Air Valve Carburetor
« Back to Glossary Index
Air-Valve Carburetor:
A type of carburetor where a spring-closed or weight-closed air valve opens in response to engine demand. The opening of this valve, through suitable linkage, adjusts the fuel-orifice opening to ensure the desired air-fuel mixture ratio throughout the range of engine operation.
Principles: Operates on principles such as constant vacuum, constant depression, or variable Venturi.
Examples: SU (Skinner Union) and Stromberg CD (Constant Depression) carburetors.
