Description

本発明は、燃料供給装置、特に燃料タンク外に露出する燃料出口管を有して燃料タンクの開口部を閉塞する蓋と、軸方向一方側に吸入部を、他方側に吐出部をそれぞれ有する燃料ポンプと、蓋に支持されて燃料タンク内に延び且つ燃料ポンプを保持する筐体とを備え、筐体が、吐出部及び燃料出口管間を連通させる連通路を有し、蓋が、蓋による開口部の閉塞状態で、開口部の周縁部に対し平行で且つ液密に接触する閉塞面を有する車両用燃料供給装置に関する。 The present invention has a fuel supply device, particularly a lid having a fuel outlet pipe exposed to the outside of the fuel tank to close the opening of the fuel tank, an suction portion on one side in the axial direction, and a discharge portion on the other side. It comprises a fuel pump and a housing that is supported by a lid and extends into the fuel tank and holds the fuel pump. The housing has a communication passage for communicating between a discharge portion and a fuel outlet pipe, and the lid is a lid. The present invention relates to a fuel supply device for a vehicle having a closed surface that is parallel to the peripheral edge of the opening and is in liquid-tight contact with the peripheral portion of the opening in a closed state of the opening.

上記した燃料供給装置は、例えば特許文献１に開示されるように従来公知であり、このものの燃料ポンプは、これの軸線が蓋の上記閉塞面と略平行となるよう上記筐体に保持され、これにより、軸線方向に長い燃料ポンプ（従って筐体）を燃料タンク壁面に概ね沿わせて配置可能として、燃料タンクの比較的狭小な内部空間にも無理なくコンパクトに配備できるようにしている。 The above-mentioned fuel supply device is conventionally known as disclosed in, for example, Patent Document 1, and the fuel pump of the above-mentioned fuel pump is held in the above-mentioned housing so that the axis of the fuel pump thereof is substantially parallel to the above-mentioned closing surface of the lid. As a result, the fuel pump (hence, the housing) long in the axial direction can be arranged almost along the wall surface of the fuel tank, and can be deployed reasonably and compactly even in the relatively narrow internal space of the fuel tank.

特開２０１９−１９７２２号公報Japanese Unexamined Patent Publication No. 2019-19722

特許文献１の燃料供給装置では、筐体に設けられてポンプ吐出部と蓋の燃料出口管との間を連通させる連通路が、蓋の水平な閉塞面（従って閉塞面が液密に接触する、開口部周辺のタンクの水平な底壁部）に対し直角方向、即ち鉛直方向に長く延出している。 In the fuel supply device of Patent Document 1, the communication passage provided in the housing and communicating between the pump discharge portion and the fuel outlet pipe of the lid is in contact with the horizontal closing surface of the lid (hence, the closing surface is liquidtight). , The horizontal bottom wall of the tank around the opening) extends in the direction perpendicular to it, that is, in the vertical direction.

そのため、斯かる連通路構造を仮に、タンク底壁部が水平面に対し傾斜した燃料タンクにそのまま適用した場合（例えば図５を参照）には、上記連通路が蓋の傾斜した閉塞面に対し斜め上方に長く延出する配置となり、これに伴い、蓋中心を通る鉛直面に対し傾倒した燃料供給装置の上端部が、蓋から横方向に少なからず張出してしまう。従って、その横方向に張出した燃料供給装置の上端部を避けるために、燃料タンクの対応する外側壁を外側方に張出させる必要があり、それだけ燃料タンクが大型化する不都合がある。 Therefore, if such a communication passage structure is applied as it is to a fuel tank in which the tank bottom wall portion is inclined with respect to the horizontal plane (see, for example, FIG. 5), the communication passage is oblique with respect to the inclined closed surface of the lid. The arrangement is such that it extends upward for a long time, and as a result, the upper end of the fuel supply device tilted with respect to the vertical plane passing through the center of the lid protrudes laterally from the lid to a considerable extent. Therefore, in order to avoid the upper end of the fuel supply device overhanging in the lateral direction, it is necessary to overhang the corresponding outer wall of the fuel tank outward, which is inconvenient for the fuel tank to become large.

本発明は、上記に鑑み提案されたもので、蓋の閉塞面が、蓋によるタンク開口部の閉塞状態で水平面に対し傾斜した配置となる燃料供給装置であっても、これの横方向への張出しが効果的に抑えられて燃料タンクの小型化に寄与することができる車両用燃料供給装置を提供することを目的としている。 The present invention has been proposed in view of the above, and even in a fuel supply device in which the closed surface of the lid is inclined with respect to the horizontal plane in a closed state of the tank opening by the lid, the closed surface of the fuel supply device is laterally arranged. An object of the present invention is to provide a fuel supply device for a vehicle, which can effectively suppress overhang and contribute to the miniaturization of a fuel tank.

