support of the electric fuel pump. The shape of the insulator made of rubber material between the brackets is reduced, and the size of the bottom plate of the supporting bracket corresponding to the other end of the insulator can also be reduced. [Embodiment] An embodiment of a fuel supply device for a vehicle according to the present invention will be described below with reference to Figs. 1 and 2. Fig. 1 is a longitudinal sectional view of a main part near the bottom of an electric fuel pump mounted on a support bracket, and Fig. 2 is a cross-sectional view taken along a line C_C in Fig. 1. Since the electric fuel pump P has the same structure as before, the same reference numerals are used and the description is omitted. The filter F has a fuel flow path thickening portion 1 inserted in the fuel intake passage 1 2 C; a lower end of the fuel flow path thickening portion 1 has a filter · section for passing fuel (not shown in the fuel flow path) The upper end of the thickened portion 1 has a flat-shaped flange 1 A. The flange 1 A has a filter mounting hole 1 B and a vapor exhaust hole facing 12 312 / Instruction Manual (Supplement) / 92-09 / 92117245 200415304 Face 1 C, the filter mounting hole 1 B penetrates the flange 1 A, so this mounting hole can be inserted into the supporting thickened portion 15 protruding from the pump bottom 1 2 C. In addition, the steam exhaust hole can be closed with respect to the face 1 C The shape of the U-shaped partition wall 14 is opened below. The opening of the partition wall is downward from the pump bottom 12E. Element symbol 2 is a cylindrical insulator made of rubber material, which is composed of a large-diameter portion 2 A and The small-diameter portion 2 B is formed. The large-diameter portion 2 A is shaped to partially face the pump bottom 1 2 E, which can be cylindrical or prismatic, and the small-diameter portion 2B is cylindrical. For example, the large-diameter portion 2A The diameter is 10mm, and the diameter of the small-diameter part 2B is 4mm. (However, it is not limited This value). The upper end of the support bracket 3 is fixed to the cover 10 shown in the figure, and the lower end is bent to the side to form the bottom plate 3A. The bottom plate 3 A is made into a fork shape, and the insulator 2 faces the pump bottom 1 of the electric fuel pump P 2 E is partially arranged. On the bottom plate, two insulator mounting holes 3B are penetrated. The filter F is mounted on the electric fuel pump P as follows. The fuel flow path thickening part 1 of the filter F is inserted and arranged for fuel intake. In the passage 1 2 C, the upper surface of the flange 1 A of the filter F abuts on the anchoring step portion 1 2 C a disposed on the fuel flow path thickening portion 1 and the anchoring step portion supporting the thickening portion 15. 1 5 A. In this abutment state of the flange 1 A, the supporting thickened portion 15 is inserted and arranged in the filter mounting hole 1 B, and the vapor exhaust hole faces the surface 1 C and is closed from the bottom of the pump 1 2 E The lower part of the partition wall 14 protruding downwards is opened. The vapor exhaust hole is opposite to the surface 1 C, and the opening is inside the partition wall 14 13 312 / Invention Specification (Supplement) / 92-09 / 92117245 200415304 Vapor exhaust hole 1 The 2 D openings 1 2 D a are oppositely arranged. In addition, the push nut 18 is fitted and arranged at Through the flange 1 A and the supporting thickened portion 15 protruding downward, the filter F can be mounted toward the pump bottom 12E of the electric fuel pump P. In addition, the insulator 2 is arranged on the bottom plate 3A of the support bracket 3 Therefore, the two small-diameter portions 2B of each insulator 2 are inserted into and arranged in the respective insulator mounting holes 3 B passing through the bottom plate 3 A, so that the insulators 2 (specifically, the large-diameter portion 2 A) can be supported respectively. 3 A on each floor. The electric fuel pump P with the filter F mounted thereon is mounted on the support bracket 3, and the pump bottom 12E of the electric fuel pump P is disposed facing the bottom plate 3A. In this state, the filter F can be fixed to the support bracket 3 by using the fastening band 1 2 F shown in FIG. 3. In this fixed state, the upper surface of the large-diameter portion 2A of the insulator 2 is arranged close to the pump bottom 1 2 E, or it is placed on top of the pump bottom 1 2 E. With the fuel supply device of the present invention configured as described above, the electric fuel pump P can be driven, and the foreign matter in the fuel in the fuel tank T is removed by the filter portion of the filter F. This fuel passes through the fuel flow path thickening portion 1 inside The fuel intake passage 12C is sucked into the pump chamber 12A. In the pump chamber 12A, the fuel having the increased pressure is supplied to the engine through the fuel output passage 12G, the primary filter S, and the output pipe 13. At this time, the vapor generated in the pump chamber 12A is ejected downward from the opening 12D of the vapor discharge hole 12D together with the fuel. The fuel containing vapor, after colliding with the opposing surface 1 C of the vapor exhaust hole of the filter F, changes the flow direction to the outside and opens from the partition wall 14 opening to the left 1 4 A, 14 312 / Invention Specification (Supplement Pieces) / 92-09 / 92117245 200415304 Discharge to the left. Therefore, the pressurized fuel containing vapor does not collide with the filtering portion disposed at the lower end of the fuel flow path thickening portion 1 of the filter F, and does not damage or deform the filtering portion. On the other hand, during the operation of the engine, the electric fuel pump P and the support bracket 3 vibrate, and the vibration in the longitudinal direction of the electric fuel pump P can be absorbed by the insulator 2. Above, there are the following points worth noting. That is, since the flange 1 A of the filter F has the filter mounting hole 1 B and the vapor exhaust hole facing surface 1 C, the function of installing the filter F on the electric fuel pump P can be obtained, and the content of the filter F can be changed. The function of vapor fuel flow direction. In addition, since the flange 1 A having the filter mounting hole 1 B and the vapor exhaust hole facing portion 1 C is formed by using the synthetic resin material as a whole when forming the filter F, the manufacturing cost of the filter F will not increase. . Further, as described above, by providing the filter F with a function of changing the flow direction of the vapor, the insulator 2 only needs to have a vibration-proof function. In this way, the insulator 2 can be formed in a shape that partially comes into contact with the pump bottom 12 E, and therefore, the size of the insulator 2 can be greatly reduced. Therefore, even when the insulator 2 is manufactured using an expensive rubber material, since the amount of the material used is small, the manufacturing cost of the insulator 2 does not increase significantly. In addition, since the size of the insulator 2 is reduced, the shape of the bottom plate 3 A of the support bracket 3 that supports the insulator 2 can also be reduced, so that it can be greatly reduced.
