(57) [Abstract] (Correction) [Problem] Since the internal structure of a conventional injector has only a fuel filter on the fuel supply side, and the injector is also installed in an automobile, it is caused by dust due to its safety and properties. The problem of the valve being blown off is a problem. (EN) Provided is a device for preventing dust that has entered or generated inside an injector from going to a valve portion. SOLUTION: A needle part filter 10 that is fixed to the body 6 side of a valve needle shaft 11 part is added to prevent dust from entering the valve 7 part.
Description
本考案は、燃料噴射用インジェクタの品質及び、信頼性向上のため、内部構造の 弁ニードル部に関する技術である。 The present invention relates to a valve needle portion having an internal structure for improving the quality and reliability of a fuel injection injector.
従来の構造は図２のように、フィルタ（１）のみであり、製造中及び使用中に浸 入又は、発生したゴミが、その構造上、弁（７）に挟まり、燃料が止まらない。 この場合、エンジンではコンロッドを突き上げるなどの問題を起こす。 As shown in FIG. 2, the conventional structure is only the filter (1), and the dust that has infiltrated or generated during manufacturing and use is caught in the valve (7) due to its structure, and the fuel does not stop. In this case, the engine causes problems such as pushing up the connecting rod.
インジェクタ内部に浸入又は発生したゴミが、弁（７）部に行くのを未然に防ぐ 内部構造とすること。 Use an internal structure that prevents dust that has entered or generated inside the injector from going to the valve (7).
図１において、弁ニードル（１１）部の、ボデー（６）に固定するフィルタ（１ ０）に類するものを追加し、弁（７）へのゴミの浸入を未然に防ぐ構造とした。 In FIG. 1, a valve needle (11) portion similar to the filter (10) fixed to the body (6) is added to prevent the entry of dust into the valve (7).
図１のインジェクタのタイプは代表的なもので、本考案の実施例である。 The injector type of FIG. 1 is typical and is an embodiment of the present invention.
製品は自動車にも使用されるが、このような二重フィルタとすれば、その品質及 び信頼性が格段に向上し、製造工程においても、弁漏れ問題が減り、製造コスト ダウンは大きな効果である。 The product is also used in automobiles, but if such a double filter is used, its quality and reliability will be greatly improved, valve leakage problems will be reduced in the manufacturing process, and manufacturing costs will be greatly reduced. is there.
