Abstract

Improvements in the carburation devices, for internal combustion engines that present in their intake duct, upstream of the main throttle member actuated by the driver, an auxiliary throttle member that opens automatically and progressively as the flow rate increases. air that passes through said conduit and that sends a dosing organ that regulates the fuel flow from a fuel source at a pressure substantially equal to atmospheric pressure and that is admitted to said conduit under the effect of the depression that reigns between the two organs throttle, in such a way that the section of the air passage, determined by said auxiliary throttle member, and the section of the fuel passage determined by said dosing member, are substantially proportional and that the air and fuel thus supplied, under the same pressure difference, form, in normal operation, a appreciably constant mixture of richness, which carburation device also consists of a starting system that comprises a first fuel circuit that empties into the intake duct between its two throttle members and on which a controlled distributor is mounted, on the one hand, by a temperature-sensitive elastic organ that tends to open the distributor when the temperature drops and, on the other hand, by a pneumatic, pressure-sensitive organ that prevails in the intake duct downstream of the main throttle member, which tends to partially close the distributor when this last pressure falls below a certain value, characterized in that the starting system comprises a second fuel circuit controlled solely (that is, excluding the temperature-sensitive organ) by said organ tire so that it opens when the engine is stopped or dragged by the demarr é and closes it when the motor turns by itself, said second circuit also being arranged so as not to open more than if the first circuit is also open.
