この考案は、ピストン型のスロットル弁を有する気化器
の防振装置に関する。[Detailed Description of the Invention] This invention relates to a vibration isolating device for a carburetor having a piston-type throttle valve.
気化器には、横方向に設けた通気路 ピストン型のスロ
ットル弁が交叉し、スロットル弁はバネによって押えら
れて通気路を閉じ、操作ワイヤでバネに抗してスロット
ル弁を引上げて通気路を開くものがある。In the carburetor, a piston-shaped throttle valve intersects with the ventilation passage installed in the horizontal direction.The throttle valve is pressed down by a spring to close the ventilation passage, and the throttle valve is pulled up against the spring using an operating wire to open the ventilation passage. There's something to open.
このピストン型のスロットル弁は、吸入空気の脈流動と
バネが共振して、上下に振動することが起って不都合で
、スロットル弁が異状摩耗したり、空燃 等のセツティ
ングに異状を生じる。This piston-type throttle valve is inconvenient because the spring resonates with the pulsating flow of intake air, causing it to vibrate up and down, causing abnormal wear on the throttle valve and abnormal air/fuel settings. .
この考案は、かかる点に鑑み、スロットル弁が振動しな
いように改善したもので、以下図面に示す本考案の実施
例について説明する。In view of this point, this invention has been improved so that the throttle valve does not vibrate, and an embodiment of the invention shown in the drawings will be described below.
気化器１は、横方向に通気路２が設けられ、この通気路
２を上下に摺動自在に設けたピストン型のスロットル弁
３が遮ぎる。The carburetor 1 is provided with a ventilation passage 2 in the lateral direction, and this ventilation passage 2 is blocked by a piston-type throttle valve 3 provided vertically slidably.
スロットル弁３は、バネ４で下側に弾圧されており、操
作ワイヤ５をバネ４に抗して引上げることによって開閉
操作をする。The throttle valve 3 is pressed downward by a spring 4, and is opened and closed by pulling up an operating wire 5 against the spring 4.
通気路２の下側には、フロートによって燃料を一定レベ
ルに保つフロート室６がある。Below the air passage 2 there is a float chamber 6 in which the fuel is kept at a constant level by means of a float.
そして、燃料はメインジェットＩを通って、通気路２に
吸出される。Then, the fuel passes through the main jet I and is sucked out into the air passage 2.
而して本考案は、スロットル弁３の下端−側に、プラン
ジャ軸８を固定し、プランジャ軸８をフロート室６内に
貫通させて挿入し、下端にプランジャ９を固定する。Accordingly, in the present invention, a plunger shaft 8 is fixed to the lower end side of the throttle valve 3, the plunger shaft 8 is inserted through the float chamber 6, and a plunger 9 is fixed to the lower end.
一方、フロート室６０下底にシリンダ１０を立設し、シ
リンダ１０内にプランジャ９を挿入する。On the other hand, a cylinder 10 is installed upright at the bottom of the float chamber 60, and a plunger 9 is inserted into the cylinder 10.
プランジャ９には小孔１１を設け、シリンダ１０の下部
の窓孔１２に、小孔１３を設けた外開き一方弁１４を設
ける。The plunger 9 is provided with a small hole 11, and the lower window hole 12 of the cylinder 10 is provided with an outwardly opening one-way valve 14 with a small hole 13 provided therein.
作用について説明する。The effect will be explained.
シリンダ１０内には、常に燃料が流れ込んでいる。Fuel is constantly flowing into the cylinder 10.
操作ワイヤ５を引くと、小孔１１及び小孔１３のみを燃
料が流れ、燃料が作動流体となってその圧縮性により、
スロットル弁３の上下振動を緩和する。When the operating wire 5 is pulled, fuel flows only through the small holes 11 and 13, and the fuel becomes a working fluid, and due to its compressibility,
To alleviate vertical vibration of the throttle valve 3.
又、スロットル弁３が下方に下るときは、外開き一方弁
１４が開いて速やかに下る。Further, when the throttle valve 3 moves downward, the outward opening one-way valve 14 opens and the throttle valve 3 moves downward quickly.
こうして、スロットル弁３の上下振動を、燃料を作動流
体として緩和させる。In this way, the vertical vibration of the throttle valve 3 is alleviated using the fuel as the working fluid.
以上説明したように、この考案は、気化器の通気路に交

有する。As explained above, this invention is equipped with a piston-type throttle valve that intersects with the air passage of the carburetor.
A granger shaft is passed through the float chamber on the lower end side of the throttle valve, a plunger is provided at the lower end, a cylinder is provided in the float chamber and the plunger is inserted, a small hole is provided in the granger, and a small hole is provided at the bottom of the cylinder. Since a one-way valve that opens outward is provided, the vertical vibration of the throttle valve can be alleviated by using the fuel in the cylinder as the working fluid, and the setting is stable. The valve closes quickly, which is convenient and allows fuel to be used as a working fluid.
