Abstract
A carburetor air control valve device which accurately meters air flow to each of the ports of a carburetor. A plurality of closure members of the poppet type are operated by expansion of a bellows member, as the bellows member expands in response to changes in density of the air to which the valve device is subjected. Each of the closure members is adapted to control flow of air to a port of an automotive carburetor.
