この考案は、ガスの噴出流量を2段階に分けて調整でき
るようにしたガスライターの流量調整装置において、流
量調整手段が注入弁を兼ねている流量調整装置に関する
ものである。[Detailed description of the invention] This invention relates to a flow rate adjustment device for a gas lighter that can adjust the gas ejection flow rate in two stages, in which the flow rate adjustment means also serves as an injection valve. be.
ライターの着火時の安全性を向上させるためには、流量
を一定の範囲内でのみ調整可能とし、生ガスの噴出ある
いは過大流出による異常燃焼、過大炎の発生を防止する
必要がある。In order to improve safety when igniting a lighter, it is necessary to make the flow rate adjustable only within a certain range to prevent abnormal combustion and excessive flames due to ejection or excessive outflow of raw gas.
ところが、ガスの気化が促進される高温条件下でライタ
ーを使用する場合にはその流量調整範囲を標準的なもの
より小流量域に変更しなければ過大炎が形成されるおそ
れがあり、逆に、ガスの気化が抑制される低温条件下で
ライターを使用する場合には流量調整範囲を大流量域に
変更しなければ着火不良等の不都合が生じる。However, when using a lighter under high-temperature conditions where gas vaporization is promoted, unless the flow rate adjustment range is changed to a lower flow rate range than the standard one, an excessive flame may be formed; When using a lighter under low temperature conditions where gas vaporization is suppressed, problems such as ignition failure may occur unless the flow rate adjustment range is changed to a large flow rate range.
したがって、ライターを使用する場合は、使用される条
件を考慮して流量調整範囲をあらかじめ調整し、異常燃
焼、過大炎等の危険性および着火不良等の不都合を予防
するのが好ましいのであるが、この調整範囲の変更を行
うためには従来はライターを分解する必要があるために
、危険性あるいは性能低下等を了承したうえでそのまま
使用しているのが現状である。Therefore, when using a lighter, it is preferable to adjust the flow rate adjustment range in advance in consideration of the conditions in which it will be used to prevent risks such as abnormal combustion and excessive flame, and inconveniences such as poor ignition. Conventionally, it is necessary to disassemble the lighter in order to change the adjustment range, so the current situation is that lighters are used as is, with the understanding that they may be dangerous or degrade in performance.
そこで、ライターの使用環境に適合する第1段階の流量
調整と該第1段階の調整範囲内において日々の使用条件
に対応する第2段階の流量調整とを行い得るようにした
ガスライター用の流量調整装置が提案され実用化されて
いる。Therefore, the flow rate for gas lighters is designed to be able to perform a first stage flow rate adjustment that matches the usage environment of the lighter, and a second stage flow rate adjustment that corresponds to daily usage conditions within the first stage adjustment range. A regulating device has been proposed and put into practical use.
更にか・る2段階の流量調整を行うようにした流量調整
装置において、第1若しくは第2段階のいずれかの調整
手段(通常は第1段階の調整手段)に注入弁を兼用させ
るようにした構造を有する流量調整装置が提案されてい
る。Furthermore, in such a flow rate regulating device that performs two-stage flow rate adjustment, either the first or second stage regulating means (usually the first stage regulating means) also serves as an injection valve. A flow regulating device having a structure has been proposed.
ところで、か・る注入弁を兼ねる流量調整手段を有する
流量調整装置にあっては、注入弁を常時閉弁方向へ付勢
しておく必要上、注入弁を兼ねる調整手段にスプリング
の張力が、相対的に螺動する調整ネジと調整筒体との間
で担持されてスプリングの張力が両者の螺合部に作用し
ているために、注入弁を兼ねる調整手段で調整ネジを回
転させようとするとき、しばしば調整ネジの回転に随伴
して調整筒体が回転してしまい、流量調整範囲の変更を
正確に行い得ない欠点があった。By the way, in a flow rate adjustment device having a flow rate adjustment means that also serves as an injection valve, since it is necessary to always bias the injection valve in the valve closing direction, the tension of the spring is applied to the adjustment means that also serves as the injection valve. Since the tension of the spring is supported between the adjusting screw and the adjusting barrel that screw relative to each other and is acting on the screwed part of the two, it is difficult to rotate the adjusting screw with the adjusting means that also serves as an injection valve. When doing so, the adjustment barrel often rotates with the rotation of the adjustment screw, making it impossible to accurately change the flow rate adjustment range.

