Description

この発明は、車両の燃料タンクの中に燃料ポンプを浸漬装着して、タンク内の燃料をエンジンに供給する燃料供給装置において、特に、燃料タンク内の燃料が極めて少量になるまで有効に供給できるようにするためのサブタンクを備えた燃料供給装置に関するものである。   The present invention is a fuel supply apparatus in which a fuel pump is immersed in a fuel tank of a vehicle and supplies the fuel in the tank to the engine. In particular, the fuel can be effectively supplied until the fuel in the fuel tank becomes very small. It is related with the fuel supply apparatus provided with the subtank for doing so.

従来の車両用燃料供給装置において、燃料タンクの中に燃料ポンプを浸漬した状態でタンク内の燃料をエンジンに供給する燃料供給装置がある。この種の燃料供給装置においては、燃料タンクの中に小形のサブタンクを設け、このサブタンクの中に燃料ポンプを設置することにより、燃料が少なくなった状態で車両が傾斜しても、または、急加減速などにより燃料液面が傾いても、サブタンクに燃料が残るように構成することにより燃料の供給が継続できるようになされた手段が知られている。（例えば、特許文献１第１図参照。）。   2. Description of the Related Art Conventional vehicle fuel supply apparatuses include a fuel supply apparatus that supplies fuel in a tank to an engine with a fuel pump immersed in the fuel tank. In this type of fuel supply device, a small sub-tank is provided in the fuel tank, and a fuel pump is installed in the sub-tank, so that even if the vehicle leans in a state where fuel is low, or suddenly There has been known a means that allows the fuel supply to be continued by configuring so that the fuel remains in the sub-tank even when the fuel level is inclined due to acceleration or deceleration. (For example, refer to FIG. 1 of Patent Document 1).

特許第２５５６０９７号公報Japanese Patent No. 2556097

上記のような車両用燃料供給装置においては、サブタンクを設けることにより、燃料が少なくなった状態で車両が傾斜しても、または、燃料液面が傾いても、サブタンクに燃料が残るようになされている。しかし、燃料タンク内におけるサブタンクの位置によっては、車両の傾斜方向次第でサブタンクに残る燃料が少なくなってしまう。また、燃料タンク内におけるサブタンクの位置が適切な位置に設けられていても、車両が大きく傾斜した場合にはサブタンクに残る燃料が少なくなって燃料供給に支障を生じる。   In the vehicular fuel supply apparatus as described above, the sub tank is provided so that the fuel remains in the sub tank even when the vehicle is inclined or the fuel level is inclined even when the fuel is low. ing. However, depending on the position of the subtank in the fuel tank, the amount of fuel remaining in the subtank decreases depending on the vehicle tilt direction. Even if the position of the sub tank in the fuel tank is set at an appropriate position, when the vehicle is largely inclined, the amount of fuel remaining in the sub tank is reduced and the fuel supply is hindered.

この発明は、上記のような課題を解決するためになされたもので、燃料の残量が少なくなった状態において、車両が傾斜するなど姿勢が変化した状態においても、または、急加減速などにより燃料液面が傾いても、通常の燃料供給がなされて燃料を有効に利用できる燃料供給装置を得ることを目的としている。   The present invention has been made to solve the above-described problems. Even when the remaining amount of fuel is low, the vehicle is tilted, or the posture is changed, or sudden acceleration / deceleration is performed. An object of the present invention is to obtain a fuel supply apparatus that can use fuel normally by supplying normal fuel even when the fuel level is inclined.

この発明は上記目的を達成するために、熱可塑性合成樹脂で形成されたサブタンクとこのサブタンクの中に固定された燃料ポンプを有し、このサブタンクを車両の燃料タンク内に装着して、燃料タンク内からサブタンクに流入した燃料を上記燃料ポンプによりエンジンに給送するようになされた燃料供給装置において、サブタンクの下端部に、発泡材あるいは不織布などによる濾過材が充填され、かつ、燃料流入口を有する濾過室を固定し、この濾過室に燃料ポンプの吸入口を結合して構成されたものである。   In order to achieve the above object, the present invention has a sub-tank formed of a thermoplastic synthetic resin and a fuel pump fixed in the sub-tank. The sub-tank is mounted in a fuel tank of a vehicle, and the fuel tank In the fuel supply device configured to feed the fuel flowing into the sub tank from the inside to the engine by the fuel pump, the lower tank is filled with a filtering material such as a foam material or a non-woven fabric at the lower end of the sub tank, and the fuel inlet is provided. The filter chamber is fixed, and the suction port of the fuel pump is connected to the filter chamber.

