Description
本発明は、給油ノズル、より詳細には流量調整機構の構造に関する。
The present invention relates to a fuel nozzle, and more particularly to the structure of a flow rate adjustment mechanism.
給油ノズルにより給油する場合において車両の燃料タンクに満タンに給油する満タン給油や設定量分もしくは設定金額分の燃料油を給油するプリセット給油、さらには給油量を整数値で終える整数給油などにおいては給油の最終段階で微小流量での微量給油が必要となる。
When refueling with a refueling nozzle, full tank refueling that fills the fuel tank of the vehicle, preset refueling that refuels the set amount or amount of fuel oil, and integer refueling that ends the refueling amount with an integer value. requires a very small amount of lubrication at the final stage of lubrication.
このため、特許文献１に見られるようにプリセット給油や整数給油にあっては給油装置本体の電磁弁により流量を調整する方式や給油作業者が給油ノズルの給油レバーを手動で微小調整して流量を絞って行なわれている。
For this reason, as seen in Patent Document 1, in the case of preset lubrication or integer lubrication, there is a method in which the flow rate is adjusted by an electromagnetic valve on the main body of the lubrication device, or a lubrication operator manually finely adjusts the lubrication lever of the lubrication nozzle to adjust the flow rate. It is done by squeezing
後者の手動により微量給油を行う場合に適した給油ノズルとして図１０に示したように給油レバー1の変位量に連動し、且つバネ２により常時閉弁方向に付勢された弁棹３に設けられた主弁４に貫通孔５を形成し、この貫通孔５との開度を弁棹３（給油レバー１）により調整可能な小弁６で調整する流量制御機構７を設けた給油ノズルも実用化されている。
As a lubricating nozzle suitable for the latter manual small amount lubricating, as shown in FIG. The main valve 4 is formed with a through hole 5, and the opening of the through hole 5 is adjusted by a small valve 6 that can be adjusted by a valve stem 3 (refueling lever 1). It has been put to practical use.
この給油ノズルは、給油レバー１をバネ２の付勢力に抗して引き上げると、小弁６が主弁４から離れ貫通孔５が開通し、さらに限界点まで移動すると、今度は給油レバー１の移動量に対応するように主弁４が移動し、給油ホース接続口１０から流入した液をノズル筒先部から排出する。
When the fueling lever 1 is pulled up against the urging force of the spring 2, the small valve 6 is separated from the main valve 4 and the through hole 5 is opened. The main valve 4 moves so as to correspond to the amount of movement, and the liquid that has flowed in from the refueling hose connection port 10 is discharged from the tip of the nozzle.
一方、流量制御機構７は、主弁４が弁座に着座して小弁６が貫通孔５から離れている状態では、給油レバー１の変位量に小弁６が応動するため貫通孔５との開度が調整できる。微少流量領域での流量調整と閉弁時の密封性を確保するため、小弁６は図１１に示すように貫通孔５と対向する面６ａが円錐状（テーパ状）に形成されていて、中心の取り付け孔８が弁棹３の端部に固定されている。
On the other hand, in the flow rate control mechanism 7, when the main valve 4 is seated on the valve seat and the small valve 6 is separated from the through hole 5, the small valve 6 responds to the amount of displacement of the fuel supply lever 1. can be adjusted. As shown in FIG. 11, the small valve 6 has a conical (tapered) surface 6a facing the through hole 5 in order to adjust the flow rate in a very small flow rate range and to ensure sealing performance when the valve is closed. A central mounting hole 8 is fixed to the end of the valve stem 3 .
他方、主弁４は弁座９との密閉性を考慮してゴムなどの弾性材料により構成されていて、これがため、貫通孔５の外周に集中的に負荷がかかり摩耗するという恐れがある。
On the other hand, the main valve 4 is made of an elastic material such as rubber in consideration of the sealability with the valve seat 9, so there is a risk that the outer periphery of the through hole 5 will be subjected to concentrated load and wear.
本発明は、このような問題に鑑みてなされたものであってその目的とするところは、流量制御機構を構成する主弁の耐久性を向上させつつ容易に微小流量が調節できる給油ノズルを提供することである。
SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and an object thereof is to provide a fueling nozzle capable of easily adjusting a minute flow rate while improving durability of a main valve constituting a flow rate control mechanism. It is to be.
このような課題を解決するために本発明は、給油ホースからの液を流入口で受け、閉弁方向に常時付勢される弁棹を介して給油レバーにより開閉される主弁を経由させてノズル筒先部から排出させる給油ノズルにおいて、前記主弁の上流側に前記給油レバーにより操作可能な流量制御機構を備えた。
In order to solve such problems, the present invention receives the liquid from the oil supply hose at the inflow port, passes it through the main valve that is opened and closed by the oil supply lever, through the valve stem that is always urged in the valve closing direction. A fueling nozzle that discharges fuel from the tip of the nozzle includes a flow rate control mechanism that can be operated by the fueling lever on the upstream side of the main valve.
主弁の貫通孔の外面に小弁が面接触するとともに、小弁と貫通孔との間隙度、もしくは弁開度が給油レバーの変位量に対応する。
The small valve comes into surface contact with the outer surface of the through-hole of the main valve, and the gap between the small valve and the through-hole, or the degree of opening of the valve, corresponds to the amount of displacement of the refueling lever.
図１～３は、本発明の流量制御機構付き給油ノズルの一実施例を示すものであって、給油ホースからの液を流入口１１で受け、閉弁方向にバネ１２により常時付勢される弁棹１ ３を介して給油レバー１４により開閉される主弁１５を経由させてノズル筒先部１６から排出させる給油ノズルにおいて、主弁１５に貫通孔１７を形成し、この貫通孔１７を上流側に設けた小弁１８で開閉して貫通孔との開度を調整する流量制御機構１９を設けて構成されている。

