【考案の詳細な説明】
本考案は、たとえば油量調節器などの給油口開閉装置に
関する。[Detailed Description of the Invention] The present invention relates to an oil filler opening/closing device such as an oil amount regulator.
油量調節器において、油量調節は、一般に電磁弁で器体
の内底部の流出孔を開閉することによりて行っている。In oil volume regulators, the oil volume is generally adjusted by opening and closing an outflow hole in the inner bottom of the vessel using a solenoid valve.
そして電磁弁は、そのプランジャを内装したプランジャ
チューブを、油量調節器の器体の流出孔から立設した収
納筒に挿入した状態で取付けられる。The electromagnetic valve is installed by inserting the plunger tube containing the plunger into a storage tube that is erected from the outflow hole of the oil volume regulator body.
また、油量調節器の器体は、亜鉛ダイカスト製品などが
多く、その内面に防錆塗膜をもっている。Additionally, the bodies of oil volume regulators are often made of zinc die-cast products and have anti-rust coatings on their inner surfaces.
この防錆塗膜は、その材料な腐喰から保護する点から不
可欠である。This anti-rust coating is essential to protect the material from corrosion.
ところで、電磁弁のプランジャチューブは、一定の寸法
に切断した後、器体の収納筒に挿入されるが、この組立
時およびその後の修理の挿入のさいにプランジャチュー
ブの切断面は、面取り加工を施したとしても収納筒の内
壁面の防錆皮膜を傷つけてしまう。By the way, the plunger tube of a solenoid valve is cut to a certain size and then inserted into the housing tube of the vessel. During assembly and subsequent insertion for repair, the cut surface of the plunger tube must be chamfered. Even if this is done, it will damage the anti-rust coating on the inner wall of the storage cylinder.
このため防錆皮膜が剥離し、その剥離片が流出孔につま
り、開閉機能がさまたげられる。As a result, the anti-rust coating peels off, and the peeled off pieces clog the outflow hole, interfering with the opening/closing function.
また、この表面処理がないと、品質、とくに製品寿命が
低下するから、防錆皮膜の損傷のない構造が望まれた。In addition, without this surface treatment, quality, especially product life, would be reduced, so a structure without damage to the rust-preventive coating was desired.
また、このような装置では、流出量を調整する場合、流
出孔を径の異なるものに変更する必要があるが、そのた
め電磁弁を取外すと、すなわちプランジャチューブを持
ち上げると、プランジャがその位置に残って脱落してし
まい、その後の組立が面倒となる。In addition, in such devices, when adjusting the outflow amount, it is necessary to change the outflow hole to one with a different diameter, so when the solenoid valve is removed, that is, when the plunger tube is lifted, the plunger remains in that position. This will cause it to fall off, making subsequent reassembly difficult.
本考案は、このような点を改良しようとするもので、防
錆皮膜の損傷をなくし、品質の低下を防止するとともに
、流出孔の調整などに際しての作業を容易に行えるよう
にすることを目的とするものである。The present invention aims to improve these points, and aims to eliminate damage to the anti-rust coating, prevent quality deterioration, and facilitate work such as adjusting outflow holes. That is.
そして、本考案は、器体の内底部の流出孔部から収納筒
を立設するとともに、器体の内面に防錆皮膜を形成し、
上記器体の収納筒内に電磁プランジャ装置のプランジャ
チューブを挿入し、このプランジャチューブ内に上記流

いて、上記プランジャチューブの下端に先細り部を形成
し、この先細り部の内径を上記プランジャの下端の外径
よりも小さく設定したことを特徴とするものである。In addition, the present invention has a storage tube erected from the outflow hole in the inner bottom of the container, and also forms a rust-preventing film on the inner surface of the container.
A plunger tube of an electromagnetic plunger device is inserted into a housing cylinder of the container, and a refueling port opening/closing device is provided with a plunger for opening and closing the outflow hole in the plunger tube, and a tapered portion is formed at the lower end of the plunger tube. , the inner diameter of this tapered portion is set smaller than the outer diameter of the lower end of the plunger.

ーブ７を垂設する。This electromagnetic plunger device 5 includes a hollow-shaped yoke 12.
An electromagnetic coil 6 is installed inside the electromagnetic coil 6, and the upper part of the plunger tube 7 is inserted into the center of the electromagnetic coil 6 by passing through the lower side of the yoke 12, and the pole 11 fitted into the upper part of the plunger tube 7 is inserted into the center of the electromagnetic coil 6. The plunger tube 7 is attached to the upper side of the yoke 12 with a set screw 13, and the plunger tube 7 is suspended from the yoke 12.
そして、プランジャチューブＴ内にプランジャ１０を進

チューブ７の下端で上記弁座体８を当接支持する。Then, the yoke 12 is fixed onto the lid body 4 with the mounting screw 16 screwed onto the container body 3, and the plunger tube 7 is vertically provided through the lid body 4, and inserted into the storage tube 17. Then, with the lid body 4 attached to the vessel body 3, the lower end of the plunger tube 7 abuts and supports the valve seat body 8.
また、上記プランジャチューブＴの下端にはしぼり加工
などによりテーパ状に縮径した先細り部１８を形成し、
この先細り部１８の内径Ｄ１をプランジャ１０の下端の
外径Ｄ２よりも小さく設定する。Further, a tapered portion 18 having a tapered diameter is formed at the lower end of the plunger tube T by squeezing or the like,
The inner diameter D1 of this tapered portion 18 is set smaller than the outer diameter D2 of the lower end of the plunger 10.

ューブの防錆皮膜を損傷することはなく、品質の低下を
防止することができる。According to the present invention, since the tip of the plunger tube is tapered, it is easy to insert the plunger tube into the housing tube, and even when insertion is performed with a small fit tolerance, the tapered portion of the tip of the plunger tube prevents the plunger tube from being inserted. It does not damage the rust film and can prevent quality deterioration.
また、先細り部の内径Ｄ□がプランジャの下端の外径Ｄ

修理の取扱いが容易となる。Also, the inner diameter D□ of the tapered part is the outer diameter D of the lower end of the plunger.
Since the setting is smaller than 2, when the electromagnetic plunger device is removed, the plunger will not come out of the plunger tube, so the parts will not come apart and parts replacement,
Repair handling becomes easier.