を達成するように構成している。Reference numeral 9 denotes an injection valve rod inserted into the flow rate adjustment cylinder 6 so as to be able to freely move and rotate in the axial direction, and is seated on a valve seat 10 formed on the inner peripheral surface of the flow rate adjustment cylinder 6. The gasket 11 is attached, and the gasket 1 is tightened by the tension of the spring 12 stretched between the cap portion 6a and the injection valve rod 9.
1 is crimped and held on the valve seat 10 to achieve the same injection valve function as the conventional one.

を流量調整筒6の下端近傍部に位置させている。Furthermore, a flat plate-shaped protrusion 9a is provided at the upper end of the injection valve rod 9 constituting the injection valve in this way, and a slit 5a is provided at the lower end of the flow rate adjustment screw 5, and the protrusion 9a is inserted into the slit. ) The relative movement between the injection valve rod 9 and the flow rate adjustment screw 5 is restrained only in the rotational direction by engaging the injection valve rod 9 and the flow rate adjustment screw 5 to connect them, and the lower end of the valve rod 9 is used to adjust the flow rate. It is located near the lower end of the cylinder 6.

いる。13 is a notch for operation provided on the lower end surface of the flow rate adjustment cylinder 6;
15 is a notch for operation provided on the lower end surface of the injection valve rod 9; 15 is a stopper provided between the lower end surface of the cylinder body 2 and the inner bottom surface of the case 7; It is formed integrally with the surface and restricts its rotation range.
斯る構造を有する流量調整装置において、ケース7の底
面から爪等で流量調整筒6を回転させると、この回転に
ともなって流量調整筒6が筒体2の内部を螺進退し、流
量調整筒6の上端部に螺着した流量調整ねじ5を昇降さ
せて流量調整部材3への圧縮量を変更し、ガスの噴出流
量を変える。In the flow rate adjustment device having such a structure, when the flow rate adjustment tube 6 is rotated with a claw or the like from the bottom of the case 7, the flow rate adjustment tube 6 is screwed back and forth inside the tube body 2 with this rotation, and the flow rate adjustment tube 6 is rotated. The amount of compression applied to the flow rate adjustment member 3 is changed by raising and lowering a flow rate adjustment screw 5 screwed onto the upper end of the gas flow rate adjustment member 6, thereby changing the amount of gas ejected.
通常の調整は、この流量調整筒6による調整で充分であ
るが、流量調整筒6による調整範囲を越えて調整しよう
とする場合は、小型のドライバー、あるいは専用工具等
を用いて注入弁杆9を回転させる。For normal adjustment, adjustment using this flow rate adjustment tube 6 is sufficient, but if you wish to make adjustments beyond the adjustment range of the flow rate adjustment tube 6, use a small screwdriver or special tool to tighten the injection valve rod 9. Rotate.
このとき、注入弁杆9を閉弁方向へ付勢しているスプリ
ング12の張力は、注入弁杆9と流量調整筒6との間に
作用しており、従来のように、注入弁杆9と流量調整ネ
ジ5との間には作用していない。At this time, the tension of the spring 12 that urges the injection valve rod 9 in the valve closing direction is acting between the injection valve rod 9 and the flow rate adjustment tube 6, and as in the conventional case, the tension of the spring 12 is biased toward the valve closing direction. and the flow rate adjustment screw 5.
すなわち、スプリング12の張力は、流量調整筒6を介
して流量調整筒6と筒体2との螺合部に作用し、両者の
ネジ間隙を消失させて摩擦接触力をそこに発生させてい
るために、注入弁杆9を回転させても流量調整筒6がこ
れに随伴して回転してしまうおそれがなくなる。That is, the tension of the spring 12 acts on the threaded portion of the flow rate adjustment tube 6 and the cylinder body 2 via the flow rate adjustment tube 6, eliminating the screw gap between the two and generating frictional contact force there. Therefore, even if the injection valve rod 9 is rotated, there is no fear that the flow rate adjustment cylinder 6 will rotate accordingly.
これに反し流量調整ネジ5にはスプリング12の張力が
全く作用していないので注入弁杆9の回転により流量調
整ネジ5はスムースに回転し、所望の範囲の流量調整を
行うことが出来るのである。On the other hand, since the tension of the spring 12 is not acting on the flow rate adjustment screw 5 at all, the flow rate adjustment screw 5 rotates smoothly by rotation of the injection valve rod 9, and the flow rate can be adjusted within a desired range. .
