摘要
The downdraught variable venturi carburettor has an annular fuel orifice surrounding its mixing chamber, fuel being supplied to the orifice at angularly spaced locations in response to engine operation. A movable venturi is located centrally within the carburettor body, a second venturi defining the orifice being located radially adjacent the first. The venturis define an annular restricted air passage adjacent the fuel dispensing orifice. A throttling device axially moves the first venturi relative to the second this varying the size of the restricted air passage.
