Description

本発明は、エンジンの回転に連動したピストンの動きに合わせて燃料を供給する高速開閉複座弁装置に関する。即ち、本発明は、特に、新規な構造と機構を有する、精密で、誤作動のない燃料供給のための高速開閉弁装置に関する。   The present invention relates to a high-speed opening / closing double seat valve device that supplies fuel in accordance with the movement of a piston interlocked with the rotation of an engine. That is, the present invention particularly relates to a high-speed on-off valve device for supplying fuel that has a novel structure and mechanism and is precise and does not malfunction.

従来の高速開閉弁装置では、開閉部分は、単座弁（シングル弁）方式であり（特許文献１参照）、供給圧力の一次側とエンジンに流れ込む二次側の圧力差（差圧）がそのまま単座弁の流体通過面積に加わる押しつけ力となるために、弁を開く方向への負担は大きく、また、燃料の通過面積も限定される。特に、駆動力が小さいソレノイド駆動の場合には、差圧を小さくせざるを得ないために、結果的に一次側の供給圧力を低く、流量も少なくなるので、エンジンの性能にも影響する。即ち、従来の高速開閉弁装置では、燃料の通過面積が少なく、供給圧力も低く、能力が限定される。   In the conventional high-speed on-off valve device, the open / close portion is a single seat valve (single valve) system (see Patent Document 1), and the pressure difference (differential pressure) between the primary side of the supply pressure and the secondary side flowing into the engine is directly single seated. Since this is a pressing force applied to the fluid passage area of the valve, the load in the direction of opening the valve is large, and the fuel passage area is also limited. In particular, in the case of solenoid driving with a small driving force, the differential pressure must be reduced. As a result, the supply pressure on the primary side is reduced and the flow rate is reduced, which also affects the performance of the engine. That is, in the conventional high-speed on-off valve device, the fuel passage area is small, the supply pressure is low, and the capacity is limited.

図１は、この従来技術の高速開閉装置を説明する側断面図である。燃料流体は、矢印で示すように流れ、入口５から入り、弁が開いている状態で示す図1のように、出口６に流れる。インナー弁３と弁座４の間が図１のようにソレノイド１０に電流が流れる状態では、可動鉄片（アーマチュア）２が引き付けられて、インナー弁３と弁座４の間に隙間が形成され、流れ孔が開いている。ソレノイドに電流が流れていない状態では、可動鉄片２は引き上げられていなく、それらの重量と戻りばね１１により、インナー弁３は、弁座４に密着するように押し付けられて、流体の通過は阻止されている。次に、図１のようにソレノイド１０に電流が流れると、鉄片２が引き付けられて、流路が図示のように開く。即ち、インナー弁３は上下に並進運動をして、インナー弁３と弁座４との間に隙間１２が生じると、そこに、３と１２と４２を通じる通路２４ができ、流体の流れが開く、そして、電流が切られると、インナー弁３は弁座４の上に落ち、密着し、流体の流れは阻止される。それの繰り返しにより、弁が開閉し、流体が流れる。この従来の高速開閉弁装置では、弁部分１は単一であり、通路の面積も制限されたものである。
これに対して、本発明は、インナー弁と弁座の組合せを倍の２個即ち、１対にした複座弁を提案するものである。
特許第２７７１１１５号公報 特開平７−８３１３８号公報 FIG. 1 is a side sectional view for explaining this conventional high-speed switchgear. The fuel fluid flows as indicated by the arrow, enters from the inlet 5 and flows to the outlet 6 as shown in FIG. 1 with the valve open. In the state where the current flows through the solenoid 10 between the inner valve 3 and the valve seat 4 as shown in FIG. 1, the movable iron piece (armature) 2 is attracted to form a gap between the inner valve 3 and the valve seat 4, The flow hole is open. In the state where no current flows through the solenoid, the movable iron piece 2 is not pulled up, and the inner valve 3 is pressed against the valve seat 4 by their weight and the return spring 11 to prevent passage of fluid. Has been. Next, when a current flows through the solenoid 10 as shown in FIG. 1, the iron piece 2 is attracted and the flow path opens as shown. That is, the inner valve 3 translates up and down, and when a gap 12 is formed between the inner valve 3 and the valve seat 4, a passage 24 is formed through the three, 12 and 42, and the flow of fluid is reduced. When opened and the current is turned off, the inner valve 3 falls on the valve seat 4 and is in close contact with the fluid flow. By repeating this, the valve opens and closes and fluid flows. In this conventional high-speed on-off valve device, the valve portion 1 is single and the area of the passage is limited.
On the other hand, the present invention proposes a double seat valve in which the combination of the inner valve and the valve seat is doubled, that is, a pair.