A flow rate control mechanism 19 is provided for opening and closing with a small valve 18 provided at the bottom to adjust the degree of opening with respect to the through hole.
この実施例においては、小弁１８は、図３に示したように主弁１５の貫通孔１７に対向する面に弁棹１３と同芯状で、かつ貫通孔１７に進退可能な凸部２０、やはり貫通孔１７に進退可能で貫通孔１７との開度を調整する凸部２１、さらには主弁１５の貫通孔１７を閉塞する平面部２２が形成されている。
In this embodiment, as shown in FIG. 3, the small valve 18 has a convex portion 20 which is concentric with the valve stem 13 and which can advance and retreat through the through hole 17 on the surface facing the through hole 17 of the main valve 15. , a convex portion 21 which is also movable in and out of the through-hole 17 and adjusts the degree of opening with respect to the through-hole 17 , and a flat portion 22 which closes the through-hole 17 of the main valve 15 are formed.
この実施例によれば閉弁時には小弁１８の平面部２２が貫通孔１７の外周面と面接触して貫通孔１７を閉塞する。また微小流量調整時には流量調整用の凸部２１が弁棹１３の変位に応動して貫通孔１７を移動して貫通孔１７との隙間を変化させて微小な流量を調整することになる。
According to this embodiment, when the valve is closed, the flat portion 22 of the small valve 18 comes into surface contact with the outer peripheral surface of the through hole 17 to close the through hole 17 . Further, when the flow rate is minutely adjusted, the projection 21 for flow rate adjustment moves in the through hole 17 in response to the displacement of the valve stem 13 to change the gap with the through hole 17, thereby adjusting the minute flow rate.
これにより貫通孔１７の外周面を構成する領域１５ａ、つまり貫通孔１７の小弁に対向する領域には小弁１８の負荷が集中することなく閉弁できる。
As a result, the load of the small valve 18 can be closed without concentrating on the region 15a forming the outer peripheral surface of the through hole 17, that is, the region of the through hole 17 facing the small valve.
図４、５は、本発明の第二実施例を示すものであって、この実施例においては流量調整用凸部２１の側面に貫通孔側が小径となるようにテーパ部２３が形成されている。

この実施例によれば微小流量を凸部２１の切欠き部２４と貫通孔１７との隙間で調整することができ、微小流量を容易に調整できる。また切欠き部２４、２４を等間隔に形成することにより小弁１８にかかる圧力を均等にできて微小流量調整時の弁開度を安定化することができる。
According to this embodiment, the minute flow rate can be adjusted by the gap between the notch portion 24 of the convex portion 21 and the through hole 17, and the minute flow rate can be easily adjusted. Further, by forming the cutouts 24, 24 at equal intervals, the pressure applied to the small valve 18 can be made uniform, and the opening degree of the valve can be stabilized during minute flow rate adjustment.

この実施例によれば微小流量を切欠き部の斜面２５と貫通孔１５との隙間で調整でき、さらには弁棹１３の移動により斜面２５と貫通孔１７との距離が変化するので微小流量の調整ができる。
According to this embodiment, the minute flow rate can be adjusted by the gap between the slope 25 of the notch and the through hole 15, and furthermore, the movement of the valve stem 13 changes the distance between the slope 25 and the through hole 17, so that the minute flow rate can be adjusted. can be adjusted.
本発明によれば大流量給油用の給油ノズルであっても給油レバーの操作で微少流量を密に調整することができる。