上記目的を達成するために、本発明は、燃料タンク外に露出する燃料出口管を有して燃料タンクの開口部を閉塞する蓋と、軸方向一方側に吸入部を、他方側に吐出部をそれぞれ有する燃料ポンプと、前記蓋に支持されて燃料タンク内に延び且つ前記燃料ポンプを保持する筐体とを備え、前記筐体は、前記吐出部及び前記燃料出口管間を連通させる連通路を有し、前記蓋は、該蓋による前記開口部の閉塞状態で、該開口部の周縁部に対し平行で且つ液密に接触する閉塞面を有し、前記燃料ポンプは、これの軸線が前記閉塞面と略平行となるよう前記筐体に保持される車両用燃料供給装置において、前記閉塞面は、前記蓋による前記開口部の閉塞状態で、前記軸線と直交する投影面で見て水平面に対し傾斜するよう配置され、前記連通路は、前記投影面で見て、前記閉塞面と直交する基準線に対し該閉塞面の上端側に傾斜した傾斜通路部を有することを第１の特徴とする。 In order to achieve the above object, the present invention has a lid having a fuel outlet pipe exposed to the outside of the fuel tank to close the opening of the fuel tank, a suction portion on one side in the axial direction, and a discharge portion on the other side. Each of the fuel pumps is provided with a housing that is supported by the lid and extends into the fuel tank and holds the fuel pump, and the housing is a communication passage that communicates between the discharge portion and the fuel outlet pipe. The lid has a closed surface that is parallel to and in liquid-tight contact with the peripheral edge of the opening in a closed state of the opening by the lid, and the fuel pump has an axis thereof. In a vehicle fuel supply device held in the housing so as to be substantially parallel to the closed surface, the closed surface is a horizontal plane when viewed from a projection plane orthogonal to the axis in a closed state of the opening by the lid. The first feature is that the communication passage is arranged so as to be inclined with respect to the closed surface, and the continuous passage has an inclined passage portion inclined to the upper end side of the closed surface with respect to a reference line orthogonal to the closed surface when viewed from the projected surface. And.

また本発明は、第１の特徴に加えて、前記吸入部に接続されるフィルタを更に備え、前記燃料タンクは、少なくとも前記開口部の周辺で前記閉塞面と平行な底壁部、又は前記閉塞面と平行であって車両中央側を向く側壁部を有していて、該底壁部又は該側壁部に前記開口部が設けられており、前記フィルタは、前記投影面で見て前記軸線よりも前記閉塞面の下端側にオフセット配置されることを第２の特徴とする。 Further, in addition to the first feature, the present invention further includes a filter connected to the suction portion, and the fuel tank has a bottom wall portion parallel to the closing surface or the closing at least around the opening. It has a side wall that is parallel to the surface and faces the center of the vehicle, and the opening is provided in the bottom wall or the side wall, and the filter is from the axis when viewed from the projection surface. The second feature is that the fuel is offset on the lower end side of the closed surface.

また本発明は、第１又は第２の特徴に加えて、前記燃料ポンプの吐出油圧の上限を規制するプレッシャレギュレータが前記筐体に保持され、前記プレッシャレギュレータは、前記傾斜通路部を介して前記吐出部と接続されると共に、前記投影面で見て、該傾斜通路部の軸線方向で前記燃料ポンプの一方側又は他方側に配置されることを第３の特徴としている。 Further, in the present invention, in addition to the first or second feature, a pressure regulator that regulates the upper limit of the discharge oil pressure of the fuel pump is held in the housing, and the pressure regulator is said to be via the inclined passage portion. The third feature is that the fuel pump is connected to the discharge portion and is arranged on one side or the other side of the fuel pump in the axial direction of the inclined passage portion when viewed from the projection surface.

また本発明は、第１〜第３の何れかの特徴に加えて、前記蓋は、前記燃料ポンプへの給電に用いられ且つ前記燃料タンク外に張出す給電カプラを有し、前記燃料タンクは、車体の、車両中央を通って前後方向に延びるメインフレームを跨ぐ中間タンク部と、その中間タンク部の左右両側より一体に垂下する一対の側部タンク部とを有して概ね鞍状に形成され、何れか一方の前記側部タンク部の、外方下側に傾斜した底壁部又は車両中央側の側壁部に前記開口部が設けられることを第４の特徴とする。 Further, in the present invention, in addition to any of the first to third features, the lid has a power feeding coupler that is used for power supply to the fuel pump and extends out of the fuel tank, and the fuel tank has a power supply coupler. , The vehicle body has an intermediate tank portion that straddles the main frame extending in the front-rear direction through the center of the vehicle and a pair of side tank portions that hang integrally from the left and right sides of the intermediate tank portion, and is formed in a substantially saddle shape. The fourth feature is that the opening is provided in the bottom wall portion inclined outwardly downward or the side wall portion on the vehicle center side of any one of the side tank portions.

第１の特徴によれば、蓋の閉塞面が、燃料タンクの開口部の閉塞状態で、ポンプ軸線と直交する投影面で見て水平面に対し傾斜するよう配置され、筐体に設けられて燃料ポンプの吐出部と蓋の燃料出口管との間を連通させる連通路が、上記投影面で見て、閉塞面と直交する基準線に対し閉塞面の上端側に傾斜した傾斜通路部を有する。これにより、蓋の閉塞面が水平面に対し傾斜していても、この傾斜に伴う燃料供給装置の傾倒、即ち、蓋の位置を基準とした燃料供給装置の横方向の張出し（従って燃料タンクの同方向への張出し）が効果的に抑えられるため、燃料タンクを小型化する上で有利となり、また小型の燃料タンク内にも燃料供給装置を無理なく配備可能となる。 According to the first feature, the closed surface of the lid is arranged so as to be inclined with respect to the horizontal plane when viewed from the projection plane orthogonal to the pump axis in the closed state of the opening of the fuel tank, and is provided in the housing to provide fuel. The communication passage that communicates between the discharge portion of the pump and the fuel outlet pipe of the lid has an inclined passage portion that is inclined toward the upper end side of the closing surface with respect to the reference line orthogonal to the closing surface when viewed from the projection surface. As a result, even if the closed surface of the lid is inclined with respect to the horizontal plane, the fuel supply device is tilted due to this inclination, that is, the fuel supply device is laterally extended with reference to the position of the lid (thus, the same as the fuel tank). Since the overhang in the direction is effectively suppressed, it is advantageous in reducing the size of the fuel tank, and the fuel supply device can be easily deployed in the small fuel tank.