また、濾過室は、サブタンクの下側に、上記サブタンクと同様の材料で形成された濾過室タンクを熱溶着して形成したものである。   The filtration chamber is formed by thermally welding a filtration chamber tank made of the same material as that of the sub tank below the sub tank.

上述したようにこの発明の燃料供給装置は、サブタンクの下端部に、発泡材あるいは不織布などによる濾過材が充填され、かつ、燃料流入口を有する濾過室を固定した。この濾過室は、常時毛細管作用により燃料が充満している。この濾過室に燃料ポンプの吸入口を結合して構成したので、車両が傾斜するなど姿勢が変化した状態においても、通常の燃料供給が継続できる。   As described above, in the fuel supply device of the present invention, the lower tank is filled with a filtering material such as a foamed material or a non-woven fabric at the lower end portion, and a filtering chamber having a fuel inlet is fixed. This filtration chamber is always filled with fuel by capillary action. Since the suction port of the fuel pump is connected to the filtration chamber, normal fuel supply can be continued even in a state where the posture is changed, for example, the vehicle is inclined.

また、濾過室は、サブタンクの下側に、サブタンクと同様の材料で形成された濾過室タンクを熱溶着して形成し、この濾過室に燃料ポンプの吸入口を結合して構成したので、部品数が少なく構成が簡単で、燃料ポンプの設置状態も安定した状態になる。   The filtration chamber is formed by thermally welding a filtration chamber tank made of the same material as the sub tank below the sub tank, and the suction port of the fuel pump is connected to the filtration chamber. The number is small and the configuration is simple, and the installation state of the fuel pump is also stable.

以下、この発明の実施の形態を図１ないし図４に基づいて説明する。図１は燃料供給装置の使用状態を示す断面図であり、図において、５０は車両に設置された燃料タンクであり、天井面に開口部５０ａが設けられている。この開口部５０ａはパッキン５１を有する蓋５２がねじにより取付けられている。なお、図示を省略しているが、開口部５０ａの周縁部には、後述の燃料供給装置１００を燃料タンク内に装着するための取付け部、燃料供給装置１００からエンジンに燃料を給送するための給送管５３、燃料供給装置１００をバッテリーに接続する電線、あるいは、燃料の量を表示するための信号線などの通路が設けてある。
なお、燃料供給装置１００は、説明の都合上、燃料タンク５０及び蓋５２などに比較して大きく図示されている。 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a cross-sectional view showing a fuel supply device in use. In FIG. 1, reference numeral 50 denotes a fuel tank installed in a vehicle, and an opening 50a is provided on the ceiling surface. A lid 52 having a packing 51 is attached to the opening 50a with a screw. Although not shown in the drawings, a peripheral portion of the opening 50a is provided with a mounting portion for mounting a fuel supply device 100, which will be described later, in the fuel tank, and for supplying fuel from the fuel supply device 100 to the engine. A passage such as a feed pipe 53, an electric wire for connecting the fuel supply device 100 to the battery, or a signal line for displaying the amount of fuel is provided.
For convenience of explanation, the fuel supply device 100 is shown larger than the fuel tank 50, the lid 52, and the like.

