摘要： A carburetor (1) having a single fuel supply system of a simple construction and capable of stable fuel supply to an engine in an appropriate air-fuel ratio is provided. Air and fuel is mixed to obtain a constant air-fuel ratio in a negative pressure moderating chamber (13) so controlled under negative pressure that adverse effect of air compressibility can be practically negligible. Then, air-fuel mixture and main intake air metered through a main intake air restriction (8) are mixed at the restriction or in a main intake passage (3) downstream thereof. Both the air-fuel mixture and the main intake air are compressible fluids, so that there is a direct proportion between the intake air flow rate and the air-fuel mixture amount injected from the negative pressure moderating chamber (13). Thus, the air-fuel ratio of the mixture composed in said main intake passage (3) is kept constant in all the running operations of the engine. This permits fuel supply with a single supply system.
