  • Patent number: 4251472
    Abstract: A carburetor for combustion engines with a mixing chamber in the carburetor housing, the mixing chamber being bounded downstream by a randomly actuated mixture throttle and upstream by an air throttle controlling the intake air cross section and actuated by the pressure prevailing in the mixing chamber. A bypass air duct discharges into the center of the mixing chamber and receives the fuel supply. A nozzle pin cooperates with the air throttle and controls the cross section of a fuel jet. Downstream of this jet is another fuel jet whose cross section is controllable as a function of engine operating parameters by means of an analog magnet. The fuel jet controlled by the analog magnet may be the fuel outlet in the bypass air duct, and may be controlled by a nozzle pin through a lever via the analog magnet which is a plunger system. The second fuel jet may be located in a bypass air duct and its cross section may also be controlled by an analog magnet as a function of engine operating parameters.