本発明の流体高速開閉弁は、以上のように、閉止時の流体漏洩が少なくし、部品加工及び組立ての上での、難しい精度と仕上げを可能にし、組立て時の調整を容易なものにした高速開閉複座弁を提供する。   As described above, the fluid high-speed on-off valve of the present invention has less fluid leakage at the time of closing, enables difficult precision and finishing in parts processing and assembly, and makes adjustment during assembly easy. Provides high-speed open / close double seat valves.

更に、本発明の流体高速開閉弁により、次のような技術的効果が得られた。
第１に、本発明の複座弁方式では、上部の弁体と下部の弁体と有し、上下の２つの弁を通過するので、燃料の通過面積を大きくとることができ、また、上部弁体には一次側の供給圧力により弁を開く方向に圧力を受け、下部弁体では閉まる方向に圧力を受けるために、その圧力バランスは、賦勢機の駆動力を助け、よりおおきな供給圧力を使用することができる。そのために、高性能で低価格な高速開閉弁装置が得られる。
第２に、上下の２つの弁体の弁間距離を、調整可能にしてあるので、精密な組立て、加工ができる。
第３に、下部の弁座が接触する支持体部分との間に弾性体を使用しており、上下弁の寸法誤差を調整する機構を有する。その誤差調整可能の寸法は、
０．数ミリである。
第４に、本発明の高速開閉弁装置を採用すると、エンジンに吹き込まれる燃料量が増加し、同一排気量で高出力が可能になり、そして、燃料量の調整範囲が広がることなど、エンジンの設計にも自由度が大きくなり、クリーンで高性能のエンジンが可能になる。
第５に、前記の弾性体、例えば、Ｏリングを採用することにより、下部弁座と下部インナー弁が確実に接触するために、漏洩をほぼ完全に無くすことができる高速開閉弁装置が提供できる。 Furthermore, the following technical effects were obtained by the fluid high-speed on-off valve of the present invention.
1stly, in the double seat valve system of this invention, it has an upper valve body and a lower valve body, and since it passes two upper and lower valves, the passage area of a fuel can be taken large, Since the valve body receives pressure in the direction of opening the valve by the supply pressure on the primary side, and the lower valve body receives pressure in the closing direction, the pressure balance helps the driving force of the energizer, and the larger supply pressure Can be used. Therefore, a high-performance and low-cost high-speed on-off valve device is obtained.
Second, since the distance between the upper and lower two valve bodies can be adjusted, precise assembly and processing can be performed.
Thirdly, an elastic body is used between the lower portion and the support portion that contacts the valve seat, and a mechanism for adjusting the dimensional error of the upper and lower valves is provided. The error adjustable dimensions are
0. A few millimeters.
Fourth, when the high-speed on-off valve device of the present invention is adopted, the amount of fuel injected into the engine increases, high output can be achieved with the same displacement, and the adjustment range of the fuel amount is expanded. The design is also more flexible and a clean and high performance engine is possible.
Fifth, by adopting the elastic body, for example, an O-ring, the lower valve seat and the lower inner valve are in reliable contact with each other, so that it is possible to provide a high-speed on-off valve device that can eliminate leakage almost completely. .

本発明の流体燃料供給のための高速な開閉弁装置は、インナー弁及び弁座の組（弁体）を倍にしたことにより、流量が上がるだけでなく、２つの弁部分の各々には、逆方向に流れの圧力を受け、即ち、上部弁体には、一次側の供給圧力により弁部を開く方向に圧力を受け、下部弁体では閉まる方向に圧力を受けるために、その圧力バランスは、賦勢機の駆動力を助け、よりおおきな供給圧力を使用することができる。そのために、高性能でも低価格な高速開閉弁装置が得られる。以下、その説明を図２により行う。   The high-speed on-off valve device for supplying fluid fuel according to the present invention not only increases the flow rate by doubling the combination of the inner valve and the valve seat (valve element), but each of the two valve portions includes: The flow balance is received in the opposite direction, i.e., the upper valve body receives pressure in the direction of opening the valve portion by the primary supply pressure, and the lower valve body receives pressure in the closing direction. , Help the drive power of the energizer, and use a greater supply pressure. For this reason, a high-speed opening / closing valve device with high performance and low cost can be obtained. This will be described below with reference to FIG.

