Abstract

PURPOSE: To prevent discharge delay of fuel during a partial road running by constituting a variable Venturi type carburetor such that a piston returning spring thereof is acted upon by link means which is operated by a throttle valve so as to be compressed during a partial load running.
CONSTITUTION: A piston 4 is disposed perpendicularly to a suction passage 1 which has a throttle valve 2 and a choke valve 3. A negative pressure chamber 10 is defined by a diaphragm 8 connected to the piston 4. Negative pressure is transmitted to the negative pressure chamber 10 by a negative passage 23 formed in the piston 4 to thereby move the piston 4 upwardly and downwardly. A returing spring 14 is disposed in the negative prssure chamber 10 so as to act upon a spacer cylinder 13 fixed to a cam 20 provided on a throttle valve 2 through levers 15, 17, 18. Only during a partial load running of the engine, the cam 20 is contacted with the lever 18 whereby the piston 4 is pressed by the lever 15 through the spacer cylinder 13.
