トランスミツシヨン用、あるいはブレーキ用など
の各種のオイルを注入するために用いるノズルに
おいてその液滴下防止構造に関する。[Detailed description of the invention] (Industrial application field) The invention can be used, for example, in automobile assembly lines to produce liquid for window washers, engines, etc.
This invention relates to a structure for preventing liquid dripping in a nozzle used to inject various types of oil for transmissions, brakes, etc.
(従来の技術)
この種のノズルで問題となるのは、液の注入完
了後にノズル内に残つた液滴が、不測に滴下する
事態である。特に、自動車の組立ラインにおいて
は、このようにして滴下した液が他の部品に付着
すると、そのために商品価値が著しく低下する
し、場合によつては、液の浪費も問題となる。(Prior Art) A problem with this type of nozzle is that droplets remaining in the nozzle after the injection of liquid is completed may drip unexpectedly. Particularly on an automobile assembly line, if the liquid dropped in this way adheres to other parts, the value of the product is significantly reduced, and in some cases, wastage of the liquid also becomes a problem.
そのため、従来においては、ノズルにバキユー
ム装置を連通させ、液の注入完了と同時に、ノズ
ル内に残つた液滴を吸引するように構成し、それ
によつて液の滴下を防止するようにしたものが存
在した。 Therefore, in the past, a vacuum device was connected to the nozzle, and the liquid droplets remaining in the nozzle were suctioned at the same time as the injection of the liquid was completed, thereby preventing the liquid from dripping. Were present.
(考案が解決しようとする課題)
しかしながら、この従来構造のものでは、単に
液の滴下を防止するだけのために、かなり大掛か
りなバキユーム装置を必要とし、装置全体が大き
くなつて取扱いが不便なばかりか、コスト高にな
る欠点があつた。(Problem to be solved by the invention) However, with this conventional structure, a fairly large-scale vacuum device is required just to prevent liquid from dripping, making the entire device large and inconvenient to handle. Or, it had the disadvantage of high costs.
本考案は、このような従来欠点を除去しようと
するもので、その目的は、ノズル本来の特性を有
効に利用することにより、特に大掛かりな装置類
を必要とすることなく、簡単な構造で、液の滴下
を防止することのできる液滴下防止構造の提供に
ある。 The present invention aims to eliminate these conventional drawbacks, and its purpose is to effectively utilize the inherent characteristics of the nozzle, without requiring particularly large-scale equipment, and with a simple structure. An object of the present invention is to provide a liquid dripping prevention structure that can prevent liquid from dripping.

で、液の滴下が防止できる。特に、比較的比重の
小さいウオツシヤ液のノズルに対して有効であ
る。(Function) In this way, in the present invention, since the drip prevention member is disposed near the tip of the nozzle, the cross-sectional area of the injection hole becomes smaller near the tip of the nozzle, and the liquid flows at high speed. The ejecting action at that time creates a negative pressure inside the bottomed hollow part of the drip prevention member. When the injection of liquid is stopped, if the above-mentioned drip prevention member is not provided, the liquid remaining at the nozzle tip will fall because only the surface tension on the inner circumferential surface of the nozzle acts. In the idea,
In addition to this, the force due to the negative pressure inside the hollow part whose opening is directed toward the tip of the nozzle is replenished, so that dripping of liquid can be prevented. It is particularly effective for nozzles of washer fluid, which has a relatively low specific gravity.
(考案の効果)
以上の説明から明らかなように、本考案による
ノズルの液滴下防止構造によれば、簡単な構造の
滴下防止部材を付加するだけで、ノズルの有する
特性を有効に利用して液の滴下を防止し得、しか
も、構造が簡単でコストも安くなるので、比較的
比重の小さいウオツシヤ液のノズルに対して効果
が大である。(Effect of the invention) As is clear from the above explanation, according to the nozzle drip prevention structure according to the present invention, the characteristics of the nozzle can be effectively utilized by simply adding a drip prevention member with a simple structure. Since it is possible to prevent the liquid from dripping, and the structure is simple and the cost is low, it is highly effective for nozzles for washing liquid with relatively low specific gravity.
(実施例)
以下、本考案の実施例を図面に基づいて説明す
ると、第3図に示すように、ウインドウオツシヤ
用の液などを収納する加圧タンク1にホース2を
介して電磁式の開閉弁3を有するノズル4が連通
連結されている。このノズル4内の先端部近く、
つまり、ノズル4に形成された断面ほぼ円形の注
入孔5内の先端部近くには、注入孔5の内周面と
は所定間隔をあけて滴下防止部材6が配設されて
いる。(Embodiment) Below, an embodiment of the present invention will be explained based on the drawings. As shown in Fig. 3, an electromagnetic system is connected via a hose 2 to a pressurized tank 1 that stores liquid for window washing, etc. A nozzle 4 having an on-off valve 3 is connected in communication. Near the tip inside this nozzle 4,
That is, the drip prevention member 6 is disposed near the tip of the injection hole 5 formed in the nozzle 4 and having a substantially circular cross section, with a predetermined distance from the inner peripheral surface of the injection hole 5 .
この滴下防止部材6は、第2図に詳しく示すよ

