10圖其所繪示係日本專利公報特開平第9412374號所揭 露燃料箱裝置之構成說明圖。 第10圖所繪示之裝置係,將燃料泵71、燃料過濾器 72與調壓器73放置在,其形成係可上下分割爲二之基本 單元74。基本單元74係,通過燃料箱75之開口部份75a 被裝設於箱內,藉此,可將燃料泵71等裝設於燃料箱75 內。燃料箱75內載置固定有,構成輔助箱之容器部件76。 基本單兀74被配設於容器部件76內。而且,基本單元74 內設置有燃料通路77。藉燃料泵71吸上之燃料,通過燃 料通路77到達燃料過濾、器72或調壓器73,被自連接管78 供給至引擎。 然而,如第10其所繪示之燃料供給裝置,雖可改善 燃料泵71等組件化之作業性,但存在著組件全體容易大 型化之問題。特別是,因容器部件76而含輔助箱之構成, 變得非常大,由相對之燃料箱整體之大型化與小型輕量化 之觀點來看,有改善之需要。 4 本纸張尺度適用中國國家標準(CNS)A4規格(210 X 297公釐) Γ----一丨----------訂---------線 (請先閱讀背面之注意事項再填寫本頁) 經濟部智慧財產局員工消費合作社印製 經濟部智慧財產局員工消費合作社印製 493038 A7 6094pif.doc/008 〇7 五、發明說明(?) 另外,內槽式裝置中’爲了過濾濾器內部自泵吐出之 燃料,放置有濾紙或合成樹脂等過濾部件。但是,燃料通 過濾紙等時,容易因燃料與濾紙之接觸而發生靜電。而且, 過濾器前後之燃料也會成爲亂流,因合成樹脂箱與燃料之 接觸而帶靜電。 此時,因爲必須防止產生帶電狀態,而有如日本專利 公報特開平第8-232792號所揭露之內槽式燃料栗,於燃料 過爐器連接接地用引線將所產生之靜電接地之方法。於 此,箱內各部件皆連接著引線。然後,使引線電氣導通於 車輛束線除去各部件之接地,而防止部件之帶電。 而且,日本專利公報特開平第10-220315號中揭露, 將過爐器*自本身形成爲導電性材料1自其外周面箱燃料中 發放靜電之方法。除此之外上述公報中並揭露有,與導電 性過濾器箱連接引線,若箱外之接地電極或箱係金屬製 時,將此直接連接於箱而放掉靜電之構造。 然而,爲使當燃料箱內之燃料殘餘減少時可聯絡:丨喿作 貝’常設置使用熱敏電阻之燃料剩餘警τρς用感_

然而,燃料泵內已存在著濾器防止帶電用導線或馬達 供電用導線等。於此狀態若再加上熱敏電阻導線,則稍加 整理負導線,也無法避免導線數之增加。因此,隨著熱敏 電阻之設置,將增加導線作業或部件數,而形成增加成本 之問題要因。 發明之槪, 本發明的目的就是在提供一種可節省多餘空間之小型 燃料供給裝置。 而且本發明的另一目的就是在,於燃料供給裝置減少 導線作業或部件數使其構成簡素化。 爲了達成上述目的,本發明之燃料供給裝置係具備一 燃料泵用以吸入並吐出燃料箱內之燃料,及一濾器用以過 濾被自前述燃料泵吐出之燃料,及一調壓器用以調整前述 燃料之供給壓,於前述燃料箱內,配置有燃料泵,及至少 前述濾器與前述調壓器之任一的燃料供給裝置,並具有一 筒狀儲存箱’其被配設於前述燃料箱內,內部有一用以儲 存被吸入前述燃料泵之燃料的空間;一電極支架,被裝設

Description of the invention ((v) ^ When the front side of the car body is tilted up or stands up, the auxiliary box 16 The fuel flows out of the fuel input port 17 and does not violate the meaning of the auxiliary tank 16 to supply the engine with fuel stably for a long time. However, it is determined here by considering the two states when the front side of the vehicle body is tilted upwards and when it stands up. The opening position may be determined only by paying attention to any one of the elements. At this time, if it is important to raise upwards, it is on the front side of the vehicle body. If it is important to stand, the fuel inlet port Π may be opened in a direction opposite to the standing setting. The inside of the fuel inlet 17 has a labyrinth seal structure. That is, as shown in Figs. 7 and 8, the fuel inlet 17 is provided with a partition wall 18 extending from the opening portion 17a in the peripheral direction to the inside of the basic unit 4. As shown in Figs. The partition wall 18 and the inner wall of the base unit 4 form a labyrinth seal 19. This makes it difficult for the labyrinth seal 19 to flow out of the tank once the fuel flows into the auxiliary tank 16. Therefore, in the device 1, the position of the fuel inlet 17 is also different, and the fuel outflow from the auxiliary tank 16 can be reduced. In addition, the base unit 4 is provided with a thermistor 24 which changes its resistance 因 due to a temperature change, and is used as a fuel remaining warning sensor. Generally, the temperature in the fuel tank 2 has a tendency to rise as the fuel 42 decreases, and the thermistor 24 can detect this temperature change to capture the decrease in the amount of remaining fuel. The operator can then be contacted when the fuel 42 is reduced to bring the operator's attention. Fig. 9 is a diagram illustrating a state in which the thermistor 24 and a lead wire are installed.