また第２の特徴によれば、燃料ポンプの吸入部に連なるフィルタは、ポンプ軸線と直交する投影面で見て、ポンプ軸線よりも閉塞面の下端側にオフセット配置されるので、燃料タンクの、下側に傾斜した底壁部又は側壁部の低位側にフィルタを偏位させることができる。これにより、タンク内の液量が少なくなった場合でも、燃料ポンプは、低位側に偏在するフィルターを通して燃料を吸引可能となる。 According to the second feature, the filter connected to the suction portion of the fuel pump is offset from the pump axis to the lower end side of the closed surface when viewed from the projection plane orthogonal to the pump axis. The filter can be displaced to the lower side of the bottom wall or side wall that is inclined downward. As a result, even when the amount of liquid in the tank becomes low, the fuel pump can suck fuel through the filters unevenly distributed on the lower side.

また第３の特徴によれば、筐体に保持したプレッシャレギュレータが、傾斜通路部を介して吐出部と接続されると共に、上記投影面で見て、傾斜通路部の軸線方向で燃料ポンプの一方側又は他方側に配置されるので、プレッシャレギュレータと燃料ポンプとが傾斜通路部の軸線方向に並ぶ配置となることで、それらを保持する筐体（従って燃料供給装置）の全高が高くなってしまう。しかし上記した第１の特徴に基づき燃料供給装置の傾倒すなわち横方向張出しが抑えられることから、燃料タンクを小型化した場合でも、全高の高い燃料供給装置を燃料タンク内に無理なく配備可能となる。 Further, according to the third feature, the pressure regulator held in the housing is connected to the discharge portion via the inclined passage portion, and is one of the fuel pumps in the axial direction of the inclined passage portion when viewed from the projection plane. Since it is arranged on the side or the other side, the pressure regulator and the fuel pump are arranged so as to be aligned in the axial direction of the inclined passage portion, so that the total height of the housing (hence, the fuel supply device) that holds them becomes high. .. However, since the tilting of the fuel supply device, that is, the lateral extension is suppressed based on the first feature described above, even if the fuel tank is miniaturized, the fuel supply device having a high overall height can be easily deployed in the fuel tank. ..

また第４の特徴によれば、蓋は、燃料タンク外に張出す給電カプラを有し、燃料タンクは、車体の車両中央を通るメインフレームを跨ぐ中間タンク部と、その中間タンク部の左右両側より一体に垂下する一対の側部タンク部とを有して鞍状に形成されると共に、一方の側部タンク部の、外方下側に傾斜した底壁部又は車両中央側の側壁部に開口部が設けられるので、その開口部を閉塞する蓋、及びそれから張出す燃料出口管や給電カプラが燃料タンクの外側壁で効果的に遮蔽される。これにより、それら蓋、燃料出口管及び給電カプラは、他物の衝突から有効に保護され、しかも燃料タンクにより体裁よく隠蔽されて製品の美観向上が図られる。 According to the fourth feature, the lid has a power supply coupler that extends out of the fuel tank, and the fuel tank has an intermediate tank portion that straddles the main frame passing through the center of the vehicle body and both left and right sides of the intermediate tank portion. It is formed in a saddle shape with a pair of side tank parts that hang down more integrally, and on one side tank part, on the bottom wall part that is inclined outward and downward or on the side wall part on the vehicle center side. Since the opening is provided, the lid that closes the opening and the fuel outlet pipe and power supply coupler that overhang from the opening are effectively shielded by the outer wall of the fuel tank. As a result, these lids, fuel outlet pipes, and power supply couplers are effectively protected from collisions with other objects, and are also aesthetically concealed by the fuel tank to improve the appearance of the product.

以下、本発明の実施の形態について、添付図面を参照しながら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

先ず、図１〜図４において、鞍乗り型車両、例えば自動二輪車に搭載される燃料タンクＴの底部には、燃料タンクＴ内の燃料を加圧して車載エンジンの燃料噴射弁に供給する燃料ポンプモジュールＦＭが取付けられる。 First, in FIGS. 1 to 4, a fuel pump that pressurizes the fuel in the fuel tank T and supplies it to the fuel injection valve of the in-vehicle engine at the bottom of the fuel tank T mounted on a saddle-riding vehicle, for example, a motorcycle. The module FM is installed.

車体適所に固定の燃料タンクＴは、本実施形態では車体の、車両中央を通って前後方向に水平又は後下りに延びるメインフレーム６を跨ぐ中間タンク部Ｔｍと、その中間タンク部Ｔｍの左右両側より一体に垂下する一対の側部タンク部Ｔｓ，Ｔｓ′とを有して概ね鞍状に形成される。即ち、燃料タンクＴの、メインフレーム６が通る車体空間に臨むタンク壁面は、横断面が逆Ｕ字状に形成される。 In the present embodiment, the fuel tank T fixed at an appropriate position on the vehicle body is an intermediate tank portion Tm straddling the main frame 6 extending horizontally or backward and downward in the front-rear direction through the center of the vehicle body, and both left and right sides of the intermediate tank portion Tm. It has a pair of side tank portions Ts and Ts' that hang down more integrally, and is formed in a substantially saddle shape. That is, the tank wall surface of the fuel tank T facing the vehicle body space through which the main frame 6 passes is formed in an inverted U shape in cross section.

左右一方の側部タンク部Ｔｓの底壁部１１には、前後方向に長い長円形に形成される開口部７が設けられ、その開口部７を塞ぐようにして燃料ポンプモジュールＦＭの蓋８が底壁部１１に取付けられる。底壁部１１は、燃料タンクＴの横断面で見て、水平面に対し外方下側に傾斜（より具体的に言えば、車両中央を前後方向に通る鉛直面を基準として外方下側に傾斜）している。 The bottom wall portion 11 of the left and right side tank portions Ts is provided with an opening 7 formed in an oval shape that is long in the front-rear direction, and the lid 8 of the fuel pump module FM closes the opening 7. It is attached to the bottom wall portion 11. The bottom wall portion 11 is inclined outward and downward with respect to the horizontal plane when viewed in the cross section of the fuel tank T (more specifically, outward and downward with respect to the vertical plane passing through the center of the vehicle in the front-rear direction). (Inclined).

