Claims

[Scope of utility model registration request]

An air chamber communicating with the air bleed chamber is provided, this air chamber is partitioned by a diaphragm to form a negative pressure chamber at the back thereof, and this negative pressure chamber is communicated with the intake passage downstream of the throttle valve through a negative pressure passage. A carburetor characterized in that a spring is disposed in the negative pressure chamber, which is compressed by the negative pressure of the intake air of the engine, expands by the negative pressure when the throttle valve is suddenly opened, and forces the air in the air chamber into the air bleed chamber. Accelerator.
