Description

本発明は、燃料タンクへ給油するための燃料タンクの開閉装置に関する。   The present invention relates to a fuel tank opening and closing device for refueling a fuel tank.

燃料タンクの給油装置として、特許文献１の技術が知られている。給油装置は、燃料タンクに接続される給油管と、給油管の開口部にネジ込まれるとともに給油管の給油口を開閉する燃料キャップと、給油管内に配置され、給油ノズルの外周部をシールするゴム製のノズルシール部材と、給油管内の圧力が所定圧を越えたときに該圧力を外部に対して抜くためのリリーフ弁と、を備えている。こうした給油装置において、給油の際に、燃料キャップを給油管から外して、給油口から給油ノズルを差し込み、さらに、給油ノズルをノズルシール部材の挿入通路に挿入することで、給油ノズルから吐出した燃料を燃料通路を介して燃料タンクへ供給している。ノズルシール部材は、給油ノズルの外周面を押圧することで、給油口からの燃料の流出を防止している。   The technique of patent document 1 is known as a fuel tank fueling device. The fueling device is disposed in the fueling pipe connected to the fuel tank, a fuel cap that is screwed into the opening of the fueling pipe and opens and closes the fueling port of the fueling pipe, and seals the outer periphery of the fueling nozzle. A rubber nozzle seal member and a relief valve for releasing the pressure from the outside when the pressure in the oil supply pipe exceeds a predetermined pressure are provided. In such a fueling device, when fueling, the fuel discharged from the fueling nozzle is removed by removing the fuel cap from the fueling tube, inserting the fueling nozzle from the fueling port, and inserting the fueling nozzle into the insertion passage of the nozzle seal member. Is supplied to the fuel tank through the fuel passage. The nozzle seal member prevents the fuel from flowing out from the fuel filler port by pressing the outer peripheral surface of the fuel filler nozzle.

特表２００５−５３７９８１号Special table 2005-537981

従来の技術にかかる給油装置において、ノズルシール部材は、燃料キャップと干渉しないように給油管のネジより奥側（燃料タンク側）へ配置している。このため、ノズルシール部材を、給油管のネジを乗り越えて装着しなければならず、装着作業が面倒であった。また、リリーフ弁も給油口の周辺に配置されており、給油ノズルの先端で損傷を受けやすいという課題もあった。   In the fueling device according to the conventional technology, the nozzle seal member is disposed on the back side (fuel tank side) from the screw of the fueling pipe so as not to interfere with the fuel cap. For this reason, the nozzle seal member has to be mounted over the screw of the oil supply pipe, and the mounting operation is troublesome. In addition, the relief valve is also disposed around the oil filler port, and there is a problem that the tip of the oil nozzle is easily damaged.

本発明は、上述の課題の少なくとも一部を解決するためになされたものであり、以下の形態として実現することが可能である。   SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms.