る。 As shown in detail in FIG. 2, this drip prevention member 6 has a circular cross section as a whole, a rounded upper part,
It is formed into a truncated conical shape that gradually tapers toward the lower tip. This truncated cone-shaped drip prevention member 6 has a hollow portion 7a with a bottom that is concentric with the member 6 and opened toward the tapered tip side.
is provided, and a pair of pins 8 are provided protruding from the side opposite to the opening 7b. Then, via this pin 8, the drip prevention member 6 is pulled into the injection hole 5 near the nozzle tip, with the opening 7b directed toward the tip of the nozzle 4, and pulled in by an appropriate distance A from the tip of the nozzle 4. They are installed concentrically with each other.
したがつて、開閉弁3をあけると、タンク1内
の液は、ホース2を通つて、ノズル4の注入孔5

で勢いよく注出され、その高速で注出される液の
エジエクト作用で、前記有底中空部7aに負圧が
発生し該中空部7a内が負圧になる。この場合、
滴下防止部材6が先細りになつているため注出さ

に集まるように注出されるため、ウオツシヤ液用
のタンクなどへの注入を容易に行えるとともに、
中央部へ集まるように注出される液が、中空部7
aを大気から遮断するように作用するため、中空
部7a内が一層確実に負圧に維持される。 Therefore, when the on-off valve 3 is opened, the liquid in the tank 1 passes through the hose 2 and enters the injection hole 5 of the nozzle 4.
The ejecting action of the liquid poured out at high speed generates negative pressure in the bottomed hollow part 7a, causing the hollow part 7a to There is negative pressure inside. in this case,
Since the drip prevention member 6 is tapered, the liquid that is poured out does not spread outward much, but rather gathers in the center, so it can be easily poured into a tank for washing liquid, etc.
The liquid that is poured out so as to collect in the central part flows into the hollow part 7.
Since the hollow portion 7a acts to isolate the space 7a from the atmosphere, the inside of the hollow portion 7a is more reliably maintained at a negative pressure.
そして、開閉弁3を閉じて液の注入を停止する
と、滴下防止部材6が設けられていない場合は、
ノズル4の先端部に残つた液はノズル4内周面で
の表面張力が作用するだけであるので落下してし
まうが、本例の場合では、この表面張力に加え

空部7a内の負圧による力が補充されるので、液
の滴下が防止できる。特に、本例の如く比較的比
重の小さいウオツシヤ液のノズルに対して効果が
大である。また、仮に、液の注入停止時に滴下防

ノズル4の先端より適当距離A引込んでいるた
め、その液は表面張力の作用のみで注入孔5の内
周面と滴下防止部材6の外周面とにわたつて吸着
保持され、滴下が防止されるのである。 Then, when the on-off valve 3 is closed and the injection of liquid is stopped, if the drip prevention member 6 is not provided,
The liquid remaining at the tip of the nozzle 4 falls because only the surface tension on the inner circumferential surface of the nozzle 4 acts, but in this example, in addition to this surface tension, the liquid remaining at the tip of the nozzle 4 Since the force due to the negative pressure in the bottomed hollow portion 7a that opens toward the bottom is replenished, dripping of the liquid can be prevented. This is particularly effective for nozzles that use washer liquid, which has a relatively low specific gravity, as in this example. Furthermore, even if some liquid remains in the injection hole 5 on the upstream side of the drip prevention member 6 when the injection of liquid is stopped, the presence of the drip prevention member 6 at the tip of the nozzle 4 prevents the liquid from remaining. Since the cross section of the injection hole 5 is small and the drip prevention member 6 is retracted a suitable distance A from the tip of the nozzle 4, the liquid is prevented from dripping with the inner peripheral surface of the injection hole 5 only by the action of surface tension. It is adsorbed and held across the outer peripheral surface of the member 6, and dripping is prevented.

ともできる。 In the above embodiment, the drip prevention member 6 is formed into a tapered truncated cone shape, but the shape can be modified in various ways. That is, it may have a simple cylindrical shape, or, contrary to the previous embodiments, it may be formed into a truncated cone shape with a thicker end. Also, when installing the drip prevention member 6, the nozzle 4 is
Alternatively, it may be simply pivoted by the pin 8 without being fixed. Furthermore, it may be fixed to the nozzle 4 by a member other than the pin 8.
