Abstract
Improvements in carburettors for internal combustion engines, of the type that comprise in their intake duct, upstream of a main throttle member actuated by the driver, an auxiliary throttle member that opens automatically and progressively as it increases the flow of air that passes through said conduit and that controls a dosing organ that regulates the fuel flow directed towards said conduit from a fuel source, under the effect of the depression that reigns in a limited chamber in the aspiration conduit by said throttle members, so that the passage section offered to the air by said auxiliary throttle member and the passage section offered to the fuel by said dosing member are substantially proportional and that the air and fuel thus supplied form, in normal operation, a mixture of sensibly constant wealth, comprising the dosing member a tubular piece one of whose ends communicates with a point of the intake duct where the pressure prevails between said throttle members and of which an opening faces a cylindrical body dragged in rotation by the auxiliary throttle member and whose wall presents a port in communication with the fuel source, communicating a fraction of the port, variable with the angular position of said body, with a channel delimited by the tubular part, characterized in that a portion of the tubular part provided with Said opening is held elastically in contact with the cylindrical body.