このように、注入弁杆9の回転にともなって流量調整ね
じ5が回転し、流量調整筒6からの突出量を変更させる
ので流量調整部材3への圧縮量が変更されガスの噴出流
量が変る。In this way, as the injection valve rod 9 rotates, the flow rate adjustment screw 5 rotates and changes the amount of protrusion from the flow rate adjustment tube 6, thereby changing the amount of compression to the flow rate adjustment member 3 and changing the gas jet flow rate. .
したがって、このようにして注入弁杆9のみの回転によ
って調整範囲を変更すれば、ライターの使用条件に適合
した調整範囲を得ることができる。Therefore, by changing the adjustment range by rotating only the injection valve rod 9 in this way, it is possible to obtain an adjustment range that is suitable for the usage conditions of the lighter.
なお、燃料タンク1にガスを充填すべくガスボンベの注
入口を注入弁杆9の下端部に圧着すれば、スプリング1
2の張力に抗して注入弁杆9が一点鎖線で示すように移
動しガスケット11が流量調整筒6の下面に当接して来

したガスケット11は、流量調整筒6の下面に当接して
移動を阻止される結果、注入弁杆9の注入弁孔がガスケ
ツトまりも上方へ移動して開孔されるので従来と同様に
してガスを燃料タンク1内に注入することが出来る。In addition, if the injection port of the gas cylinder is crimped to the lower end of the injection valve rod 9 in order to fill the fuel tank 1 with gas, the spring 1
2, the injection valve rod 9 moves as shown by the dashed line, and the gasket 11 comes into contact with the lower surface of the flow rate adjustment tube 6, so that when the injection valve rod 9 is pushed further, it rises from the valve seat 10. The gasket 11 is prevented from moving by coming into contact with the lower surface of the flow rate adjustment tube 6, and as a result, the injection valve hole of the injection valve rod 9 moves upwards and is opened, so that the gas can be injected into the fuel in the same manner as in the past. It can be injected into the tank 1.
このとき、注入弁杆9と流量調整ねじ5とは軸方向の相
対的な移動を自在にして連結されているので、ガスの充
填に支障をもたらすおそれが、ない。At this time, since the injection valve rod 9 and the flow rate adjustment screw 5 are connected to each other so as to be able to move freely in the axial direction, there is no possibility that gas filling will be hindered.
また注入弁部等に異物が進入し、あるいは流量調整筒6
が不用意に回転してガスの噴出流量が不用意に変ること
を防止するために調整孔8に開閉蓋またはキャップ等を
装着してもよい。Also, foreign matter may enter the injection valve, etc., or the flow rate adjustment cylinder 6
An opening/closing lid, a cap, or the like may be attached to the adjustment hole 8 in order to prevent the adjustment hole 8 from rotating inadvertently and causing the gas ejection flow rate to change inadvertently.
以上説明したように、この考案に係る流量調整装置によ
れば、注入弁杆9を開弁方向へ常時付勢しているスプリ
ング12を、注入弁杆9と流量調整筒6との間に張設し
、従来のように流量調整ネジ5との間には張設していな
いので、スプリング12の張力が流量調整ネジ5と流量
調整筒6との螺合部に作用するようなおそれがない。As explained above, according to the flow rate adjustment device according to this invention, the spring 12 that constantly biases the injection valve rod 9 in the valve opening direction is tensioned between the injection valve rod 9 and the flow rate adjustment cylinder 6. Since it is not tensioned between the flow rate adjustment screw 5 and the flow rate adjustment screw 5 as in the conventional case, there is no fear that the tension of the spring 12 will act on the threaded portion between the flow rate adjustment screw 5 and the flow rate adjustment cylinder 6. .
このため、注入弁杆9により流量調整ネジ5を回動する
とき、これに随伴して流量調整筒6が回転してしまい、
実際上注入弁杆9を利用しての流量調整範囲の変更が不
可能となってしまうようなおそれがなく、流量調整ネジ
5のみを独立してスムースに回転させて軸方向に上下動
させ、調整範囲の変更を行うことが出来るので゛ある。Therefore, when the flow rate adjustment screw 5 is rotated by the injection valve rod 9, the flow rate adjustment cylinder 6 rotates accordingly.
In practice, there is no fear that the flow rate adjustment range cannot be changed using the injection valve rod 9, and only the flow rate adjustment screw 5 can be independently and smoothly rotated to move up and down in the axial direction. This is because the adjustment range can be changed.