ここで、賦勢機とは、弁部分に往復運動を与えるものであり、以下、ソレノイドで説明するが、その他にその動力源としては、電気、電子、油圧、空圧、その他である。例えば、空気圧駆動による振動発生機、モータ駆動で往復運動を与える機構、電子式振動機なども場合により、使用することができる。   Here, the urging machine gives a reciprocating motion to the valve portion, and will be described below as a solenoid, but other power sources include electricity, electronics, hydraulic pressure, pneumatic pressure, and the like. For example, a pneumatic vibration generator, a motor-driven reciprocating mechanism, an electronic vibrator, and the like can be used in some cases.

以下、図２〜４を参照して、本発明の流体高速開閉複座弁を説明するが、本発明はそれに限定されないものである。以下、気体燃料を例にして説明するが、他の流体も供給できる弁でも同様である。
図２は、本発明の高速開閉弁装置の側断面を弁の閉じた状態（Ａ図）と弁の開いた状態（Ｂ図）で示す各側断面図である。 Hereinafter, although the fluid high-speed opening / closing double seat valve of this invention is demonstrated with reference to FIGS. 2-4, this invention is not limited to it. Hereinafter, although gaseous fuel is demonstrated as an example, it is the same also with the valve which can supply another fluid.
FIG. 2 is a side sectional view showing a side section of the high-speed on-off valve device of the present invention in a state where the valve is closed (FIG. A) and a state where the valve is opened (FIG. B).

即ち、本発明による1対の弁部分１は、図示のように、上下に連結した一対の弁体（３、４）（１３、１４）よりなり、その２つの上部及び下部弁体（３、４）（１３、１４）の間に流体燃料の入口５が設けられる。そして、流体の出口６は、図２Ｂに、より明確に示されるように、矢印で示す流体の流れが、上部弁体（３、４）を通過した流れは、側路７を通り、下部弁体（１３、１４）を通過した流れと一緒になり、６から出る。   That is, a pair of valve portions 1 according to the present invention is composed of a pair of upper and lower valve bodies (3, 4) (13, 14) connected to each other as shown in the figure, and the two upper and lower valve bodies (3, 4) Fluid fuel inlet 5 is provided between (13, 14). As shown more clearly in FIG. 2B, the fluid outlet 6 is such that the flow of the fluid indicated by the arrow passes through the upper valve body (3, 4), passes through the side passage 7, passes through the lower valve. Together with the flow that passed through the body (13, 14), it exits from 6.

即ち、弁部分１は、２つの並列した弁体からなり、各々の弁体は、インナー弁３、１３と弁座４、１４とのカップルであり、即ち、各々、互いに向き合ったインナー弁（３、１３）と弁座（１３、１４）を有し、インナー弁（３、１３）は、閉鎖位置から、決められた距離（ａ或いはｂ）だけ離れるように並進可能である。
図２Ａは、閉鎖位置の状態を表し、ソレノイド１０には電流が流れていない状態であり、可動鉄片（アーマチュア）２は引き付けられていなく、その重量と戻りばね（１１）により引き下げられている。すると、上部インナー弁３は、弁座４に押し付けられており、それと結合されている下部インナー弁１３も引き下げられ、弁座１４に押し付けられ、密着している。そのために、各々、インナー弁と弁座との間には隙間がなく、流体の通過は阻止されている。 That is, the valve portion 1 is composed of two parallel valve bodies, and each valve body is a couple of the inner valves 3 and 13 and the valve seats 4 and 14, that is, the inner valves (3 13) and the valve seat (13, 14), and the inner valve (3, 13) is translatable away from the closed position by a predetermined distance (a or b).
FIG. 2A shows the state of the closed position, in which no current flows through the solenoid 10, and the movable iron piece (armature) 2 is not attracted but is pulled down by its weight and the return spring (11). Then, the upper inner valve 3 is pressed against the valve seat 4, and the lower inner valve 13 coupled thereto is also lowered, pressed against the valve seat 14, and is in close contact therewith. For this reason, there is no gap between the inner valve and the valve seat, and the passage of fluid is blocked.

