イドル制御装置に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides idle control using a proportional control type electromagnetic actuator that automatically controls the idle rotation speed of an automobile to a set rotation speed based on water temperature or outside air temperature. Regarding equipment.
特開昭56−116967号公報で知られる従来のアイ

バイパス空気通路に２個の計量バルブを備えてい

The conventional idle control device known from Japanese Unexamined Patent Publication No. 56-116967 is as shown in FIGS. 1 and 3.
Two metering valves are provided in the bypass air passage.
このように構成された従来の装置では、それぞ
れの計量バルブを確実にシートに対して密接する
様に組み立てることが難しい。 In conventional devices configured in this manner, it is difficult to assemble each metering valve in such a way that it is reliably brought into close contact with the seat.
各計量バルブの加工公差、ボデイに形成された
シート部の加工公差、それらの組付け公差等が累
積して通常600ミクロン程度の公差を見込む必要
がある。 Normally, it is necessary to allow for a tolerance of about 600 microns, which is a cumulative total of the processing tolerances of each metering valve, the processing tolerances of the seat formed on the body, and their assembly tolerances.
このため最終的にどちらかの計量バルブがシー
トから上記公差の分だけ離間した状態で組付けら
れる可能性がある。 Therefore, there is a possibility that one of the metering valves is finally assembled with a distance corresponding to the above-mentioned tolerance from the seat.
通常この２計量バルブタイプのアイドル制御装
置では、両計量バルブが密接状態で組付けられた
とき、両計量バルブに作用する負圧の影響が相殺
されるように設計されている。 Normally, this two metering valve type idle control device is designed so that when both metering valves are assembled in close contact, the effects of negative pressure acting on both metering valves are canceled out.
すなわち、一方の計量バルブには開度が増加す
る方向へ負圧が作用し、もう一方の計量バルブに
は開度が減少する方向へ負圧が作用するように構
成されており、しかも計量バルブの直径を異なら
しめてそれぞれの作用力が釣り合うように設計さ
れ、その結果電気信号入力に比例した計量バルブ
ストロークが得られるように構成されている。 In other words, one metering valve is configured so that negative pressure acts in the direction of increasing the opening, and the other metering valve is configured so that negative pressure acts in the direction of decreasing the opening. The valves are designed to have different diameters so that their acting forces are balanced, resulting in a metered valve stroke proportional to the electrical signal input.
従つて上記のように一方の計量バルブが離間状

スがくずれ、計量バルブを開く側の作用力か、閉
じる側の作用力かいずれかが残つて、その結果電
気信号入力に比例した計量バルブストロークが得
られなくなる。 Therefore, in a device where one metering valve is assembled with one metering valve separated from the other as described above, the effect of negative pressure will be unbalanced, and either the acting force on the opening side of the metering valve or the acting force on the closing side will remain. As a result, a metered valve stroke proportional to the electrical signal input cannot be obtained.
さらに困つたことに、どちらの計量バルブがシ
ートに対して離間状態になるか予測が付かないの
である。このため離間時のうまい補正策がないと
いう問題が残る。 To make matters worse, it is impossible to predict which metering valve will be separated from the seat. For this reason, the problem remains that there is no effective corrective measure when separating.

２計量バルブを通つて流れる空気流量が略一定に
なる様にするものであるが、このそうちにおいて
も、第１、第２軽量バルブの微小開度領域では、
従来と同様、差圧の影響を受ける。 The idle control device disclosed in Japanese Utility Model Application Publication No. 57-83251 is designed to keep the air flow rate through the second metering valve approximately constant in a region where the intake pipe negative pressure is 300 mmHg or more. Even in this case, in the minute opening range of the first and second lightweight valves,
As before, it is affected by differential pressure.
なぜならオリフイス９の面積より第２計量バル
ブの開度が十分大きくならないと、オリフイス９
の絞り効果が得られないからである。 This is because if the opening degree of the second metering valve is not sufficiently larger than the area of the orifice 9, the orifice 9
This is because the aperture effect cannot be obtained.

An object of the present invention is to maintain the flow rate characteristic of an idle control device at a predetermined flow rate characteristic set in advance with respect to an electrical input signal even if the intake pipe negative pressure fluctuates.

This metering valve generates an acting force opposite to the acting force, and is provided with a differential pressure compensating valve that is loosely fitted into a sleeve disposed in the bypass passage.

