Full Title

Carburettors with means for influencing, e.g. enriching or keeping constant, fuel/air ratio of charge under varying conditions (choke valves for starting F02M1/00) > Other installations, with moving parts, for influencing fuel/air ratio, e.g. having valves (F02M7/24 takes precedence) > fuel flow cross-sectional area being controlled dependent on air-throttle-valve position (the throttle valve being slidably arranged transversely to air passage F02M9/06)
