  • Control Of The Air-Fuel Ratio Of Carburetors (AREA)

Abstract

PURPOSE: To prevent the ratio of air to fuel from fluctuating due to the production of bubbles and vibration, by horizontally providing an air fuel ratio control needle valve and an orifice and connecting a breathing passage to a chamber in an actuator.
CONSTITUTION: A fuel passage 6 with a main jet 5 is provided under a float chamber 7 to supply fuel from a main nozzle 3. A horizontal passage 8, which communicates with the fuel passage 6, is also provided under the float chamber 7. A horizontal valve rod 12a is provided in the passage 8. The valve rod 12a acts to supply compensatory fuel through the passage 8 depending on intake negative pressure transmitted to a negative pressure chamber 17. A breathing gap 20 defined by a diaphragm 15 and located at the side of the atmosphere is connected to the float chamber 7 so that fuel is introduced into the gap 20. A damper chamber 21 over the gap 20 communicates with the upper space of the float chamber 7 through a breathing passage 16.
