In more detail, the mist of fuel injected from the fuel injection valve of the fuel injection device/163 Improvements have been made to reflectors for the injected fuel, but these are not sufficient, and the mist of fuel injected from the fuel injection valve of the fuel injection device is not sufficient. 1) The present invention provides an injection port of such a fuel injection valve in a part of the fuel injection valve, injects fuel into the part where the flow velocity is high, and sufficiently atomizes the fuel to create the optimum air-fuel mixture for the internal combustion engine. A fuel injection valve mixing device (i.e., a device that works to mix and atomize the fuel injected from the fuel injection valve and the intake air), which is equipped with a throttle valve and a variable valve in addition to the fuel injection valve. The present invention relates to a variable venturi fuel injection valve mixing device.

The inside of the cover is divided into a partial pressure receiving chamber 10 and a lower atmospheric chamber 11 by the diaphragm 9, and the pressure receiving chamber 10 is connected to an intake passage from a negative pressure introduction hole 12 formed at the bottom of the slide valve 6. The negative pressure inside the chamber 2 is introduced, and the atmosphere is introduced into the atmospheric chamber 11 through the atmosphere introduction hole 13. Also, 14 is the intake path 2
It is connected to an accelerator pedal, accelerator lever, etc. (not shown) by a throttle valve placed inside.

性能に欠点が見られた。Arrow A indicates the flow direction of the intake air, and in FIG. 1 the sliding valve 6 is in the lowest position. The negative pressure in the intake passage 2 generated by the operation of the internal combustion engine is transferred from the negative pressure introduction hole 12 to the pressure receiving chamber 1.
Since the atmospheric air is introduced into the atmospheric chamber 11 through the atmospheric air introduction hole 13, the sliding valve 6 moves upward or downward depending on the force relationship between the negative pressure, atmospheric pressure, and the spring 7. However, since the atmospheric pressure and the force of the spring 7 vary slightly, the slide valve 6 is operated mainly by negative pressure. In such a conventional variable venturi fuel injection valve mixing device, no matter how the size of the intake passage of the variable venturi part 3 in which the sliding valve 6 is in the lowest position is set, there is a drawback in performance during idle link or low speed operation. It was observed.

適の混合気が得られず、又。In other words, when the sliding valve 6 is at the lowest position,
If the intake passage is set relatively large, the throttle valve 14 will be used for the section where the flow velocity is high during drinking or low speed operation.
, and even if the fuel is injected from the injection port 5 into the variable venturi part 3, the atomization will be insufficient and the optimum air-fuel mixture will not be obtained.

動弁６が不要な動揺を起し。If the intake passage of the variable valve pilot part 3 in the lowest position of the sliding valve 6 is set to be relatively small, the sliding valve 6 will receive unstable or subtle negative pressure fluctuations of the internal combustion engine during idle link or low speed operation. causes unnecessary agitation.
これは摺動弁６が主として負圧により作動するため避け
ることが出来ず、従って吸気流速が安定せず霧化が不適
当で最適な混合気が得られなかった。This cannot be avoided because the sliding valve 6 is operated mainly by negative pressure, and therefore the intake air flow rate is not stable, atomization is inadequate, and an optimal air-fuel mixture cannot be obtained.

弁混合装置を提供することを目的とする。The present invention has been proposed in order to improve the above-mentioned drawbacks, and by providing independent fuel injection ports near the throttle part and near a part of the variable venturi, the present invention has been proposed to improve the idling of the internal combustion engine or from low-speed to high-speed operation. It is an object of the present invention to provide a variable venturi fuel injection valve mixing device capable of supplying a sufficiently atomized air-fuel mixture over the entire operating range.
以下、第１の発明の一実施例を第２図により説／１６６ 明を省略する。An embodiment of the first invention will be explained below with reference to FIG. Omit the description.

不安定な負圧を受けて動揺しないように構成する。4A is a fuel injection valve provided near the throttle valve 14 and is provided independently from the fuel injection valve 4 provided near the variable injection valve part 3, and 5A is an injection port of the fuel injection valve 4A that connects the throttle valve 14.
The intake passage of the variable venturi part 3 with the sliding valve 6 at the lowest position is provided independently from the injection port 5 of the fuel injection valve 4 which opens near the variable venturi part 3. It is set relatively large so that the sliding valve 6 mainly operates only during medium or high speed operation, and does not oscillate due to unstable negative pressure of the internal combustion engine during idle link or low speed operation.

内燃機関に最適の混合気を供給出来るものである。According to the above structure, during idle link or low speed operation, the flow velocity near the throttle valve 14 is the fastest, so the fuel injection valve 4A is driven and fuel is injected from the injection port 5A to achieve sufficient atomization, which is optimal for internal combustion engines. In addition to being able to supply the air-fuel mixture, the flow velocity near the injection port 5A is determined by the throttle valve 14, so even if the engine receives unstable negative pressure during idling or low speed, the intake flow velocity remains /I67.Ideal for internal combustion engines. It is capable of supplying air-fuel mixture.

に行ない内燃機関に対して最適の混合気を供給出来る。In addition, during medium and high speed operation, the fuel injection valve 4 is driven to inject fuel from the injection port 5 provided near the variable venturi part 3, so that the optimum venturi opening degree can be adjusted according to the negative pressure of the internal combustion engine. Since the setting is made by the sliding valve 6, the fuel can be sufficiently atomized by the variable fuel valve part 3, which has the fastest flow rate, and the optimum air-fuel mixture can be supplied to the internal combustion engine.