他方の側部タンク部Ｔｓ′は、これの底壁部１１′の左右幅が狭く形成され、それに伴い、車両中央（従ってメインフレーム６）側を向く側壁部１２が、前記鉛直面を基準として外方下側に傾斜していて底壁部１１′まで延びている。尚、後述するように、傾斜した前記側壁部１２の下部に開口部７を設けて燃料ポンプモジュールＦＭを取付けるようにしてもよい。 The left and right width of the bottom wall portion 11'of the other side tank portion Ts'is formed to be narrow, and accordingly, the side wall portion 12 facing the vehicle center (and therefore the main frame 6) side is based on the vertical plane. It is inclined outward and downward and extends to the bottom wall portion 11'. As will be described later, the fuel pump module FM may be attached by providing an opening 7 at the lower portion of the inclined side wall portion 12.

この燃料ポンプモジュールＦＭは、底壁部１１に着脱可能に結合されて底壁部１１の開口部７を液密に閉塞する長円形状の蓋８と、蓋８に結合、支持されて燃料タンクＴ内に延びる筐体２０と、その筐体２０に収容、保持される電動式のポンプユニットＰと、ポンプユニットＰの吸込側に接続されるフィルタ４０と、筐体２０に設けられてポンプユニットＰの吐出油圧を所定の上限値以下に規制するプレッシャレギュレータＲとを備える。而して、燃料ポンプモジュールＦＭは、本発明の燃料供給装置の一例であり、またポンプユニットＰは、本発明の燃料ポンプの一例である。 The fuel pump module FM is detachably connected to the bottom wall portion 11 to form an oval lid 8 that liquidally closes the opening 7 of the bottom wall portion 11, and is coupled to and supported by the lid 8 to provide a fuel tank. A housing 20 extending in T, an electric pump unit P housed and held in the housing 20, a filter 40 connected to the suction side of the pump unit P, and a pump unit provided in the housing 20. It is provided with a pressure regulator R that regulates the discharge oil pressure of P to a predetermined upper limit or less. Thus, the fuel pump module FM is an example of the fuel supply device of the present invention, and the pump unit P is an example of the fuel pump of the present invention.

プレッシャレギュレータＲは、通常は閉弁状態に保持され、且つポンプユニットＰの吐出油圧が設定値を超えるとその圧力で開弁して吐出油の一部を燃料タンクＴ内に還流させるよう構成され、その機能は、従来周知のプレッシャレギュレータと同様である。 The pressure regulator R is normally held in a closed state, and when the discharge oil pressure of the pump unit P exceeds a set value, the pressure regulator R is configured to open the valve at that pressure and return a part of the discharged oil to the fuel tank T. , Its function is the same as that of a conventionally known pressure regulator.

ポンプユニットＰは、前記底壁部１１に略沿って車両前後方向に長く延びる円筒状のユニットケースＰｃと、そのユニットケースＰｃに内蔵される不図示のポンプ部と、同じくユニットケースＰｃに内蔵されてポンプ部を駆動する不図示のモータ部とを備える。ユニットケースＰｃは、これの軸方向一方側に燃料の吸入部Ｐｃｉを、他方側に燃料の吐出部Ｐｃｏをそれぞれ有しており、ポンプユニットＰの軸線Ｌｐは、開口部７周囲の底壁部１１（従って、蓋８の後述する閉塞面８０）と略平行に配置される。 The pump unit P is incorporated in a cylindrical unit case Pc that extends substantially along the bottom wall portion 11 in the front-rear direction of the vehicle, a pump portion (not shown) incorporated in the unit case Pc, and the unit case Pc. A motor unit (not shown) for driving the pump unit is provided. The unit case Pc has a fuel suction portion Pci on one side in the axial direction thereof and a fuel discharge portion Pco on the other side, and the axis Lp of the pump unit P is a bottom wall portion around the opening 7. It is arranged substantially parallel to 11 (hence, the closing surface 80 of the lid 8 described later).

蓋８は、前記底壁部１１の開口部７よりも大きく形成されて開口部７を外側から覆う平板状の蓋本体８ｍと、蓋本体８ｍに一体に突設されて開口部７を通して燃料タンクＴ（特に側部タンク部Ｔｓ）内に張出す取付台部８ｂとを備えていて、複数のボルト２４により底壁部１１に締結される。その各ボルト２４は、取付台部８ｂの周囲で蓋本体８ｍを貫通して、底壁部１１の内面に固定の袋ナット１１ｎに螺合される。 The lid 8 is formed to be larger than the opening 7 of the bottom wall portion 11 and has a flat plate-shaped lid body 8 m that covers the opening 7 from the outside, and a fuel tank that is integrally projected from the lid body 8 m and passes through the opening 7. It is provided with a mounting base portion 8b that projects into the T (particularly the side tank portion Ts), and is fastened to the bottom wall portion 11 by a plurality of bolts 24. Each of the bolts 24 penetrates the lid body 8 m around the mounting base portion 8b and is screwed into the bag nut 11n fixed to the inner surface of the bottom wall portion 11.