図２Ｂは、開放位置の状態を表し、ソレノイド１０には電流が流れている状態であり、可動鉄片（アーマチュア）２は引き付けられている。すると、上部インナー弁３は、ａの距離、引き上がり、弁座４から離れており、それを結合されている下部インナー弁１３もｂだけ引き上げられ、弁座１４から離れる。すると、各々、インナー弁３、１３と弁座４と１４との間に隙間１２が形成され、図示の矢印のように、流体が流れる。   FIG. 2B shows a state of the open position, in which a current flows through the solenoid 10 and the movable iron piece (armature) 2 is attracted. Then, the upper inner valve 3 is lifted by the distance a, and is separated from the valve seat 4, and the lower inner valve 13 coupled thereto is also lifted by b and separated from the valve seat 14. Then, gaps 12 are formed between the inner valves 3 and 13 and the valve seats 4 and 14, respectively, and fluid flows as shown by the arrows in the figure.

通常、通電時にインナー弁と弁座の間には、０．７〜０．３ｍｍの隙間が形成され、そこを流体が通過する。
従って、アーマチュア２と上部インナー弁３と下部インナー弁１３は、一体で並進運動する。そのために、それらの間は結合されているように、精密に組立てなければならない。しかも、精度よく組立てなければ、閉止時の流体漏洩が多くなる。そのために、上下各々のインナー弁（３、１３）と弁座（４、１４）とを精度よく組み合わせることが重要である。この目的を達するために、上部インナー弁３とインナー弁１３の間にその距離調整のために、図示のように、すきま調整材８、例えば、皿ばねを設ける。皿ばねは、皿を２つ互いに向き合って合わせた構造であり、上下の距離を弾力的に調整することができるものである。ねじを締め付けることにより、すきま調整材即ち、皿ばねを押し付けて、皿ばねの弾力分隙間調整することができる。 Usually, a gap of 0.7 to 0.3 mm is formed between the inner valve and the valve seat when energized, and the fluid passes therethrough.
Therefore, the armature 2, the upper inner valve 3, and the lower inner valve 13 translate together. Therefore, it must be assembled precisely so that they are connected. In addition, if it is not assembled accurately, fluid leakage at the time of closing increases. Therefore, it is important to combine the upper and lower inner valves (3, 13) and the valve seats (4, 14) with high accuracy. In order to achieve this purpose, a clearance adjusting member 8, for example, a disc spring, is provided between the upper inner valve 3 and the inner valve 13 for adjusting the distance as shown in the figure. The disc spring has a structure in which two discs face each other and can adjust the vertical distance elastically. By tightening the screw, the gap adjusting member, that is, the disc spring, can be pressed to adjust the gap by the elasticity of the disc spring.

更に、組み立ての精度を容易に向上できるように、下部弁座１４と支持体１５の間の調整のために、即ち、支持体１５と弁部分１との間の調整のために、即ち、設定誤差が、自動的に調整されるように、緩衝用隙間を作り、弾性材９をそこに設ける。すると、上部及び下部インナー弁が閉止になるときに、下部インナー弁１３が先に下部弁座１４と接触し、流体が閉止しながら、下部弁座裏面の隙間、０．数ミリだけ動いて、上部インナー弁３と上部弁座４が確実に接触して、流体の閉止する動きを確実にできる。   Furthermore, in order to be able to easily improve the accuracy of the assembly, for adjustment between the lower valve seat 14 and the support body 15, i.e. for adjustment between the support body 15 and the valve part 1, ie setting. A buffering gap is made so that the error is automatically adjusted, and the elastic material 9 is provided there. Then, when the upper and lower inner valves are closed, the lower inner valve 13 comes into contact with the lower valve seat 14 first, and the fluid closes, while the clearance between the lower valve seat back surface, 0. By moving only a few millimeters, the upper inner valve 3 and the upper valve seat 4 are reliably in contact with each other, and the movement of closing the fluid can be ensured.

