PURPOSE:To maintain stable fuel supply against fluctuation of engine output or liquid fuel flowing pressure and carry out automatic control of the fuel supply with excellent inclining property by controlling a regulating valve 12 according to the running condition of the engine. CONSTITUTION:When the running of an engine is started to open a throttle valve 24, a throttle valve lever 54 is lifted and a regulating valve 12 also opens a side path 6 to suply proper mixture of air and fuel to the engine. And by setting properly the effective pressure receiving area of a pressure receiving body 5 and the load of a spring 8 is variably controlled an effective flow path gap X correspondingly to fluid pressure change in a flow inlet 1 or flow outlet 2 to maintain approximately constant fluid flow flowing through the gap to the flow outlet 2. Next, when the output of the engine is changed, the regulating valve 12 is inter-locked with the operation of the throttle 24 to determine automatically proper air fuel ratio. |