取付台部８ｂの周囲で蓋本体８ｍの裏面は、蓋８による開口部７の閉塞状態で開口部７の周縁部に対し平行であり且つシール部材２５を介し液密に接触するものであって、本発明の閉塞面８０を構成する。そして、前記閉塞状態で閉塞面８０は、前述の底壁部１１と同様、ポンプユニットＰの軸線Ｌｐと直交する投影面（図２，図４参照）で見て、水平面に対し外方下側に傾斜した配置となる。 The back surface of the lid body 8 m around the mounting base portion 8b is parallel to the peripheral edge portion of the opening 7 in a closed state by the lid 8, and is in liquid-tight contact with the seal member 25. , Consists of the closed surface 80 of the present invention. Then, in the closed state, the closed surface 80 is outwardly lower side with respect to the horizontal plane when viewed from the projection plane (see FIGS. 2 and 4) orthogonal to the axis Lp of the pump unit P, similarly to the bottom wall portion 11 described above. The layout is inclined to.

上記シール部材２５は、閉塞面８０に凹設したシール溝８０ａに収容、保持され、このシール溝８０ａは、ボルト２４を迂回するようにして閉塞面８０に凹設される。 The seal member 25 is housed and held in a seal groove 80a recessed in the closing surface 80, and the seal groove 80a is recessed in the closing surface 80 so as to bypass the bolt 24.

また蓋本体８ｍの外面には、ポンプユニットＰからの吐出燃料の取出しに用いる燃料出口管８ａと、ポンプユニットＰへの給電に用いる給電カプラ８ｃとが、何れも燃料タンクＴ外に張出すようにして突設（本実施形態では合成樹脂の一体成形）される。図示はしないが、燃料出口管８ａは、エンジンの燃料噴射弁に連なる外部配管に接続可能であり、また給電カプラ８ｃは、ポンプユニットＰのモータ部に通じる給電端子２９を固定し且つそれを電子制御装置に連なる外部配線に接続可能である。 Further, on the outer surface of the lid body 8 m, the fuel outlet pipe 8a used for taking out the discharged fuel from the pump unit P and the power supply coupler 8c used for supplying power to the pump unit P are both extended to the outside of the fuel tank T. (In this embodiment, the synthetic resin is integrally molded). Although not shown, the fuel outlet pipe 8a can be connected to an external pipe connected to the fuel injection valve of the engine, and the power supply coupler 8c fixes the power supply terminal 29 leading to the motor portion of the pump unit P and electronically connects it. It can be connected to the external wiring connected to the control device.

筐体２０は、蓋８の前記取付台部８ｂに着脱可能に接合する筐体基部２１と、筐体基部２１に一体に連設される筐体主部２２と、筐体主部２２に着脱可能に結合されるエンドブロック２３とを備える。取付台部８ｂ及び筐体基部２１相互間、並びに筐体基部２１及びエンドブロック２３相互間の結合構造として、本実施形態では何れもスナップフィット式係合構造Ｊ１，Ｊ２が採用され、その係合構造Ｊ１，Ｊ２は、例えば、上記した相互間の一方に設けた係止爪と、相互間の他方に設けられて係止爪に係脱可能且つ弾力的に係合可能な係止孔とを有する。 The housing 20 is attached to and detached from the housing base 21 that is detachably joined to the mounting base portion 8b of the lid 8, the housing main portion 22 that is integrally connected to the housing base 21, and the housing main portion 22. It includes an end block 23 that can be coupled. In this embodiment, snap-fit type engaging structures J1 and J2 are adopted as the coupling structure between the mounting base portion 8b and the housing base 21 and between the housing base 21 and the end block 23, and the engaging structures thereof are adopted. The structures J1 and J2 have, for example, a locking claw provided on one side of each other and a locking hole provided on the other side of each other so as to be engaged with and elastically engaged with the locking claw.

筐体主部２２は、エンドブロック２３と協働してポンプユニットＰを保持する第１保持部２２１と、プレッシャレギュレータＲを保持する第２保持部２２２と、その両保持部２２１，２２２並びに筐体基部２１の相互間を一体に結合する連結壁部２２３とを備える。第１保持部２２１は、ポンプユニットＰの前端部を支持する前壁部２２１ｆと、前壁部２２１ｆから後方に各々延出してポンプユニットＰを上下より抱持する上下一対の把持腕部２２１ａ，２２１ｂとを有する。 The housing main portion 22 includes a first holding portion 221 that holds the pump unit P in cooperation with the end block 23, a second holding portion 222 that holds the pressure regulator R, both holding portions 221, 222, and a housing.

ところで蓋８の燃料出口管８ａは、蓋８の壁中を通る第１連通路３１と、筐体基部２２１及び連結壁部２２３の壁中を通る第２連通路３２とを介してポンプユニットＰの吐出部Ｐｃｏ及びプレッシャレギュレータＲの受圧部に連通している。第１連通路３１の内端、即ち上流端は、蓋８の取付台部８ｂの端面に開口する。 By the way, the fuel outlet pipe 8a of the lid 8 has a pump unit P via a first communication passage 31 passing through the wall of the lid 8 and a second communication passage 32 passing through the walls of the housing base portion 221 and the connecting wall portion 223. It communicates with the discharge part Pco of the above and the pressure receiving part of the pressure regulator R. The inner end, that is, the upstream end of the first passage 31, opens to the end surface of the mounting base portion 8b of the lid 8.

また第２連通路３２は、筐体基部２１の下面に下流端が開口し且つその開口から上方に直線状に立ち上がる縦通路部３２ｖと、ポンプユニットＰの吐出部Ｐｃｏを縦通路部３２ｖに連通させる第１横通路部３２ｈ１と、プレッシャレギュレータＲの受圧部を縦通路部３２ｖに連通させる第２横通路部３２ｈ２とを有しており、縦通路部３２ｖの下流端が第１連通路３１に直接連通する。 Further, in the second communication passage 32, a vertical passage portion 32v in which a downstream end opens on the lower surface of the housing base 21 and rises linearly upward from the opening, and a discharge portion Pco of the pump unit P communicate with the vertical passage portion 32v. It has a first horizontal passage portion 32h1 to be made to communicate and a second horizontal passage portion 32h2 to communicate the pressure receiving portion of the pressure regulator R with the vertical passage portion 32v, and the downstream end of the vertical passage portion 32v becomes the first communication passage 31. Communicate directly.