（１） 本発明の一形態は、燃料タンクの開閉装置である。燃料タンクの開閉装置は、給油ノズルから吐出される燃料を燃料タンクへ供給する燃料通路を開閉する燃料タンクの開閉装置において、 上記燃料通路を形成するタンク開口形成部材と、上記燃料通路の一部である注入口と、該注入口の外側であり燃料通路の一部を構成する挿入通路と、上記注入口の内側であり上記燃料通路の一部を構成するタンク側通路とを有する注入口形成部材と、上記注入口を開閉する注入口開閉機構と、上記挿入通路を形成し、該挿入通路を通じて挿入された給油ノズルを上記注入口へガイドするための通路形成部材と、上記挿入通路内に配置され給油ノズルの外周部に密着するシール部材と、上記通路形成部材に設けられ該シール部材を保持するためのノズルシール収容部とを有するノズルシール機構と、上記挿入通路と上記タンク側通路とを接続するとともに、上記ノズルシール機構をバイパスする通気路を形成する弁室形成部材と、上記通気路を開閉する弁体とを有し、上記タンク側通路が所定圧を越えたときに上記弁体が上記通気路を開く弁機構と、上記通路形成部材および上記ノズルシール収容部に装着されるとともに給油ノズルの先端が上記シール部材に当たるのを防止するシールカバー部材と、を備え、上記シールカバー部材は、上記弁室形成部材の一部を構成する蓋体を有する構成をとることができる。 (1) One embodiment of the present invention is a fuel tank opening and closing device. The fuel tank opening and closing device is a fuel tank opening and closing device that opens and closes a fuel passage that supplies fuel discharged from a fuel nozzle to the fuel tank, a tank opening forming member that forms the fuel passage, and a part of the fuel passage And an inlet passage that is outside the inlet and forms part of the fuel passage, and a tank side passage that is inside the inlet and forms part of the fuel passage. A member, an inlet opening / closing mechanism that opens and closes the inlet, a passage forming member that forms the insertion passage and guides the oiling nozzle inserted through the insertion passage to the inlet, and the insertion passage A nozzle seal mechanism having a seal member disposed and in close contact with the outer peripheral portion of the oil supply nozzle; and a nozzle seal housing portion provided in the passage forming member for holding the seal member; A valve chamber forming member that connects the passage and the tank-side passage, and that forms a vent passage that bypasses the nozzle seal mechanism; and a valve body that opens and closes the vent passage, and the tank-side passage has a predetermined pressure. A valve mechanism in which the valve body opens the vent passage when the pressure exceeds, and a seal cover member that is mounted on the passage forming member and the nozzle seal housing portion and prevents the tip of the fueling nozzle from hitting the seal member; The seal cover member can have a configuration including a lid that forms a part of the valve chamber forming member.

本形態において、給油ノズルの先端をノズルシール機構のシール部材に挿入すると、給油ノズルがシール部材によりシールされた状態にて、注入口から燃料タンクのタンク側通路へ挿入される。よって、給油の際に、給油ノズルがノズルシール機構により外部に対してシールされるから、燃料蒸気の外部への放出量を低減することができる。また、給油時に、給油ノズルがノズルシール機構によりシールされた状態において、タンク側通路の圧力が弁機構の開弁圧を越えると弁体が開き、通気路が連通する。これにより、燃料蒸気の放出量を抑制した状態で、タンク側通路の圧力が低くなり、給油の円滑な作業を行なうことができる。さらに、シールカバー部材は、シール部材を保護する部材としての機能のほかに、弁機構の弁室形成部材の一部である蓋体を有し、給油ノズルの先端が弁機構の弁体などに当たるのを防止する。シールカバー部材は、１つの部材でシール部材および弁機構の弁体などを保護する機能を兼用しているから、部品点数および組付工数を少なくする。   In this embodiment, when the tip of the fuel nozzle is inserted into the seal member of the nozzle seal mechanism, the fuel nozzle is inserted from the inlet into the tank side passage of the fuel tank while being sealed by the seal member. Therefore, when refueling, the refueling nozzle is sealed to the outside by the nozzle seal mechanism, so the amount of fuel vapor released to the outside can be reduced. Further, when the oil supply nozzle is sealed by the nozzle seal mechanism at the time of refueling, the valve body opens when the pressure in the tank side passage exceeds the valve opening pressure of the valve mechanism, and the ventilation path communicates. As a result, the pressure in the tank-side passage is reduced in a state where the amount of fuel vapor released is suppressed, and a smooth refueling operation can be performed. Furthermore, the seal cover member has a lid body that is a part of the valve chamber forming member of the valve mechanism in addition to the function as a member that protects the seal member, and the tip of the oil supply nozzle hits the valve body of the valve mechanism and the like. To prevent. Since the seal cover member also has a function of protecting the seal member and the valve body of the valve mechanism with a single member, the number of parts and the number of assembly steps are reduced.

