Abstract

PURPOSE: To obtain a simple-structured fuel feeding device to an engine by detecting differential pressure by an air flow rate differential pressure means and by operating a pressure receiving element which controls fuel by making use of the differential pressure.
CONSTITUTION: Differential pressure in an air passage 11, which is connected to an engine that is not indicated in the figure, is detected by an air flow rate differential pressure detecting means 13 with multiple tongue pieces 14. The differential pressure is transmitted to a pressure receiving element 16 which is constituted to a pressure receiving plate on a wall of the passage 11 to push down said element 16. Also, a fuel flow rate setting mechanism 17 with fuel inlet and outlet 31, 35 and two bellows 28, 29 which form a fuel passage inside is provided at the bottom of the passage. Then, a valve part 38 which divides the bellows and is interlocked with the pressure receiving element 16 is provided in a chamber 18 of the mechanism 17 to open or close a nozzle 34. Fuel is supplied to a combustion chamber through an orifice 33 provided at the valve part 38 corresponding to the operating condition of the nozzle 34.
