射弁に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic hydrogen gas injection valve used in a hydrogen engine, and more particularly to an electromagnetic hydrogen gas injection valve that performs self-cooling using the hydrogen gas used.
水素ガスを燃料とする火花点火機関については
多数の提案がなされているが、低圧水素ガスを圧
縮行程初期の短期間に所定量だけ供給するように
制御することは難かしく、未だ十分な技術は存し
ない。その理由の１つに、良好な水素ガス噴射弁
が未開発であると云うことがある。 Although many proposals have been made for spark ignition engines that use hydrogen gas as fuel, it is difficult to control the supply of low-pressure hydrogen gas in a predetermined amount during a short period of time at the beginning of the compression stroke, and sufficient technology is still lacking. Does not exist. One of the reasons for this is that good hydrogen gas injection valves have not yet been developed.
一般の燃料噴射弁としては、電磁噴射弁は公知
であるが、水素ガス噴射弁、殊に５Kg／cm2以下の
水素ガスを対象とした低圧水素ガス噴射弁では、
電磁式は殆んどない。 Electromagnetic injection valves are well known as general fuel injection valves, but hydrogen gas injection valves, especially low-pressure hydrogen gas injection valves intended for hydrogen gas of 5 kg/cm 2 or less,
There are almost no electromagnetic types.
水素ガス噴射弁では、次の課題を解決しなけれ

る。 The electromagnetic hydrogen gas injection valve of the present invention has a structure that injects hydrogen gas directly into the cylinder of an engine. Therefore, in addition to the heat generated by the coils, sliding parts, etc., it receives heat transferred from the engine, resulting in a very high temperature.
したがつて、電磁式水素ガス噴射弁は効率よく
冷却される構造となつていなければならないが、
一方では水素ガスが洩れてはならないと云う課題
を併せもつている。 Therefore, the electromagnetic hydrogen gas injection valve must have a structure that allows for efficient cooling.
On the other hand, there is also the issue of preventing hydrogen gas from leaking.
そこで、本発明では、シリンダ内へ供給する水
素ガス自身を冷却媒体として使用することに着目
し、かつシールを静的部分のみとし、動的部分は
全てシリンダ内への連通路としたものである。 Therefore, in the present invention, we focused on using the hydrogen gas itself supplied into the cylinder as a cooling medium, and made the seal only for the static part, and all the dynamic parts were made into communication passages into the cylinder. .
以下、図によつて説明する。 This will be explained below using figures.

A communication path 25 is provided for communicating between the chamber R and the chamber R outside the chamber body.

以上の如く構成された本発明の噴射弁の作用を
以下説明する。 The operation of the injection valve of the present invention constructed as above will be explained below.
コイル５に電流が流れていないときには、ばね
１９が弁ロツド１１を上方へ押し上げ、弁１７が
弁開口１６を閉じている。 When no current is flowing through the coil 5, the spring 19 pushes the valve rod 11 upwards and the valve 17 closes the valve opening 16.
今、コイル５に電流が流れると、コイル５が励
磁され、アーマチユアプランジヤ７を下方へ押し

される。コイル５への電流が遮断されると、ばね
１９が弁ロツド１１を上方へ押し上げ、弁１７は
弁開口１６を閉じ、水素ガスの噴射が終了する。 Now, when current flows through the coil 5, the coil 5 is excited and pushes the armature plunger 7 downward. Then, the intermediate rod 10 is pushed down via the push rod 8, and the valve rod 11 is pushed down against the spring 19. Valve 17 therefore opens valve opening 16. Then, the hydrogen gas in the hydrogen gas reservoir 13 is injected into the cylinder as indicated by arrow P in the figure. When the current to the coil 5 is cut off, the spring 19 pushes the valve rod 11 upward, the valve 17 closes the valve opening 16, and the injection of hydrogen gas ends.
さて、本発明の電磁式水素噴射弁はシリンダ内
へ直接挿入保持されるものである。そして、少く
とも弁１７及び弁開口１６が図示しない内燃機関
のシリンダ内で高温ガスにさらされている。 Now, the electromagnetic hydrogen injection valve of the present invention is directly inserted and held into a cylinder. At least the valve 17 and the valve opening 16 are exposed to high-temperature gas within a cylinder of an internal combustion engine (not shown).
さらに、１分間に最高6000回転位行われるの
で、摺動部から大量の熱が発生する。 Furthermore, since the rotation is performed at a maximum of 6,000 revolutions per minute, a large amount of heat is generated from the sliding parts.
又、コイル５からの発熱もある。 Also, heat is generated from the coil 5.
よつて、弁ケーシング１内には大量の熱が発
生、伝導流入し、これによつて各部の耐久性を低
下させ、ひいては高速応答性の低下、シール性の
低下を招くものとなる恐れがあるが、本発明で
は、次のように、弁ケーシング１内を水素ガスで
冷却するので、それらの欠点をなくすことができ
る。 Therefore, a large amount of heat is generated and conducted into the valve casing 1, which reduces the durability of each part, and may even lead to a decrease in high-speed response and a decrease in sealing performance. However, in the present invention, since the inside of the valve casing 1 is cooled with hydrogen gas as described below, these drawbacks can be eliminated.
水素ガスはコネクタパイプ２１を通つて供給口
２０からアーマチユアプランジヤ７の凹所２６へ
導入されている。次いで、連通路２２，２３，２
４を通つて室Ｒへ入り、さらに連通路２５を介し
て水素ガス溜り１３へ入る。これらの流動時に熱
を吸収する。 Hydrogen gas is introduced into the recess 26 of the armature plunger 7 from the supply port 20 through the connector pipe 21. Next, the communication paths 22, 23, 2
4 into the chamber R, and further into the hydrogen gas reservoir 13 via the communication path 25. They absorb heat as they flow.
以上の如く構成され、作用する本発明の効果は
次のとおりである。 The effects of the present invention, which is constructed and operated as described above, are as follows.
水素ガスの熱伝導率は空気の７〜８倍である。
したがつて、空冷式と比べて冷却効率が高い。 The thermal conductivity of hydrogen gas is 7 to 8 times that of air.
Therefore, the cooling efficiency is higher than that of an air-cooled type.
燃焼用に使用される水素ガスをそのまま冷却に
使用するので、装置が複雑とならず又、熱損失が
低下する。 Since the hydrogen gas used for combustion is directly used for cooling, the device is not complicated and heat loss is reduced.
水素ガスを弁ケーシングの一端から他端へ貫通
流動させるので、弁ケーシング内の熱を全体的に
うばうことができ、一個所に熱が集中することが
ない。 Since the hydrogen gas is made to flow through the valve casing from one end to the other, the heat within the valve casing can be completely dissipated, and the heat is not concentrated in one place.
発熱個所、及び熱伝導面の付近を必らず水素ガ
スが流動するので、熱吸収の能率がよい。 Since hydrogen gas always flows near the heat-generating area and the heat-conducting surface, heat absorption efficiency is high.
可動部或いは摺動部を介して水素ガスが洩れた
としても、可動部或いは摺動部が常に水素ガス流
通路の内側にあるので、洩れた水素ガスは常に流
通路に封じ込まれるものとなつている。 Even if hydrogen gas leaks through the moving part or sliding part, the moving part or sliding part is always inside the hydrogen gas flow path, so the leaked hydrogen gas will always be confined in the flow path. ing.
シールＳが設けられているのが、全て静止部材
間であり、シール性が向上する。 Seals S are provided between all stationary members, improving sealing performance.
冷却性の向上により耐久性及び信頼性が向上す
る。 Improved cooling performance improves durability and reliability.