This is a crank angle sensor that detects the rotation speed of the engine and converts it into electrical output.
１４は各種の入力信号を受け、これを演算処理
して、比例制御装置１５や燃料噴射弁１６に所定
の出力を供給する演算処理回路（コンピユータ）
で、エンジンの電子制御の中枢部をつかさどるも
のである。 14 is an arithmetic processing circuit (computer) that receives various input signals, processes them, and supplies predetermined outputs to the proportional control device 15 and the fuel injection valve 16.
It controls the central part of the engine's electronic control.
比例制御装置１５はスロツトルチヤンバー６の
バイパス通路５に設置され、絞弁４をバイパスす
るバイパス空気量を制御する。 The proportional control device 15 is installed in the bypass passage 5 of the throttle chamber 6 and controls the amount of bypass air that bypasses the throttle valve 4.
ここで比例制御装置は、円筒形のコイル１７の
中心部に配置されるとともに、互いの対向部断面
が円錐形に形成されたコア１８とプランジヤ１９

２１を有するボデイ２２、その途中に形成した一
対のシート２３，２４、一対の計量弁２５，２６
を備えた流量制御機構部２７とから構成される。 Here, the proportional control device is disposed at the center of a cylindrical coil 17, and includes a core 18 and a plunger 19, each of which has a conical cross section at opposing parts.
an electromagnetic mechanism section 20, a body 22 having an air passage 21 to be controlled, a pair of seats 23, 24 formed in the middle thereof, and a pair of metering valves 25, 26.