図２Ａ、Ｂの高速開閉弁装置では、流体は、各々のインナー弁３、１３と弁座４、１４の間に形成される隙間１２を通過して、図示のような矢印に従って、流れる。この図では、分かり易いように、弁座４、１４の中に通過孔４２が大きく図示してあるが、通常、閉鎖状態での漏洩を防止するためには、はるかに小さい孔しか開けることができない。
然しながら、流体の流量を更に大きくするために、図３の一部断面図に示すように、各インナー弁３、１３と弁座４、１４に、流体通過孔或いは溝３２、４２を設けることができる。ここでは、インナー弁３、１３には、適宜配置された流体通過孔３２（図示のように複数でも単数でもよい）を設け、それと向き合う弁座４、１４には、インナー弁の通過孔３２と向き合っては、通過孔或いは溝は設けなく、即ち、配置された閉鎖領域４３を有する。このように孔或いは溝３２、４２を配置すると、図示のように、閉鎖位置においては、インナー弁と弁座の間には、開放領域なく、即ち、流体通過がない構成である。但し、図３では、閉止時でなく、インナー弁と弁座の間に隙間が形成された開放時の状態を示す。図３では、賦勢機即ち、ソレノイドコア１０は、半分しか示されていない。 2A and 2B, the fluid flows through the gaps 12 formed between the inner valves 3 and 13 and the valve seats 4 and 14 according to the arrows as shown. In this figure, the passage hole 42 is shown large in the valve seats 4 and 14 for easy understanding. However, in order to prevent leakage in the closed state, it is usually possible to open a much smaller hole. Can not.
However, in order to further increase the flow rate of the fluid, as shown in the partial cross-sectional view of FIG. 3, each of the inner valves 3 and 13 and the valve seats 4 and 14 may be provided with fluid passage holes or grooves 32 and 42. it can. Here, the inner valves 3 and 13 are provided with fluid passage holes 32 (a plurality or a single number as shown in the figure) that are appropriately arranged, and the valve seats 4 and 14 facing the inner passages 3 and 13 are connected to the passage holes 32 of the inner valve. Facing each other, there are no passage holes or grooves, i.e. having a closed region 43 arranged. When the holes or grooves 32 and 42 are arranged in this way, as shown in the figure, in the closed position, there is no open region, that is, no fluid passage between the inner valve and the valve seat. However, FIG. 3 shows a state in which the gap is formed between the inner valve and the valve seat, not in the closed state. In FIG. 3, only half of the energizer or solenoid core 10 is shown.

この通過孔３２或いは４３は、島状でも、連続状孔でもよいが、インナー弁及び弁座の強度に悪影響を与えない形状がよい。そのような形状の１つには、同心円の溝、或いは孔である。図４は、その同心円に設けた通過孔３２を有するインナー弁の斜視図である。インナー弁は、高速で往復運動を行うために、通過孔をそこに設けても、強度を保持する必要がある。図４Ａに示すように、強度補強のために、同心円の孔３２に対して、リブ３１を設ける。
図４Ｂは、インナー弁を上から見た平面図である。
そして、図３の断面図に示すように、通過孔３２がある位置に相当する弁座４の領域４３には、通過孔４２を設けない。図３は、インナー弁３、１３及び弁座４、１４の両方に、通過孔３２と４２を設けた例を示す。
即ち、インナー弁３、１３は、適宜配置された流体通過孔３２を有し、それと向き合う弁座４、１４は、インナー弁の通過孔３２と向き合って配置された閉鎖領域４３を有する。換言すれば、閉鎖位置においては、インナー弁３、１３と弁座４、１４の間には、開放領域なく、即ち、流体通過がなく、流体の漏洩がない構成である。 The passage hole 32 or 43 may be an island shape or a continuous hole, but preferably has a shape that does not adversely affect the strength of the inner valve and the valve seat. One such shape is a concentric groove or hole. FIG. 4 is a perspective view of the inner valve having the passage holes 32 provided in the concentric circles. Since the inner valve reciprocates at a high speed, it is necessary to maintain strength even if a passage hole is provided there. As shown in FIG. 4A, ribs 31 are provided in concentric holes 32 for strength reinforcement.
FIG. 4B is a plan view of the inner valve as viewed from above.
And as shown in sectional drawing of FIG. 3, the passage hole 42 is not provided in the area | region 43 of the valve seat 4 corresponding to the position with the passage hole 32. As shown in FIG. FIG. 3 shows an example in which passage holes 32 and 42 are provided in both the inner valves 3 and 13 and the valve seats 4 and 14.
That is, the inner valves 3 and 13 have fluid passage holes 32 arranged as appropriate, and the valve seats 4 and 14 facing the inner passages 3 and 13 have closed regions 43 arranged facing the passage holes 32 of the inner valve. In other words, in the closed position, there is no open region between the inner valves 3 and 13 and the valve seats 4 and 14, that is, there is no fluid passage and no fluid leakage.