図１に示すように、給油蓋ＦＬを開けると、給油室ＦＲ内に配置された燃料タンクの開閉装置１０が表れる。図６に示すように、給油ノズルＦＮを開口形成部材２３の挿入用開口２３ｂに挿入して、給油ノズルＦＮの先端が挿入側開閉機構４０の開閉部材４１の上面を押圧すると、開閉部材４１は、軸受部４２のスプリング４３の付勢力に抗して回動して開き動作する。さらに、給油ノズルＦＮの先端をノズルシール機構４５のシール用通路４５Ｐに挿入すると、給油ノズルＦＮの先端および外周部がノズルシール機構４５のシール部材４８のリップ４８ｂを外方へ撓ませて、給油ノズルＦＮが燃料タンク側へ挿入される。 (3) Opening / Closing Operation of Fuel Tank Opening / Closing Device 10 Next, a fueling operation by the fuel nozzle to the fuel tank opening / closing device 10 will be described.
(3) -1 Opening Operation As shown in FIG. 1, when the fueling lid FL is opened, the fuel tank opening / closing device 10 disposed in the fueling chamber FR appears. As shown in FIG. 6, when the refueling nozzle FN is inserted into the insertion opening 23 b of the opening forming member 23 and the tip of the refueling nozzle FN presses the upper surface of the opening / closing member 41 of the insertion side opening / closing mechanism 40, the opening / closing member 41 is Rotating and opening operation is performed against the urging force of the spring 43 of the bearing portion 42. Further, when the front end of the oil supply nozzle FN is inserted into the seal passage 45P of the nozzle seal mechanism 45, the front end and the outer periphery of the oil supply nozzle FN deflect the lip 48b of the seal member 48 of the nozzle seal mechanism 45 outward, and supply oil. The nozzle FN is inserted into the fuel tank side.

給油ノズルＦＮをさらに押し入れると、給油ノズルＦＮの先端が注入口開閉機構６０の開閉部材６１の上面に当たり、開閉部材６１が軸受部６２を中心にスプリング６３の付勢力に抗して回動する。これにより、給油ノズルＦＮがタンク側通路１１Ｐｂに挿入される。そして、この状態にて、給油ノズルＦＮからタンク側通路１１Ｐｂに給油する。燃料が燃料タンクの満タン液位を越えてタンク側通路１１Ｐｂ内を燃料が上昇する。そして、給油ノズルＦＮの先端付近のセンサで燃料を検知すると、給油ノズルＦＮのオートストップが作動して、給油が停止する。
こうした給油動作の際に、ノズルシール機構４５より燃料タンク側の通路の圧力が弁機構５０の開弁圧を越えると、弁機構５０が開弁して、燃料通路１１Ｐの圧力が外部へ逃がされる。 When the fueling nozzle FN is further pushed in, the tip of the fueling nozzle FN hits the upper surface of the opening / closing member 61 of the inlet opening / closing mechanism 60, and the opening / closing member 61 rotates around the bearing portion 62 against the urging force of the spring 63. . Thereby, the fueling nozzle FN is inserted into the tank side passage 11Pb. In this state, fuel is supplied from the oil supply nozzle FN to the tank side passage 11Pb. The fuel rises in the tank side passage 11Pb after the fuel tank reaches the full tank level. When fuel is detected by a sensor near the tip of the fueling nozzle FN, the auto-stop of the fueling nozzle FN is activated and fueling is stopped.
During such a refueling operation, if the pressure in the fuel tank side passage from the nozzle seal mechanism 45 exceeds the valve opening pressure of the valve mechanism 50, the valve mechanism 50 opens and the pressure in the fuel passage 11P is released to the outside. .

