This invention relates to an air proportional control device.
（以下考案の目的）
燃料流量の変化による圧力変化を利用することによって

び各種弁の構成が繁雑となる欠点がある。(Purpose of the invention hereinafter) A device that changes the combustion air by utilizing pressure changes caused by changes in fuel flow rate is disclosed in, for example, Japanese Patent Application Laid-open No. 61725 of 1972. Since the flow rate control device and the air and fuel mixing sections are each configured separately, there is a disadvantage that piping is required and the orifices and various valves associated therewith are complicated.
本考案は、混合部と空気流量制御部を一体横取すること
によって全体の構成を簡易化して前記欠点を除去すると
共に巾の広い範囲にわたって燃焼量を制御することを目
的とするものであり、以下図について詳述すると次の通
りである。The purpose of the present invention is to simplify the overall configuration by integrating the mixing section and the air flow rate control section, thereby eliminating the above-mentioned drawbacks and controlling the combustion amount over a wide range. The details of the figure are as follows.
（以下考案の構成、作用）
符号１は混合室であって、この混合室１の一側に空気室
２を設け、該空気室２と前記混合室１とを連通孔３ａ、

導くように構成する。(Structure and operation of the invention hereinafter) Reference numeral 1 denotes a mixing chamber, and an air chamber 2 is provided on one side of the mixing chamber 1, and a communication hole 3a connects the air chamber 2 and the mixing chamber 1.
3b, the air chamber 2 is provided with a diaphragm 5 integrated with a valve body 4, and the valve body 4 is installed in one of the communication holes 3b, so that the valve body 4 freely communicates with the communication hole 3b. In addition, a fuel nozzle 6 is provided in the mixing chamber 1, and the back pressure of the nozzle 6 is introduced to one side 11 of the diaphragm 5.
しかして、いま燃料ノズル６から混合室１内に燃料が噴
出し、この噴出量が多い時、即ちノズル６の背圧が高い
時は、その圧力連絡管７を介して、ダイヤフラム５の一

体４を押し上げ、この弁体４の開口度によって、空気導
入口８から圧送されてきた空気室２内の空気の混合室１
内への流入量をコントロールする。Now, when fuel is ejected from the fuel nozzle 6 into the mixing chamber 1 and the amount of ejection is large, that is, when the back pressure of the nozzle 6 is high, the fuel is ejected from the fuel nozzle 6 into the mixing chamber 1 via the pressure communication pipe 7, In other words, the air is transmitted to one side 11 of the diaphragm 5 in the figure, pushes up the valve body 4, and due to the degree of opening of the valve body 4, the air in the air chamber 2 that has been pressure-fed from the air inlet 8 is mixed in the mixing chamber 1.
Control the amount of inflow into the interior.
この時空気室２内の空気は、連通孔３ａからも同時に混
合室１内に流入している。At this time, the air in the air chamber 2 is simultaneously flowing into the mixing chamber 1 through the communication hole 3a.
燃料ガスと空気は混合室１内で混合して混合ガス出口９
から燃焼部へと流出する。Fuel gas and air are mixed in the mixing chamber 1 and the mixed gas outlet 9
and flows out into the combustion section.
燃料ブスの噴出量が少ない時、例えば最少ガス量の時は
、燃料ノズル６の背圧が低く、この時は、弁体４の自重
とスプリング１０ａ、 １０ｂとによって弁体４は閉の
状態を維持し、空気は連通孔３ｂからは混合室１内に流
入せず、連通孔３ａのみから混合室１内に流入する。When the amount of fuel jetted out from the fuel bus is small, for example when the amount of gas is minimum, the back pressure of the fuel nozzle 6 is low, and at this time, the valve body 4 is kept in the closed state by its own weight and the springs 10a and 10b. The air does not flow into the mixing chamber 1 through the communication hole 3b, but flows into the mixing chamber 1 only through the communication hole 3a.
即ち本考案は、連通孔３ａ、３ｂを設け、燃料ノズルの
背圧が低い時は、燃料ノズルからの噴出量に見合った空
気量を連通孔３ａからのみ混合室１内へ流入させるよう
に制御すると共に燃料ノズルの背圧が高い時は連通孔３
ｂの開口度を制御して燃料の噴出量に見合った空気量を
混合室１内に流入させるようにしたものである。That is, the present invention provides communication holes 3a and 3b, and when the back pressure of the fuel nozzle is low, controls such that an amount of air commensurate with the amount of jetting from the fuel nozzle flows into the mixing chamber 1 only from the communication hole 3a. At the same time, when the back pressure of the fuel nozzle is high, the communication hole 3
By controlling the opening degree of b, an amount of air commensurate with the amount of fuel ejected is allowed to flow into the mixing chamber 1.