エンジンの回転運動に合わせた流体燃料を供給するために高速で開閉する弁装置において、弁部分として、上下の連結した一対の弁体を採用することにより、部品の数と構造が複雑になり、加工や組立てが困難になり、精度の調整、加工精度などが問題になる。それを、上下の弁体の間に、即ち、上部インナー弁３と下部インナー弁１３の間に、すきま調整材８、例えば、皿ばね８を採用することにより、加工誤差を、組立て時に調整可能にした。
そして、下部弁座１４が載る支持体１５との間にも、弾性材９を挟むことにより、０．１〜０．２ｍｍの上下弁体（３、４）（１３、１４）の間の寸法誤差を自動調整できる機構を挿入して、複雑で、精度よい組立ての問題を解決した。 In a valve device that opens and closes at high speed to supply fluid fuel that matches the rotational movement of the engine, adopting a pair of upper and lower connected valve bodies as the valve part makes the number and structure of parts complicated, Processing and assembly become difficult, and accuracy adjustment, processing accuracy, and the like become problems. By using a clearance adjustment material 8, for example, a disc spring 8, between the upper and lower valve bodies, that is, between the upper inner valve 3 and the lower inner valve 13, machining errors can be adjusted during assembly. I made it.
And the dimension between 0.1-0.2-mm upper-lower valve bodies (3, 4) (13, 14) by pinching the elastic material 9 also between the support bodies 15 in which the lower valve seat 14 is mounted. A mechanism capable of automatically adjusting the error was inserted to solve the complicated and accurate assembly problem.

産業上の利用可能性は、従来の単座弁での燃料の通過面積の不足を解決し、同時に供給圧力も低く限定される欠点を解消する。
従来の単座弁での供給圧力の一次側とエンジンに流れ込む二次側の圧力差が、弁の流体通過面積にそのまま加わる押し付け力にあるために、弁を開く方向への負担が大きくなり、流体の通過面積も限定される点を解決した。
即ち、流体の通過面積を大きくし、同時に供給圧力を上げることができるようにした。２つの弁体を採用し、一方の弁体には弁の開く方向にかかり、他方の弁体には弁の閉まる方向に掛かるために、圧力バランスをとることができ、高速開閉の駆動力を助け、より大きな供給圧力を使用することができる高速開閉弁装置を提供できた。また、供給能力が十分でなかったり、供給側の圧力変動が大きい場合でも、安定した供給が可能になる流体高速開閉弁装置が得られることである。
更に、本発明の流体高速開閉弁装置の採用により、エンジンに吹き込まれる燃料量を増大でき、同一排気量で高出力が可能になり、燃料供給量の調整範囲を広げることができ、エンジンの設計の自由度も広がり、クリーンで高性能なエンジンも可能になった。 Industrial applicability solves the shortage of fuel passage area with conventional single seat valves and at the same time eliminates the disadvantage of limited supply pressure.
Since the pressure difference between the primary side of the supply pressure of the conventional single seat valve and the secondary side flowing into the engine is the pressing force directly applied to the fluid passage area of the valve, the burden on the valve opening direction increases, Solved the problem that the passage area was limited.
That is, the passage area of the fluid is increased, and the supply pressure can be increased at the same time. Adopting two valve bodies, one valve body is applied in the valve opening direction, and the other valve body is applied in the valve closing direction. It was possible to provide a high speed on-off valve device that can help and use a larger supply pressure. Further, it is possible to obtain a fluid high-speed on-off valve device that enables stable supply even when the supply capacity is insufficient or the pressure fluctuation on the supply side is large.
Furthermore, by adopting the fluid high-speed on-off valve device of the present invention, the amount of fuel injected into the engine can be increased, high output can be achieved with the same displacement, the adjustment range of the fuel supply amount can be expanded, and the engine design The degree of freedom has also expanded, and a clean, high-performance engine has become possible.