（３）−２ 閉じ動作
給油を終えて、給油ノズルＦＮを注入口２６ａから抜くと、注入口開閉機構６０の開閉部材６１がスプリング６３の復元力により回動して注入口２６ａを閉じる。さらに給油ノズルＦＮが外側へ移動すると、ノズルシール機構４５のシール用通路４５Ｐから抜かれ、給油ノズルＦＮとシール部材４８とのシールが解除される。さらに、給油ノズルＦＮが抜かれると、挿入側開閉機構４０の開閉部材４１が軸受部４２のスプリング４３の復元力により回動して挿入用開口２３ｂを閉じる。さらに、給油蓋ＦＬ（図１）を閉じることで、給油作業が終了する。 (3) -2 Closing Operation When refueling is completed and the fuel supply nozzle FN is removed from the injection port 26a, the opening / closing member 61 of the injection port opening / closing mechanism 60 is rotated by the restoring force of the spring 63 to close the injection port 26a. When the fuel supply nozzle FN further moves outward, it is removed from the seal passage 45P of the nozzle seal mechanism 45, and the seal between the fuel supply nozzle FN and the seal member 48 is released. Further, when the fuel supply nozzle FN is removed, the opening / closing member 41 of the insertion side opening / closing mechanism 40 is rotated by the restoring force of the spring 43 of the bearing portion 42 to close the insertion opening 23b. Further, the refueling operation is completed by closing the refueling lid FL (FIG. 1).

（４） 燃料タンクの開閉装置１０の作用・効果
上記実施例にかかる燃料タンクの開閉装置１０により、以下の作用効果を奏する。 (4) Operation / Effect of Fuel Tank Opening / Closing Device 10 The fuel tank opening / closing device 10 according to the embodiment provides the following operational effects.

（４）−１ 図６に示すように、給油ノズルＦＮの先端をノズルシール機構４５のシール用通路４５Ｐに挿入すると、給油ノズルＦＮの先端および外周部がノズルシール機構４５のシール部材４８のリップ４８ｂを外方へ撓ませて、給油ノズルＦＮが燃料タンク側へ挿入される。給油の際に、給油ノズルＦＮから燃料が吐出される部分がノズルシール機構４５により外部に対してシールされるから、燃料蒸気への放出量を低減することができる。 (4) -1 As shown in FIG. 6, when the tip of the oil supply nozzle FN is inserted into the seal passage 45 </ b> P of the nozzle seal mechanism 45, the tip and the outer periphery of the oil supply nozzle FN are the lip of the seal member 48 of the nozzle seal mechanism 45. The fuel supply nozzle FN is inserted into the fuel tank side by bending 48b outward. During fueling, the portion from which fuel is discharged from the fueling nozzle FN is sealed to the outside by the nozzle seal mechanism 45, so that the amount of fuel vapor released can be reduced.

（４）−２ 給油時に、給油ノズルＦＮがノズルシール機構４５によりシールされた状態において、燃料通路１１Ｐのタンク側通路１１Ｐｂの圧力が弁機構５０の開弁圧を越えると弁体５４が開き、通気路５０Ｐが連通する。これにより、燃料蒸気の放出量を抑制した状態で、タンク側通路１１Ｐｂ側の燃料蒸気が外部へ最小限の量だけ逃がされることで、給油の円滑な作業を行なうことができる。 (4) -2 At the time of refueling, in the state where the fuel nozzle FN is sealed by the nozzle seal mechanism 45, the valve body 54 opens when the pressure of the tank side passage 11Pb of the fuel passage 11P exceeds the valve opening pressure of the valve mechanism 50, The air passage 50P communicates. As a result, the fuel vapor on the tank side passage 11Pb is released to the outside by a minimum amount in a state in which the amount of fuel vapor released is suppressed, and a smooth operation of refueling can be performed.

（４）−３ 図４および図５に示すように、シールカバー部材４７は、シール部材４８および弁機構５０の上部を覆っており、給油ノズルＦＮが挿入される際に、給油ノズルＦＮの先端がシール部材４８や弁機構５０の弁体５４などに当たるのを防止する。シールカバー部材４７は、シール部材４８および弁機構５０を保護するのを１つの部材で行なっているから、部品点数および組付工数を少なくする。 (4) -3 As shown in FIGS. 4 and 5, the seal cover member 47 covers the upper portions of the seal member 48 and the valve mechanism 50, and the tip of the oil supply nozzle FN when the oil supply nozzle FN is inserted. Is prevented from hitting the seal member 48, the valve body 54 of the valve mechanism 50, and the like. Since the seal cover member 47 protects the seal member 48 and the valve mechanism 50 with a single member, the number of parts and assembly man-hours are reduced.

