Claims

[Scope of utility model registration request]

a primary throttle valve disposed in the primary passage; a bench lily disposed downstream of the primary throttle valve; and a nozzle portion formed by forming the outlet side of the bench lily into a cylindrical shape; a fuel supply mechanism that supplies fuel near or upstream of the bench lily; and a fuel supply mechanism that supplies fuel near or upstream of the bench lily;
In an internal combustion engine air-fuel mixture supply device comprising a secondary passage that merges with the secondary passage and a secondary throttle valve disposed in the secondary passage, An air outlet is formed in a substantially annular shape, and the air intake, which is at approximately atmospheric pressure, communicates with the air outlet through an air introduction passage, and a predetermined air outlet is connected to the air introduction passage in conjunction with the throttle valve. A mixture supply device for an internal combustion engine, characterized in that it is provided with an air control valve that opens when the load exceeds the load.