It has the function of converting.
そして、これによつて自動車のアイドル運転時
のエンジン回転数が、予め設定された所望のエン
ジン回転数となるよう、バイパス空気量を加減す
る。 Thereby, the amount of bypass air is adjusted so that the engine speed during idling of the automobile becomes a preset desired engine speed.
すなわち、水温とエンジン回転数を検知して、
このエンジン回転数を予め定められた所定値に自
動的に且つ連続的に制御する機能を有するもので
ある。 In other words, by detecting water temperature and engine speed,
It has a function of automatically and continuously controlling the engine speed to a predetermined value.
このように本装置は従来のオンオフソレノイド
と異なり、連続動作であるため、第２図に示す如
く、入出力特性が、計量バルブの両端に加わる差
圧の影響を受けるという欠陥を有している。 Unlike conventional on/off solenoids, this device operates continuously, so it has the drawback that the input/output characteristics are affected by the differential pressure applied to both ends of the metering valve, as shown in Figure 2. .
この原因は、従来装置の計量部が第３図に示す
如く、一対のシート２３，２４と一対の計量弁２
５，２６とで構成されているためである。 The reason for this is that the measuring section of the conventional device has a pair of seats 23, 24 and a pair of metering valves 2, as shown in FIG.
This is because it is composed of 5 and 26.
すなわち計量バルブとシートの加工公差のため
シート間の寸法２７と計量バルブ間の寸法２８と
が完全には一致せず、さらにそれらの組立て公差
などが累積して、最終組立て状態でどちらか一方
のシート部が密接しない状態となる。 In other words, due to processing tolerances between the metering valve and the seat, the dimension 27 between the seats and the dimension 28 between the metering valves do not completely match, and furthermore, these assembly tolerances accumulate, and in the final assembled state, either one The seat portions are not in close contact with each other.
その結果、互いの計量バルブに作用する負圧の
作用力F1，F2が設計時の作用力と異なる値にな
り、両計量バルブに作用する負圧による作用力の
バランスがくずれ、計量弁には電磁力以外の有害
な負圧力が加わつて計量誤差が生ずることにな
る。 As a result, the forces F 1 and F 2 of the negative pressure acting on each metering valve become values different from the forces at the time of design, and the balance of the forces caused by the negative pressure acting on both metering valves is lost, causing the metering valve to Harmful negative pressure other than electromagnetic force is applied to the device, resulting in measurement errors.
この点については、上記従来例の項で詳述した
とおりである。 This point is as described in detail in the section on the conventional example above.
本発明は以上の点に鑑みてなされたもので、以
下図面に示す実施例により本発明を詳細に説明す
る。 The present invention has been made in view of the above points, and will be described in detail below with reference to embodiments shown in the drawings.
尚第１図、第３図と同一符号の物は同一物もし
くは均等物を示すものとする。 Components with the same reference numerals as in FIGS. 1 and 3 indicate the same or equivalent components.
第４図は本発明の一実施例を示す断面図で、計
量部は１ケのシート２３と１ケの計量バルブ２５
とで構成される。 FIG. 4 is a cross-sectional view showing one embodiment of the present invention, in which the metering section includes one seat 23 and one metering valve 25.
It consists of
２９はスリーブ、３０は補償弁で、これらスリ
ーブ２９と補償弁３０とで負圧補償機構３１を構
成し、これらは前記計量バルブ２５と協動する。 29 is a sleeve, and 30 is a compensation valve. These sleeve 29 and compensation valve 30 constitute a negative pressure compensation mechanism 31, which cooperates with the metering valve 25.
負圧補償機構３１はスリーブ２９と補償弁３０
で形成されるクリヤランス３２を有し、該クリヤ
ランス３２は圧力を導くだけの機能を有し、空気
は実質的に流れない構造となつている。 The negative pressure compensation mechanism 31 includes a sleeve 29 and a compensation valve 30.
The clearance lance 32 has a function of only guiding pressure, and has a structure in which air does not substantially flow therethrough.
この機能を実現するために本実施例ではクリア
ランス３２を60乃至90μｍとし、更にバルブ２５
のフルストローク時でも、スリーブと圧力補償バ
ルブの対向面の軸方向長さを約３mm確保できるよ
うに構成している。 In order to realize this function, in this embodiment, the clearance 32 is set to 60 to 90 μm, and the valve 25 is set to 60 to 90 μm.
The structure is such that the axial length of the opposing surfaces of the sleeve and pressure compensation valve is approximately 3 mm even during full stroke.
この周方向のクリアランス３２の公差は、スリ
ーブの内径と補償弁３０の外径との加工公差だけ
で決まるので、従来の２バルブタイプの装置にお
けるバルブとシートとの間に生じる空〓の集積公
差より十分小さく設定でき、その結果、クリアラ
ンス自体を従来の空〓より上記の通り十分小さく
（約1/10）できるのである。 The tolerance of this circumferential clearance 32 is determined only by the machining tolerance between the inner diameter of the sleeve and the outer diameter of the compensation valve 30, so the tolerance for the accumulation of air between the valve and the seat in the conventional two-valve type device As a result, the clearance itself can be made sufficiently smaller (approximately 1/10) than the conventional clearance as described above.
本実施例は以上の通り構成されるもので、今計
量バルブ２５の後流に負圧P1が印加されたとす
ると、該計量バルブ２５に加わる静圧力は
F1＝負圧P1×計量バルブ２５の面積S1
となる。 The present embodiment is configured as described above, and if negative pressure P 1 is now applied to the downstream side of the metering valve 25, the static pressure applied to the metering valve 25 is F 1 = negative pressure P 1 × metering valve 25 area S 1 .
一方このとき補償弁３０にも同一の負圧P1が
加わるので、その静圧力は
F2＝負圧P1×補償弁30の面積S2
となり、F1＝F2となるようにすると、負圧の大
きさが変動しても、計量バルブ２５のストローク
は影響を受けないことになる。 On the other hand, at this time, the same negative pressure P 1 is also applied to the compensation valve 30, so its static pressure is F 2 = negative pressure P 1 × area S 2 of the compensation valve 30, so that F 1 = F 2 . Even if the magnitude of the negative pressure changes, the stroke of the metering valve 25 will not be affected.
換言すると、計量バルブ２５で計量された空気
流量は、負圧の影響を受けないこととなる。 In other words, the air flow metered by the metering valve 25 is not affected by negative pressure.
クリヤランス３２は負圧のみを導き、空気を流
さないことが必要である。 It is necessary that the clearance 32 conducts only negative pressure and does not allow air to flow.
そのため、第５図に示す如く、ラビリンス構造
３３にすれば、ここで渦流が発生し、流れエネル
ギーが消滅するので、シール効果は更に向上す
る。 Therefore, if a labyrinth structure 33 is used as shown in FIG. 5, a vortex is generated here and the flow energy disappears, so that the sealing effect is further improved.
また、第６図に示す如く、スリーブ２９の先端
部にリング部２９ａを設け、このリング部２９ａ
と補償弁３０とを密接させ、ここからの空気洩れ
を減少させることもできる。 Further, as shown in FIG. 6, a ring portion 29a is provided at the tip of the sleeve 29, and this ring portion 29a
It is also possible to bring the compensating valve 30 into close contact with each other to reduce air leakage therefrom.
さらに、第７図に示すごとく、スリーブの先端
部にゴムのような弾性体のリング２９ｂを取り付
けても良い。 Furthermore, as shown in FIG. 7, a ring 29b made of an elastic material such as rubber may be attached to the tip of the sleeve.
なお、このとき弾性リング２９ｂの収縮公差を
マイナスにしておけば計量バルブとシートとを当
接させた状態で確実に補償弁３０と弾性リング２
９ｂとを密接させることができ、クリアランスか
らの空気洩れを確実に防止できる。 At this time, if the contraction tolerance of the elastic ring 29b is set to a negative value, the compensating valve 30 and the elastic ring 2 can be reliably connected with the metering valve and the seat in contact with each other.
9b, and air leakage from the clearance can be reliably prevented.
以上のように構成した本発明によれば、入力電
気量に応じた正確な空気流量が得られ、負圧の影
響をなくすことができた。
According to the present invention configured as described above, an accurate air flow rate can be obtained according to the amount of input electricity, and the influence of negative pressure can be eliminated.
更に、計量バルブが一個ですむので、流量セツ
テイングが簡単となる。 Furthermore, since only one metering valve is required, flow rate setting becomes easy.