（４）−４ ノズルシール機構４５は、注入口開閉機構６０の上流側で、つまり開口部２３ａ側に配置されているから、給油ノズルＦＮの根元の部分をシールする。したがって、ノズルシール機構４５は、短い給油ノズルＦＮであっても、給油時に、確実にシールし、燃料蒸気の外部への放出量を低減できる。 (4) -4 The nozzle seal mechanism 45 is disposed on the upstream side of the inlet opening / closing mechanism 60, that is, on the opening 23a side, and therefore seals the base portion of the fuel supply nozzle FN. Therefore, the nozzle seal mechanism 45 can reliably seal even when the fuel supply nozzle FN is short, and can reduce the amount of fuel vapor released to the outside.

（４）−５ ノズルシール機構４５が注入口開閉機構６０の上流側に配置されているから、給油のオートストップの後に、追加給油によって、燃料液位が注入口開閉機構６０を越えても、ノズルシール機構４５に達し難い。よって、ノズルシール機構４５のシール部材４８が燃料に浸かりにくいから、シール部材４８のゴム材料として、燃料膨潤性を特に考慮する必要がなく、高価なフッ素系ゴムだけでなく、シリコンゴムやＥＰＤＭなどのゴム材料も用いることができ、シール用の材料の選択性を広げることができる。 (4) -5 Since the nozzle seal mechanism 45 is arranged on the upstream side of the inlet opening / closing mechanism 60, even if the fuel level exceeds the inlet opening / closing mechanism 60 by additional refueling after automatic refueling, the nozzle It is difficult to reach the seal mechanism 45. Therefore, since the seal member 48 of the nozzle seal mechanism 45 is difficult to be immersed in the fuel, it is not particularly necessary to consider the fuel swellability as the rubber material of the seal member 48, and not only expensive fluorine-based rubber but also silicon rubber, EPDM, etc. These rubber materials can also be used, and the selectivity of the sealing material can be expanded.

（４）−６ 通路形成部材２４は、挿入用開口２３ｂと注入口２６ａとを接続する挿入通路１１Ｐａを形成するとともに、給油ノズルＦＮを挿入用開口２３ｂから注入口２６ａへガイドし、給油作業を容易にする。 (4) -6 The passage forming member 24 forms the insertion passage 11Pa that connects the insertion opening 23b and the injection port 26a, and guides the oil supply nozzle FN from the insertion opening 23b to the injection port 26a, thereby performing the oil supply operation. make it easier.

（４）−７ 挿入側開閉機構４０は、給油時以外にタンク開口形成部材１１の挿入用開口２３ｂを閉じているから、挿入用開口２３ｂ、挿入通路１１Ｐａを通じて注入口開閉機構６０に達する大気中の塵などを防ぎ、注入口開閉機構６０のシール性の低下を防止することができる。 (4) -7 The insertion side opening / closing mechanism 40 closes the insertion opening 23b of the tank opening forming member 11 except during refueling. Therefore, the insertion side opening / closing mechanism 40 reaches the inlet opening / closing mechanism 60 through the insertion opening 23b and the insertion passage 11Pa. It is possible to prevent dust and the like, and to prevent deterioration of the sealing performance of the inlet opening / closing mechanism 60.

なお、この発明は上記実施例に限られるものではなく、その要旨を逸脱しない範囲において種々の態様において実施することが可能である。
上記実施例において、シールカバー部材４７を通路形成部材２４に固定する手段として、爪による係合の他、溶着などの各種の手段を用いてもよい。 The present invention is not limited to the above-described embodiments, and can be implemented in various modes without departing from the scope of the invention.
