摘要： A carburetor for internal combustion engines comprises, inter alia, a body tube into which the main feed circuit and the idling and progression feed circuit open.During cold-engine starting and operation, the richness and flow rate of the mixture delivered by the carburetor has to be increased. For this purpose, choke valves disposed in the carburetor body tube upstream of the main feed circuit have been used for some time, these when closed enabling the fuel to flow from this latter feed circuit even for low air throughputs through the tube. The carburetor throttle valve is also disposed in a "fast idle" position in order to increase the mixture flow rate.The invention generally relates to a device which controls the positions of the choke valve and throttle valve by taking account of the engine temperature, and more particularly which makes said positions entirely automatic, independently of correct use by the driver.