燃料供給装置１００は、燃料ポンプ１０と、サブタンク２０と、濾過材３０などを備えている。燃料ポンプ１０は、車両のバッテリーを電源にした電動機により回転駆動されるウエスコ形ポンプであり、１１は吸入口、１２は吐出口である。サブタンク２０は、耐ガソリン性の熱可塑性合成樹脂（例えばポリアセタール樹脂）で底がある筒状に形成され、内部に燃料ポンプ１０が設置できる程度に小形に形成されたものである。２１は濾過室タンクであり、サブタンク２０と同様の熱可塑性合成樹脂で形成され、サブタンク２０の下側に熱溶着して設けられている。熱溶着は、超音波法あるいは振動法などによりなされる。この濾過室タンク２１の熱溶着により濾過室２２が形成されている。２０ｂは熱溶着された溶着部を示す。濾過室２２の上面には燃料ポンプ１０の吸入口１１を結合するための結合口２０ａが設けてある。サブタンク２０の側面には、１箇所ないし複数箇所に逆止弁２３が設けてあり、燃料タンク５０からサブタンク２０に流入した燃料が燃料タンク５０に逆流しないようになされている。   The fuel supply apparatus 100 includes a fuel pump 10, a sub tank 20, a filter medium 30, and the like. The fuel pump 10 is a Wesco-type pump that is rotationally driven by an electric motor that uses a vehicle battery as a power source. Reference numeral 11 denotes a suction port, and 12 denotes a discharge port. The sub tank 20 is formed in a cylindrical shape with a bottom made of a gasoline-resistant thermoplastic synthetic resin (for example, polyacetal resin), and is small enough to install the fuel pump 10 therein. Reference numeral 21 denotes a filtration chamber tank, which is formed of the same thermoplastic synthetic resin as that of the sub tank 20 and is thermally welded to the lower side of the sub tank 20. The thermal welding is performed by an ultrasonic method or a vibration method. A filtration chamber 22 is formed by heat welding of the filtration chamber tank 21. Reference numeral 20b denotes a welded portion that has been thermally welded. A coupling port 20 a for coupling the suction port 11 of the fuel pump 10 is provided on the upper surface of the filtration chamber 22. A check valve 23 is provided at one or a plurality of locations on the side surface of the sub tank 20 so that the fuel flowing into the sub tank 20 from the fuel tank 50 does not flow back into the fuel tank 50.

燃料ポンプ１０は、サブタンク２０の結合口２０ａに吸入口１１が結合された状態で、
サブタンク２０の中に保持され、吐出口１２には給送管５３が接続されている。燃料ポンプ１０が保持されたサブタンク２０の上端にはブラケット２４が設けてあり、燃料タンク５０の開口部５０ａに装着されている。給送管５３、燃料供給装置１００をバッテリーに接続する電線、あるいは、燃料の量を表示するための信号線などは、上記のように開口部５０ａの周縁部の通路を通して所定の機構に接続されている。なお、濾過室２２に燃料が流入するように、濾過室タンク２１などに燃料流入孔２２ａが設けてある。Ｆａは燃料タンク５０の中の燃料を示す。Ｆｂはサブタンク２０の中に流入した燃料を示す。 The fuel pump 10 is in a state where the suction port 11 is coupled to the coupling port 20a of the sub tank 20,
A feed pipe 53 is connected to the discharge port 12 while being held in the sub tank 20. A bracket 24 is provided at the upper end of the sub-tank 20 that holds the fuel pump 10, and is attached to the opening 50 a of the fuel tank 50. The feed pipe 53, the electric wire connecting the fuel supply device 100 to the battery, or the signal line for displaying the amount of fuel are connected to a predetermined mechanism through the passage at the peripheral edge of the opening 50a as described above. ing. A fuel inflow hole 22 a is provided in the filtration chamber tank 21 so that the fuel flows into the filtration chamber 22. Fa indicates the fuel in the fuel tank 50. Fb indicates the fuel that has flowed into the sub tank 20.

この濾過室２２には濾過材３０が充填されている。濾過材３０は、図２に示すように、
濾過室２２の形状に合わせて発泡材で形成されている。発泡材は、耐ガソリン性の合成樹脂材を用いて連通気泡のスポンジ状に加工したものである。なお、濾過材３０は、耐ガソリン性の合成樹脂繊維を用いた不織布を積層して形成したものであってもよい。この、濾過材３０の充填は、濾過室タンク２１をサブタンク２０に熱溶着する際になされる。 The filter chamber 22 is filled with a filter medium 30. As shown in FIG.
It is made of a foam material in accordance with the shape of the filtration chamber 22. The foamed material is processed into a sponge with open cells using a gasoline-resistant synthetic resin material. The filter medium 30 may be formed by laminating nonwoven fabrics using gasoline-resistant synthetic resin fibers. This filling of the filter medium 30 is performed when the filtration chamber tank 21 is thermally welded to the sub tank 20.

