Abstract:

PURPOSE: To be adapted to different atmospheric pressure caused by weather irrelative to elevation of the place of use by changing at least one of the air component and fuel component for producing a mixture by means of the open position of a compensation valve in dependence of the ambient air pressure.

CONSTITUTION: A carburetor has a suction duct 1 for producing a mixture of an air component and a fuel component, and a throttle flap valve 3 is arranged downstream of a Venturi portion 2 therein. An idling nozzle 9 communicated with the rotational range of the throttle flap valve 3 and a main nozzle 10 communicated with the Venturi portion 2 upstream of the throttle flap valve 3 are provided. They are communicated with an adjusting chamber 8 via a plurality of throttles 5-7 respectively. Fuel is supplied to the adjusting chamber 8 via a supply valve 11. In such a structure, at least one of the components for producing the mixture can be changed by a compensation valve 20. The open position of the compensation valve 20 can be adjusted by an adjustment device 30 in dependence of the ambient air pressure.
