, 12, 13, a starting shaft 4 is slidably mounted horizontally in communication with the outside of each carburetor 1, 2.3.
14,15.16は各気化器に設けられた上記始動軸4
の軸承である。14, 15, and 16 are the starting shafts 4 provided in each carburetor.
This is the bearing.
該始動軸4には夫夫の気化器の始動装置11,12,1
3の始動プランジャー作動ロッド17,18,19の作
動レバー20.21.22を固定する。The starting shaft 4 is equipped with starting devices 11, 12, 1 for the husband's carburetor.
The actuating levers 20, 21, 22 of the starting plunger actuating rods 17, 18, 19 of No. 3 are fixed.
そして中央の気化器2の上部(或いは気化器にブラケッ
トを装着し或いは気化器以外の気化器附近のエンジン部
等)に始動弁自動調整装置5が取付けられる。An automatic starting valve adjustment device 5 is attached to the upper part of the central carburetor 2 (or to a bracket attached to the carburetor, or to an engine part other than the carburetor near the carburetor).
該始動弁自動調整装置5は吸入管(図示しない)と負圧
管51で接続し、作動ダイヤフラム52及び53を備え
る負圧室54を設ける。The automatic starting valve adjustment device 5 is connected to a suction pipe (not shown) through a negative pressure pipe 51, and is provided with a negative pressure chamber 54 having operating diaphragms 52 and 53.
該ダイヤフラム52,53はその中間即ち負圧室54内
に設けられるコイルばね55で通常は張圧されている。The diaphragms 52 and 53 are normally tensioned by a coil spring 55 provided between them, that is, within the negative pressure chamber 54.
上記ダイヤフラム53には椀状のセットプレート56が
取付けられる。A bowl-shaped set plate 56 is attached to the diaphragm 53.
又ダイヤフラム52はその外部(負圧室54外部)K負
圧作動ロッド57を取付ける。Further, a negative pressure operating rod 57 is attached to the outside of the diaphragm 52 (outside the negative pressure chamber 54).
更に上記ダイヤフラム53の負圧室54反対側に、機関
温度を感知して温度上昇時に開き、低下時に閉じる感温
弁6を介して負圧管61により吸入管と通ずる感温負圧
室58を備え、通常はばね59で負圧室54側に押圧さ
れているが、ダイヤフラム53に固定される抑止ロッド
60によりダイヤフラム53は一定位置に保持される。Further, on the opposite side of the negative pressure chamber 54 of the diaphragm 53, there is provided a temperature-sensitive negative pressure chamber 58 that senses the engine temperature and communicates with the suction pipe through a negative pressure pipe 61 via a temperature-sensitive valve 6 that opens when the temperature rises and closes when the temperature falls. Although the diaphragm 53 is normally pressed toward the negative pressure chamber 54 by a spring 59, the diaphragm 53 is held in a fixed position by a restraining rod 60 fixed to the diaphragm 53.
そして気化器12との頭部に取付けられたブラケツット
11に設けられたビン72に連結レバー7を枢支し、そ
の上部尖端は上記負圧作動ロッド57の尖端を回動自在
に支承し、下部尖端は上記始動軸4と自由に係合する。The connecting lever 7 is pivotally supported on a pin 72 provided on a bracket 11 attached to the head of the carburetor 12, the upper tip of which rotatably supports the tip of the negative pressure operating rod 57, and the lower The tip engages freely with the starting shaft 4.
以上のように構成されるので、機関始動時は始動弁自動
調整装置5の負圧作動ロッド57は、ばね55に押圧さ
れて外方(図の左方)に一杯に突出されて、従って始動
軸4を右方に寄せ、始動用プランジャーの作動ロッド1
7,18,19は作動レバー20,21,22により一
杯に開けられている(図示の位置)。With the structure described above, when the engine is started, the negative pressure actuating rod 57 of the automatic starting valve adjustment device 5 is pushed by the spring 55 and fully protrudes outward (to the left in the figure), so that the engine starts. Move the shaft 4 to the right and move the starting plunger operating rod 1.
7, 18, 19 are fully opened by operating levers 20, 21, 22 (positions shown).
従ってこの状態で始動すれば、機関に始動用濃混合気を
供給し、機関が起動すれば吸入管に負圧が働くので、始
動弁自動調整装置5の負圧室54には負圧が作用し、ダ
イヤフラム52がダイヤフラム53側に引寄せられて負
圧作動ロッド57が右方に摺動し始動軸4を左方に摺動
する。Therefore, if the engine is started in this state, a rich mixture for starting will be supplied to the engine, and when the engine starts, negative pressure will act on the suction pipe, so negative pressure will act on the negative pressure chamber 54 of the automatic starting valve adjustment device 5. Then, the diaphragm 52 is drawn toward the diaphragm 53, and the negative pressure operating rod 57 slides to the right, causing the starting shaft 4 to slide to the left.
従って作動レバー20 、21.22は始動プランジャ
ー作動ロッド17,18.19を左方に押圧して始動プ
シンジャーを若干閉じ、供給混合気を薄める。The actuating lever 20, 21.22 therefore pushes the starting plunger actuating rod 17, 18, 19 to the left, slightly closing the starting plunger and diluting the feed mixture.
機関の回転が安定して回転数が上昇して来れば吸入管負
圧(絶対値)が上昇し更に混合気を薄めるようになる。When the engine rotation becomes stable and the rotation speed increases, the suction pipe negative pressure (absolute value) increases, further diluting the air-fuel mixture.
然しダイヤフラム53にはセットプレート56が設けら

6の尖端に当接された位置に保持される。However, since the diaphragm 53 is provided with a set plate 56, the diaphragm 52 is attached to the set plate 56.
It is held in a position where it is in contact with the tip of No. 6.
即ち始動後の供給混合気は一定濃度に保持される。That is, the supplied air-fuel mixture is maintained at a constant concentration after startup.

。Then, when the engine temperature rises and exceeds a certain temperature,
The temperature-sensitive valve 6 opens and the suction pipe negative pressure comes to act on the temperature-sensitive negative pressure chamber 58 of the automatic starting valve adjustment device 5, and the diaphragm 53
(actuates to the right), thus actuating the diaphragm 52 to the right and starting plunger actuating rods 17, 18, 1.
9 to the left to dilute the supplied mixture, and the starter pusher is fully closed to make the supplied mixture a normal mixture.