縦通路部３２ｖは、図４で明らかなようにポンプユニットＰの軸線Ｌｐと直交する投影面で見て、蓋８の閉塞面８０と直交する基準線Ｌｘに対し閉塞面８０の上端側に所定の傾斜角度θだけ傾斜して延びており、本発明の傾斜通路部を構成する。前記傾斜角度θは、傾斜通路部としての縦通路部３２ｖの軸線Ｚが、前記投影面で見て蓋８（取付台部８ｂ）から略鉛直に（従って側部タンク部Ｔｓの外側壁１００に略沿って）延びるような配置となるよう設定される。 As is clear from FIG. 4, the vertical passage portion 32v is defined on the upper end side of the closing surface 80 with respect to the reference line Lx orthogonal to the closing surface 80 of the lid 8 when viewed from the projection plane orthogonal to the axis Lp of the pump unit P. It is inclined and extended by the inclination angle θ of the above, and constitutes the inclined passage portion of the present invention. The inclination angle θ is such that the axis Z of the vertical passage portion 32v as the inclined passage portion is substantially vertically perpendicular to the lid 8 (mounting base portion 8b) when viewed from the projection surface (thus, on the outer wall 100 of the side tank portion Ts). It is set to extend (almost along).

次にエンドブロック２３の一例を、主として図２〜図４を参照して説明する。エンドブロック２３は、筐体主部２２における第１保持部２２１の後方開放端を閉じてポンプユニットＰの第１保持部２２１からの抜け出しを阻止する端壁としての機能に加え、フィルタ４０を筐体２０に支持させるフィルタ取付枠としての機能も有する。 Next, an example of the end block 23 will be described mainly with reference to FIGS. 2 to 4. The end block 23 has a function as an end wall for closing the rear open end of the first holding portion 221 in the housing main portion 22 to prevent the pump unit P from coming out of the first holding portion 221 and housing the filter 40. It also has a function as a filter mounting frame to be supported by the body 20.

即ち、エンドブロック２３は、第１保持部２２１に保持されたポンプユニットＰの後端を覆うブロック本体２３ｍを主要部としており、そのブロック本体２３ｍは、これの前端部の上・下部において、第１保持部２２１の把持腕部２２１ａ，２２１ｂをそれぞれ挿通させる上・下の挿通孔２３ｍａ，２３ｍｂをそれぞれ有して前後方向に延びている。そして、ブロック本体２３ｍの外周面と、各把持腕部２２１ａ，２２１ｂの二股状に分かれた先端部（後端部）との間に前述のスナップフィット式係合構造Ｊ２が設けられる。 That is, the end block 23 has a block main body 23m that covers the rear end of the pump unit P held by the first holding portion 221 as a main part, and the block main body 23m is the first in the upper and lower portions of the front end portion thereof. It has upper and lower insertion holes 23ma and 23mb through which the gripping arm portions 221a and 221b of the holding portion 221 are inserted, respectively, and extends in the front-rear direction. Then, the snap-fit type engaging structure J2 described above is provided between the outer peripheral surface of the block body 23 m and the bifurcated tip (rear end) of each of the gripping arms 221a and 221b.

また、ブロック本体２３ｍの後部一側面には、フィルタ４０の被取付部４０ａ（図２参照）が結合される。フィルタ４０は、例えば網材で扁平袋状に形成された柔軟な外皮内に濾材を収納して構成され、その外皮の一側面に、濾材内に連通する被取付部４０ａが接合される。尚、被取付部４０ａは、ブロック本体２３ｍに対し着脱可能に結合してもよいし、或いは着脱不能に結合してもよい。 Further, a mounted portion 40a (see FIG. 2) of the filter 40 is coupled to one side surface of the rear portion of the block body 23 m. The filter 40 is configured by accommodating a filter medium in a flexible outer skin formed of, for example, a net material in a flat bag shape, and an attached portion 40a communicating with the inside of the filter medium is joined to one side surface of the outer skin. The attached portion 40a may be detachably connected to the block main body 23m, or may be detachably connected to the block body 23m.

また、ブロック本体２３ｍは、ポンプユニットＰの吸入部Ｐｃｉをフィルタ４０の燃料出口に連通させる内部油路２３ｍｐと、その内部油路２３ｍｐの後端屈曲部に対応してブロック本体２３ｍの後端面より張出す膨出部２３ｍｃとを備えており、膨出部２３ｍｃは被取付部４０ａと接合される。 Further, the block body 23m is from the rear end surface of the block body 23m corresponding to the internal oil passage 23mp that communicates the suction portion Pci of the pump unit P with the fuel outlet of the filter 40 and the rear end bending portion of the internal oil passage 23mp. It is provided with an overhanging bulge portion 23 mc, and the bulge portion 23 mc is joined to the attached portion 40a.