濾過材３０として、不織布を積層して形成するものは、通常、数種類の形状の不織布の小片を多数積層することになる。この積層を、サブタンク２０または濾過室タンク２１の
いずれかに（または両方に）充填状態に積層して、その状態でサブタンク２０と濾過室タンク２１を熱溶着することは、充填状態に積層する作業及び熱溶着共に作業性が悪い。この発明の実施の形態では、この点について、あらかじめ、所定の形状に形成された不織布製のカップの中に、不織布の小片を充填状態に積層して構成された濾過材３０を準備しておく。換言すれば、不織布の小片を多数積層したものの外周を、包被用の不織布で包被して濾過材３０を構成するものである。この構成としては、例えば図３に示すように、厚さが薄い不織布で上カップ３０ａと下カップ３０ｂを形成しておき、これに不織布の小片を積層状態に詰め込んで上カップ３０ａと下カップ３０ｂを仮止めして濾過材３０を構成する。この場合、上カップ３０ａと下カップ３０ｂは濾過室２２の内周に沿う形のカップ状に形成されたものである。このようにして構成された濾過材３０は、濾過材３０の構成が容易で、濾過室２２に対する充填も簡単であり、濾過室タンク２１とサブタンク２０の熱溶着の作業性にも優れている。なお、不織布の小片のかわりに、前記の発泡材を小片にして充填してもよい。 As the filter medium 30, what is formed by laminating non-woven fabrics usually involves laminating a large number of small pieces of non-woven fabric of several types. This lamination is laminated in either the sub tank 20 or the filtration chamber tank 21 (or both) in a filled state, and the sub tank 20 and the filtration chamber tank 21 are thermally welded in that state. In addition, both workability and heat welding are poor. In the embodiment of the present invention, in this regard, a filtering material 30 is prepared in advance, which is configured by laminating pieces of nonwoven fabric in a packed state in a nonwoven fabric cup formed in a predetermined shape. . In other words, the filter medium 30 is configured by covering the outer periphery of a stack of a large number of pieces of nonwoven fabric with the nonwoven fabric for covering. For example, as shown in FIG. 3, the upper cup 30a and the lower cup 30b are formed of a thin nonwoven fabric, and small pieces of the nonwoven fabric are packed in a laminated state to form the upper cup 30a and the lower cup 30b. Is temporarily fixed to constitute the filter medium 30. In this case, the upper cup 30 a and the lower cup 30 b are formed in a cup shape along the inner periphery of the filtration chamber 22. The filter medium 30 configured in this way is easy to configure the filter medium 30, easily fills the filter chamber 22, and has excellent workability in heat welding between the filter chamber tank 21 and the sub tank 20. Instead of the non-woven fabric pieces, the foam material may be filled as small pieces.

なお、上カップ３０ａと下カップ３０ｂについては、図３に示すように、上カップ３０ａにフランジ部３０ｃを設け、下カップ３０ｂにフランジ部３０ｄを設けて、濾過室タンク２１を熱溶着する際に、このフランジ部３０ｃとフランジ部３０ｄを介して熱溶着する構成も考えられる。このように、上カップ３０ａと下カップ３０ｂを用いて濾過材３０を構成したものは、濾過室２２を構成するための部品数が少なく加工も容易になる。   In addition, about the upper cup 30a and the lower cup 30b, as shown in FIG. 3, when the flange part 30c is provided in the upper cup 30a, the flange part 30d is provided in the lower cup 30b, and the filtration chamber tank 21 is heat-welded. A configuration in which heat welding is performed through the flange portion 30c and the flange portion 30d is also conceivable. Thus, what comprised the filter medium 30 using the upper cup 30a and the lower cup 30b has few components for comprising the filtration chamber 22, and also becomes easy to process.

このように構成された燃料供給装置１００によれば、燃料タンク５０の中の燃料Ｆａが少なくなった状態で、図４に示すように傾斜しても、濾過室２２の中の濾過材３０は、毛細管作用により燃料を吸い込んだ状態を維持し、濾過室２２の外に流出することがない。従って、従来の燃料供給装置で、車両が傾斜すると、燃料フィルタから燃料が流出して燃料が供給できなくなる場合でも、この発明のものでは燃料を有効利用できる。   According to the fuel supply device 100 configured as described above, even when the fuel Fa in the fuel tank 50 is reduced and the vehicle is inclined as shown in FIG. The state in which the fuel is sucked in by the capillary action is maintained and does not flow out of the filtration chamber 22. Therefore, with the conventional fuel supply device, even when the vehicle tilts and the fuel flows out from the fuel filter and cannot be supplied, the fuel can be used effectively in the present invention.