ところで図２，図４で明らかなように、ポンプユニットＰの軸線Ｌｐと直交する投影面で見て、フィルタ４０は、軸線Ｌｐよりも蓋８の閉塞面８０の下端側（図２で左側）にオフセット配置される。またプレッシャレギュレータＲは、傾斜通路部として縦通路部３２ｖの軸線方向でポンプユニットＰの一方側（図示例で上方側）に配置される。尚、プレッシャレギュレータＲとポンプユニットＰとの位置関係を本実施形態とは上下逆にして、プレッシャレギュレータＲを縦通路部３２の軸線方向でポンプユニットＰの下方側に配置してもよい。 By the way, as is clear from FIGS. 2 and 4, when viewed from the projection plane orthogonal to the axis Lp of the pump unit P, the filter 40 is located on the lower end side of the closed surface 80 of the lid 8 (left side in FIG. 2) with respect to the axis Lp. Is offset to. Further, the pressure regulator R is arranged as an inclined passage portion on one side (upper side in the illustrated example) of the pump unit P in the axial direction of the vertical passage portion 32v. The positional relationship between the pressure regulator R and the pump unit P may be upside down from that of the present embodiment, and the pressure regulator R may be arranged below the pump unit P in the axial direction of the vertical passage portion 32.

また、蓋８には、前記した給電端子２９に通じる不図示の複数の接続部が設けられる。そして、これら接続部には、図示はしないがポンプユニットＰのモータ部から延びる配線が着脱可能に接続され、また必要に応じて蓋８又は筐体２０に取付けた液面センサから延びる配線が着脱可能に接続される。 Further, the lid 8 is provided with a plurality of connection portions (not shown) leading to the power supply terminal 29 described above. Although not shown, wiring extending from the motor portion of the pump unit P is detachably connected to these connection portions, and wiring extending from the liquid level sensor attached to the lid 8 or the housing 20 is detachably connected as needed. Can be connected.

次に実施形態の作用について説明する。燃料ポンプモジュールＦＭは、本実施形態では蓋８に支持されてポンプユニットＰを保持する筐体２０が、ポンプ吐出部Ｐｃｏ及び蓋８の燃料出口管８ａとの間を連通させる第２連通路３２を有し、蓋８は、燃料タンクＴの開口部７の蓋８による閉塞状態で、開口部７の周縁部に対し平行で且つシール部材２５を介して液密に接触する閉塞面８０を有し、ポンプユニットＰは、ポンプ軸線Ｌｐが前後方向に延びて閉塞面８０と略平行となるよう筐体２０に保持される。そして、蓋８の閉塞面８０は、上記閉塞状態で、ポンプ軸線Ｌｐと直交する投影面（特に図４を参照）で見て、水平面に対し外方下側に傾斜しており、筐体２０内の第２連通路３２は、上記投影面で見て、閉塞面８０と直交する基準線Ｌｘに対し閉塞面８０の上端側に傾斜した傾斜通路部としての縦通路部３２ｖを有する。 Next, the operation of the embodiment will be described. In the fuel pump module FM, in the present embodiment, the housing 20 that is supported by the lid 8 and holds the pump unit P communicates between the pump discharge portion Pco and the fuel outlet pipe 8a of the lid 8. The lid 8 has a closed surface 80 that is parallel to the peripheral edge of the opening 7 and is in liquid-tight contact with the seal member 25 in a closed state by the lid 8 of the opening 7 of the fuel tank T. The pump unit P is held in the housing 20 so that the pump axis Lp extends in the front-rear direction and is substantially parallel to the closing surface 80. The closed surface 80 of the lid 8 is inclined outward and downward with respect to the horizontal plane when viewed from a projection surface (particularly see FIG. 4) orthogonal to the pump axis Lp in the closed state, and the housing 20 The second continuous passage 32 inside has a vertical passage portion 32v as an inclined passage portion inclined toward the upper end side of the closing surface 80 with respect to the reference line Lx orthogonal to the closing surface 80 when viewed from the projection plane.

これにより、蓋８の閉塞面８０が開口部７の閉塞状態で水平面に対し傾斜するも、その傾斜に伴う燃料ポンプモジュールＦＭの傾倒、即ち、蓋８の位置を基準とした燃料ポンプモジュールＦＭの横方向張出し（従って燃料タンクＴの外側方への張出し）が効果的に抑えられる。従って、燃料タンクＴを小型化する上で頗る有利となり、また小型の燃料タンクＴ内にも燃料ポンプモジュールＦＭを無理なく配備可能となる。 As a result, the closed surface 80 of the lid 8 is tilted with respect to the horizontal plane in the closed state of the opening 7, but the fuel pump module FM is tilted due to the tilt, that is, the fuel pump module FM is tilted with reference to the position of the lid 8. Lateral overhang (and therefore outward overhang of the fuel tank T) is effectively suppressed. Therefore, it is extremely advantageous in reducing the size of the fuel tank T, and the fuel pump module FM can be reasonably deployed in the small fuel tank T.

これに対して、図５に示す比較例の燃料ポンプモジュールＦＭ″では、蓋８の傾斜した閉塞面８０に対し第２連通路３２ｖ″が直角方向に（即ち蓋８の中心を通る鉛直面Ｌｖに対し外上方に傾斜して）長く延出しており、これに伴い、鉛直面Ｌｖに対し傾倒した燃料供給装置ＦＭ″の上端部が蓋８から横方向に少なからず張出してしまう。従って、その横方向に張出した燃料供給装置ＦＭ″の上端部を避けるために、側部タンク部Ｔｓ″の対応する外側壁１００″を外側方に張出させる必要があり、それだけ燃料タンクＴ″が大型化してしまう不都合がある。即ち、比較例の側部タンク部Ｔｓ″の横幅をＷ２とし、本実施形態の側部タンク部Ｔｓの横幅をＷ１とすれば、Ｗ２＞Ｗ１となる。 On the other hand, in the fuel pump module FM "of the comparative example shown in FIG. 5, the second communication passage 32v" is perpendicular to the inclined closed surface 80 of the lid 8 in the direction perpendicular to the direction (that is, the vertical surface Lv passing through the center of the lid 8). The upper end of the fuel supply device FM "inclined with respect to the vertical Lv protrudes laterally from the lid 8 due to the long extension (inclining outward and upward). In order to avoid the upper end of the fuel supply device FM ″ overhanging in the lateral direction, it is necessary to extend the corresponding outer wall 100 ″ of the side tank portion Ts ″ to the outside, and the fuel tank T ″ becomes larger accordingly. That is, if the width of the side tank portion Ts "of the comparative example is W2 and the width of the side tank portion Ts of the present embodiment is W1, then W2> W1.

また本実施形態では、ポンプユニットＰの吸入部Ｐｃｉに連なるフィルタ４０が、ポンプ軸線Ｌｐと直交する投影面（図２，図４参照）で見て、ポンプ軸線Ｌｐよりも閉塞面８０の下端側にオフセット配置される。これにより、燃料タンクＴの、外方下側に傾斜した底壁部１１の低位側にフィルタ４０が偏位するため、側部タンク部Ｔｓ内の燃料油量が少なくなった場合でも、ポンプユニットＰは、低位側に偏在するフィルタ４０を通して燃料を吸引可能となる。 Further, in the present embodiment, the filter 40 connected to the suction portion Pci of the pump unit P is located on the lower end side of the closed surface 80 with respect to the pump axis Lp when viewed from the projection plane (see FIGS. 2 and 4) orthogonal to the pump axis Lp. Is offset to. As a result, the filter 40 is displaced to the lower side of the bottom wall portion 11 inclined outwardly downward of the fuel tank T, so that even if the amount of fuel oil in the side tank portion Ts is reduced, the pump unit P can suck fuel through the filter 40 which is unevenly distributed on the lower side.

また本実施形態では、筐体２０に保持したプレッシャレギュレータＲとポンプユニットＰとが前記投影面で見て縦通路部３２ｖの軸線方向に並ぶ配置となることで、筐体２０、延いては燃料ポンプモジュールＦＭの全高が高くなってしまうが、本実施形態では縦通路部３２ｖの前述の傾斜配置効果に基づき燃料ポンプモジュールＦＭの傾倒（即ち横方向張出し）が抑えられるため、燃料タンクＴを小型化した場合でも、全高の高い燃料ポンプモジュールＦＭを燃料タンクＴ内に無理なく配備可能となる。 Further, in the present embodiment, the pressure regulator R and the pump unit P held in the housing 20 are arranged so as to be arranged in the axial direction of the vertical passage portion 32v when viewed from the projection surface, so that the housing 20 and thus the fuel Although the overall height of the pump module FM becomes high, in the present embodiment, the fuel tank T is made smaller because the tilting (that is, lateral overhang) of the fuel pump module FM is suppressed based on the above-mentioned tilting arrangement effect of the vertical passage portion 32v. Even if the fuel pump module FM has a high overall height, it can be easily deployed in the fuel tank T.

また本実施形態の燃料タンクＴは、車体の車両中央を通るメインフレーム６を跨ぐ中間タンク部Ｔｍと、それの左右両側より一体に垂下する一対の側部タンク部Ｔｓ，Ｔｓ′とを有して鞍状に形成されると共に、一方の側部タンク部Ｔｓの、外方下側に傾斜した底壁部１１に開口部７が設けられて燃料ポンプモジュールＦＭが設置されるため、その開口部７を閉塞する蓋８、及びそれから張出す燃料出口管８ａや給電カプラ８ｃが、燃料タンクＴ、特に一対の側部タンク部Ｔｓ，Ｔｓ′の外側壁で効果的に遮蔽される。これにより、それら蓋８、燃料出口管８ａ及び給電カプラ８ｃは、他物の衝突から有効に保護され、しかも燃料タンクＴにより体裁よく隠蔽されて製品の美観向上が図られる。 Further, the fuel tank T of the present embodiment has an intermediate tank portion Tm straddling the main frame 6 passing through the center of the vehicle body, and a pair of side tank portions Ts and Ts' hanging from both the left and right sides of the intermediate tank portion Tm. In addition to being formed in a saddle shape, an opening 7 is provided in the bottom wall portion 11 of one side tank portion Ts that is inclined outward and downward to install the fuel pump module FM. The lid 8 that closes the 7 and the fuel outlet pipe 8a and the power supply coupler 8c that project from the lid 8 are effectively shielded by the outer wall of the fuel tank T, particularly the pair of side tank portions Ts and Ts'. As a result, the lid 8, the fuel outlet pipe 8a, and the power feeding coupler 8c are effectively protected from collisions with other objects, and are also aesthetically concealed by the fuel tank T to improve the aesthetic appearance of the product.

ところで前記実施形態では、側部タンク部Ｔｓの外方下側に傾斜した底壁部１１に開口部７を設けて燃料ポンプモジュールＦＭを設置するものを示した。これに対して、図示はしないが、側部タンク部Ｔｓ′の車両中央側を向く側壁部１２が外方下側に傾斜している場合には、その側壁部１２に開口部７を設けて燃料ポンプモジュールＦＭを設置してもよい。その場合においても、傾斜通路部としての縦通路部３２ｖを基準線Ｌｘに対し特定方向に傾斜させる点は、前記実施形態と同様である。 By the way, in the above-described embodiment, the fuel pump module FM is installed by providing the opening 7 in the bottom wall portion 11 inclined to the outer lower side of the side tank portion Ts. On the other hand, although not shown, when the side wall portion 12 of the side tank portion Ts' facing the vehicle center side is inclined outward and downward, an opening 7 is provided in the side wall portion 12. A fuel pump module FM may be installed. Even in that case, the point that the vertical passage portion 32v as the inclined passage portion is inclined in a specific direction with respect to the reference line Lx is the same as that of the above-described embodiment.

A fuel pump module FM as a fuel supply device may be installed on the inclined bottom wall portion or side wall portion of the fuel tank.
